        ## Supported Python Versions
        
        This library supports the following Python versions:
        
        * Python 2.7
        * Python 3.4+
        
        ## Stark Infra API documentation
        
        Feel free to take a look at our [API docs](https://www.starkinfra.com/docs/api).
        
        ## Versioning
        
        This project adheres to the following versioning pattern:
        
        Given a version number MAJOR.MINOR.PATCH, increment:
        
        - MAJOR version when the **API** version is incremented. This may include backwards incompatible changes;
        - MINOR version when **breaking changes** are introduced OR **new functionalities** are added in a backwards compatible manner;
        - PATCH version when backwards compatible bug **fixes** are implemented.
        
        # Setup
        
        ## 1. Install our SDK
        
        1.1 To install the package with pip, run:
        
        ```sh
        pip install starkinfra
        ```
        
        1.2 To install from source, clone the repo and run:
        
        ```sh
        python setup.py install
        ```
        
        ## 2. Create your Private and Public Keys
        
        We use ECDSA. That means you need to generate a secp256k1 private
        key to sign your requests to our API, and register your public key
        with us, so we can validate those requests.
        
        You can use one of the following methods:
        
        2.1. Check out the options in our [tutorial](https://starkbank.com/faq/how-to-create-ecdsa-keys). 
        
        2.2. Use our SDK:
        
        ```python
        import starkinfra
        
        privateKey, publicKey = starkinfra.key.create()
        
        # or, to also save .pem files in a specific path
        privateKey, publicKey = starkinfra.key.create("file/keys/")
        ```
        
        **NOTE**: When you are creating new credentials, it is recommended that you create the
        keys inside the infrastructure that will use it, in order to avoid risky internet
        transmissions of your **private-key**. Then you can export the **public-key** alone to the
        computer where it will be used in the new Project creation.
        
        ## 3. Register your user credentials
        
        You can interact directly with our API using two types of users: Projects and Organizations.
        
        - **Projects** are workspace-specific users, that is, they are bound to the workspaces they are created in.
        One workspace can have multiple Projects.
        - **Organizations** are general users that control your entire organization.
        They can control all your Workspaces and even create new ones. The Organization is bound to your company's tax ID only.
        Since this user is unique in your entire organization, only one credential can be linked to it.
        
        3.1. To create a Project in Sandbox:
        
        3.1.1. Log into [StarkInfra Sandbox](https://web.sandbox.starkinfra.com)
        
        3.1.2. Go to Menu > Integrations
        
        3.1.3. Click on the "New Project" button
        
        3.1.4. Create a Project: Give it a name and upload the public key you created in section 2
        
        3.1.5. After creating the Project, get its Project ID
        
        3.1.6. Use the Project ID and private key to create the object below:
        
        ```python
        import starkinfra
        
        # Get your private key from an environment variable or an encrypted database.
        # This is only an example of a private key content. You should use your own key.
        private_key_content = """
        -----BEGIN EC PARAMETERS-----
        BgUrgQQACg==
        -----END EC PARAMETERS-----
        -----BEGIN EC PRIVATE KEY-----
        MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
        oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
        IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
        -----END EC PRIVATE KEY-----
        """
        
        project = starkinfra.Project(
            environment="sandbox",
            id="5656565656565656",
            private_key=private_key_content
        )
        ```
        
        3.2. To create Organization credentials in Sandbox:
        
        3.2.1. Log into [Starkinfra Sandbox](https://web.sandbox.starkinfra.com)
        
        3.2.2. Go to Menu > Integrations
        
        3.2.3. Click on the "Organization public key" button
        
        3.2.4. Upload the public key you created in section 2 (only a legal representative of the organization can upload the public key)
        
        3.2.5. Click on your profile picture and then on the "Organization" menu to get the Organization ID
        
        3.2.6. Use the Organization ID and private key to create the object below:
        
        ```python
        import starkinfra
        
        # Get your private key from an environment variable or an encrypted database.
        # This is only an example of a private key content. You should use your own key.
        private_key_content = """
        -----BEGIN EC PARAMETERS-----
        BgUrgQQACg==
        -----END EC PARAMETERS-----
        -----BEGIN EC PRIVATE KEY-----
        MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
        oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
        IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
        -----END EC PRIVATE KEY-----
        """
        
        organization = starkinfra.Organization(
            environment="sandbox",
            id="5656565656565656",
            private_key=private_key_content,
            workspace_id=None,  # You only need to set the workspace_id when you are operating a specific workspace_id
        )
        
        ```
        
        NOTE 1: Never hard-code your private key. Get it from an environment variable or an encrypted database.
        
        NOTE 2: We support `'sandbox'` and `'production'` as environments.
        
        NOTE 3: The credentials you registered in `sandbox` do not exist in `production` and vice versa.
        
        
        ## 4. Setting up the user
        
        There are three kinds of users that can access our API: **Organization**, **Project**, and **Member**.
        
        - `Project` and `Organization` are designed for integrations and are the ones meant for our SDKs.
        - `Member` is the one you use when you log into our webpage with your e-mail.
        
        There are two ways to inform the user to the SDK:
        
        4.1 Passing the user as an argument in all functions:
        
        ```python
        import starkinfra
        
        balance = starkinfra.pixbalance.get(user=project)  # or organization
        ```
        
        4.2 Set it as a default user in the SDK:
        
        ```python
        import starkinfra
        
        starkinfra.user = project  # or organization
        
        balance = starkinfra.pixbalance.get()
        ```
        
        Just select the way of passing the user that is more convenient to you.
        On all following examples, we will assume a default user has been set.
        
        ## 5. Setting up the error language
        
        The error language can also be set in the same way as the default user:
        
        ```python
        import starkinfra
        
        starkinfra.language = "en-US"
        ```
        
        Language options are "en-US" for English and "pt-BR" for Brazilian Portuguese. English is the default.
        
        # Resource listing and manual pagination
        
        Almost all SDK resources provide a `query` and a `page` function.
        
        - The `query` function provides a straightforward way to efficiently iterate through all results that match the filters you inform,
        seamlessly retrieving the next batch of elements from the API only when you reach the end of the current batch.
        If you are not worried about data volume or processing time, this is the way to go.
        
        ```python
        import starkinfra
        
        for request in starkinfra.pixrequest.query(limit=200):
            print(request)
        ```
        
        - The `page` function gives you full control over the API pagination. With each function call, you receive up to
        100 results and the cursor to retrieve the next batch of elements. This allows you to stop your queries and
        pick up from where you left off whenever it is convenient. When there are no more elements to be retrieved, the returned cursor will be `None`.
        
        ```python
        import starkinfra
        
        cursor = None
        while True:
            requests, cursor = starkinfra.pixrequest.page(limit=50, cursor=cursor)
            for request in requests:
                print(request)
            if cursor is None:
                break
        ```
        
        To simplify the following SDK examples, we will only use the `query` function, but feel free to use `page` instead.
        
        # Testing in Sandbox
        
        Your initial balance is zero. For many operations in Stark Infra, you'll need funds
        in your account, which can be added to your balance by creating a starkbank.Invoice. 
        
        In the Sandbox environment, most of the created starkbank.Invoices will be automatically paid,
        so there's nothing else you need to do to add funds to your account. Just create
        a few starkbank.Invoice and wait around a bit.
        
        In Production, you (or one of your clients) will need to actually pay this Pix Request
        for the value to be credited to your account.
        
        
        # Usage
        
        Here are a few examples on how to use the SDK. If you have any doubts, use the built-in
        `help()` function to get more info on the desired functionality
        (for example: `help(starkinfra.issuinginvoice.create)`)
        
        ## Issuing
        
        ### Query IssuingProducts
        
        To take a look at the sub-issuer card products available to you, just run the following:
        
        ```python
        import starkinfra
        
        products = starkinfra.issuingproduct.query()
        
        for product in products:
            print(product)
        ```
        
        This will tell which card products and card number prefixes you have at your disposal.
        
        ### Create IssuingHolders
        
        You can create card holders to which your cards will be bound.
        They support spending rules that will apply to all underlying cards.
        
        ```python
        import starkinfra
        
        holders = starkinfra.issuingholder.create([
            starkinfra.IssuingHolder(
                name="Iron Bank S.A.",
                external_id="1234",
                tax_id="012.345.678-90",
                tags=[
                    "Traveler Employee"
                ],
                rules=[
                    {
                        "name": "General USD",
                        "interval": "day",
                        "amount": 100000,
                        "currencyCode": "USD",
                        "categories": [
                            {
                                "type": "services"
                            },
                            {
                                "code": "fastFoodRestaurants"
                            }
                        ],
                        "countries": [
                            {
                                "code": "USA"
                            }
                        ],
                        "methods": [
                            {
                                "code": "token"
                            }
                        ]
                    }
                ]
            )
        ])
        
        for holder in holders:
            print(holder)
        ```
        
        **Note**: Instead of using IssuingHolder objects, you can also pass each element in dictionary format
        
        ### Query IssuingHolders
        
        You can query multiple holders according to filters.
        
        ```python
        import starkinfra
        
        holders = starkinfra.issuingholder.query()
        
        for holder in holders:
            print(holder)
        ```
        
        ### Cancel an IssuingHolder
        
        To cancel a single Issuing Holder by its id, run:
        
        ```python
        import starkinfra
        
        holder = starkinfra.issuingholder.cancel("5155165527080960")
        
        print(holder)
        ```
        
        ### Get an IssuingHolder
        
        To get a single Issuing Holder by its id, run:
        
        ```python
        import starkinfra
        
        holder = starkinfra.issuingholder.get("5155165527080960")
        
        print(holder)
        ```
        
        ### Query IssuingHolder logs
        
        You can query holder logs to better understand holder life cycles.
        
        ```python
        import starkinfra
        
        logs = starkinfra.issuingholder.log.query(limit=50)
        
        for log in logs:
            print(log.id)
        ```
        
        ### Get an IssuingHolder log
        
        You can also get a specific log by its id.
        
        ```python
        import starkinfra
        
        log = starkinfra.issuingholder.log.get("5155165527080960")
        
        print(log)
        ```
        
        ### Create IssuingCards
        
        You can issue cards with specific spending rules.
        
        ```python
        import starkinfra
        
        cards = starkinfra.issuingcard.create([
            starkinfra.IssuingCard(
                holder_name="Developers",
                holder_tax_id="012.345.678-90",
                holder_external_id="1234",
                rules=[starkinfra.IssuingRule(
                    name="general",
                    interval="week",
                    amount=50000,
                    currency_code="USD",
                    categories=[
                        starkinfra.MerchantCategory(type="services"),  # Covers all service-related MCCs
                        starkinfra.MerchantCategory(code="fastFoodRestaurants")  # Covers a specific MCC
                    ],
                    countries=[
                        starkinfra.MerchantCountry(code="BRA")
                    ],
                    methods=[
                        starkinfra.CardMethod(code="token")
                    ]
                )]
            )
        ])
        
        for card in cards:
            print(card)
        ```
        
        ### Query IssuingCards
        
        You can get a list of created cards given some filters.
        
        ```python
        import starkinfra
        from datetime import datetime
        
        cards = starkinfra.issuingcard.query(
            after=datetime(2020, 1, 1),
            before=datetime(2020, 3, 1)
        )
        
        for card in cards:
            print(card)
        ```
        
        ### Get an IssuingCard
        
        After its creation, information on a card may be retrieved by its id.
        
        ```python
        import starkinfra
        
        card = starkinfra.issuingcard.get("5155165527080960")
        
        print(card)
        ```
        
        ### Update an IssuingCard
        
        You can update a specific card by its id.
        
        ```python
        import starkinfra
        
        card = starkinfra.issuingcard.update("5155165527080960", status="blocked")
        
        print(card)
        ```
        
        ### Cancel an IssuingCard
        
        You can also cancel a card by its id.
        
        ```python
        import starkinfra
        
        card = starkinfra.issuingcard.cancel("5155165527080960")
        
        print(card)
        ```
        
        ### Query IssuingCard logs
        
        Logs are pretty important to understand the life cycle of a card.
        
        ```python
        import starkinfra
        
        logs = starkinfra.issuingcard.log.query(limit=150)
        
        for log in logs:
            print(log)
        ```
        
        ### Get an IssuingCard log
        
        You can get a single log by its id.
        
        ```python
        import starkinfra
        
        log = starkinfra.issuingcard.log.get("5155165527080960")
        
        print(log)
        ```
        
        ### Process Purchase authorizations
        
        It's easy to process purchase authorizations delivered to your endpoint.
        Remember to pass the signature header so the SDK can make sure it's StarkInfra that sent you the event.
        If you do not approve or decline the authorization within 2 seconds, the authorization will be denied.
        
        ```python
        import starkinfra
        
        request = listen()  # this is the method you made to get the events posted to your webhook endpoint
        
        authorization = starkinfra.issuingpurchase.parse(
            content=request.data.decode("utf-8"),
            signature=request.headers["Digital-Signature"],
        )
        
        sendResponse(  # you should also implement this method
            starkinfra.issuingpurchase.response(  # this optional method just helps you build the response JSON
                status="approved",
                amount=authorization.amount,
                tags=["my-purchase-id/123"],
            )
        )
        
        # or 
        
        sendResponse(
            starkinfra.issuingpurchase.response(
                status="denied",
                reason="other",
                tags=["other-id/456"],
            )
        )
        ```
        
        ### Query IssuingPurchases
        
        You can get a list of created purchases given some filters.
        
        ```python
        import starkinfra
        from datetime import datetime
        
        purchases = starkinfra.issuingpurchase.query(
            after=datetime(2020, 1, 1),
            before=datetime(2020, 3, 1)
        )
        
        for purchase in purchases:
            print(purchase)
        ```
        
        ### Get an IssuingPurchase
        
        After its creation, information on a purchase may be retrieved by its id. 
        
        ```python
        import starkinfra
        
        purchase = starkinfra.issuingpurchase.get("5155165527080960")
        
        print(purchase)
        ```
        
        ### Query IssuingPurchase logs
        
        Logs are pretty important to understand the life cycle of a purchase.
        
        ```python
        import starkinfra
        
        logs = starkinfra.issuingpurchase.log.query(limit=150)
        
        for log in logs:
            print(log)
        ```
        
        ### Get an IssuingPurchase log
        
        You can get a single log by its id.
        
        ```python
        import starkinfra
        
        log = starkinfra.issuingpurchase.log.get("5155165527080960")
        
        print(log)
        ```
        
        ### Create IssuingInvoices
        
        You can create Pix invoices to transfer money from accounts you have in any bank to your Issuing balance,
        allowing you to run your issuing operation.
        
        ```python
        import starkinfra
        
        invoice = starkinfra.issuinginvoice.create(
            invoice=starkinfra.IssuingInvoice(
                amount=1000
            )
        )
        
        print(invoice)
        ```
        
        **Note**: Instead of using IssuingInvoice objects, you can also pass each element in dictionary format
        
        ### Get an IssuingInvoice
        
        After its creation, information on an invoice may be retrieved by its id. 
        Its status indicates whether it's been paid.
        
        ```python
        import starkinfra
        
        invoice = starkinfra.issuinginvoice.get("5155165527080960")
        
        print(invoice)
        ```
        
        ### Query IssuingInvoices
        
        You can get a list of created invoices given some filters.
        
        ```python
        import starkinfra
        from datetime import datetime
        
        invoices = starkinfra.issuinginvoice.query(
            after=datetime(2020, 1, 1),
            before=datetime(2020, 3, 1)
        )
        
        for invoice in invoices:
            print(invoice)
        ```
        
        ### Query IssuingInvoice logs
        
        Logs are pretty important to understand the life cycle of an invoice.
        
        ```python
        import starkinfra
        
        logs = starkinfra.issuinginvoice.log.query(limit=150)
        
        for log in logs:
            print(log)
        ```
        
        ### Get an IssuingInvoice log
        
        You can also get a specific log by its id.
        
        ```python

        log = starkinfra.issuinginvoice.log.get("5155165527080960")
        
        print(log)
        ```
        
        ### Create IssuingWithdrawals
        
        You can create withdrawals to send cash back from your Issuing balance to your Banking balance
        by using the Withdrawal resource.
        
        ```python
        import starkinfra
        
        withdrawal = starkinfra.issuingwithdrawal.create(
            withdrawal=starkinfra.IssuingWithdrawal(
                amount=10000,
                external_id="123",
                description="Sending back"
            )
        )
        
        print(withdrawal)
        ```
        
        **Note**: Instead of using IssuingWithdrawal objects, you can also pass each element in dictionary format
        
        ### Get an IssuingWithdrawal
        
        After its creation, information on a withdrawal may be retrieved by its id.
        
        ```python
        import starkinfra
        
        invoice = starkinfra.issuingwithdrawal.get("5155165527080960")
        
        print(invoice)
        ```
        
        ### Query IssuingWithdrawals
        
        You can get a list of created withdrawals given some filters.
        
        ```python
        import starkinfra
        from datetime import datetime
        
        withdrawals = starkinfra.issuingwithdrawal.query(
            after=datetime(2020, 1, 1),
            before=datetime(2020, 3, 1)
        )
        
        for withdrawal in withdrawals:
            print(withdrawal)
        ```
        
        ### Get your IssuingBalance
        
        To know how much money you have available to run authorizations, run:
        
        ```python
        import starkinfra
        
        balance = starkinfra.issuingbalance.get()
        
        print(balance)
        ```
        
        ### Query IssuingTransactions
        
        To understand your balance changes (issuing statement), you can query
        transactions. Note that our system creates transactions for you when
        you make purchases, withdrawals, receive issuing invoice payments, for example.
        
        ```python
        import starkinfra
        
        transactions = starkinfra.issuingtransaction.query(
            after="2020-01-01",
            before="2020-03-01"
        )
        for transaction in transactions:
            print(transaction)
        ```
        
        ### Get an IssuingTransaction
        
        You can get a specific transaction by its id:
        
        ```python
        import starkinfra
        
        transaction = starkinfra.issuingtransaction.get("5155165527080960")
        
        print(transaction)
        ```
        
        ### Issuing Enums
        
        #### Query MerchantCategories
        
        You can query any merchant categories using this resource.
        You may also use MerchantCategories to define specific category filters in IssuingRules.
        Either codes (which represents specific MCCs) or types (code groups) will be accepted as filters.
        
        ```python
        import starkinfra
        
        categories = starkinfra.merchantcategory.query(
            search="food",
        )
        
        for category in categories:
            print(category)
        ```
        
        #### Query MerchantCountries
        
        You can query any merchant countries using this resource.
        You may also use MerchantCountries to define specific country filters in IssuingRules.
        
        ```python
        import starkinfra
        
        countries = starkinfra.merchantcountry.query(
            search="brazil",
        )
        
        for country in countries:
            print(country)
        ```
        
        #### Query CardMethods
        
        You can query available card methods using this resource.
        You may also use CardMethods to define specific purchase method filters in IssuingRules.
        
        ```python
        import starkinfra
        
        methods = starkinfra.cardmethod.query(
            search="token",
        )
        
        for method in methods:
            print(method)
        ```
        
        ## Pix
        
        ### Create PixRequests
        
        You can create a Pix request to transfer money from one of your users to anyone else:
        
        ```python
        import starkinfra
        
        requests = starkinfra.pixrequest.create([
            starkinfra.PixRequest(
                amount=100,  # (R$ 1.00)
                external_id="141234121",  # so we can block anything you send twice by mistake
                sender_branch_code="0000",
                sender_account_number="00000-0",
                sender_account_type="checking",
                sender_name="Tyrion Lannister",
                sender_tax_id="012.345.678-90",
                receiver_bank_code="00000001",
                receiver_branch_code="0001",
                receiver_account_number="00000-1",
                receiver_account_type="checking",
                receiver_name="Jamie Lannister",
                receiver_tax_id="45.987.245/0001-92",
                end_to_end_id=starkinfra.endtoendid.create("20018183"),  # Pass your bank code to create an end to end ID
                description="For saving my life",
            ),
            starkinfra.PixRequest(
                amount=200,  # (R$ 2.00)
                external_id="2135613462",  # so we can block anything you send twice by mistake
                sender_account_number="00000-0",
                sender_branch_code="0000",
                sender_account_type="checking",
                sender_name="Arya Stark",
                sender_tax_id="012.345.678-90",
                receiver_bank_code="00000001",
                receiver_account_number="00000-1",
                receiver_branch_code="0001",
                receiver_account_type="checking",
                receiver_name="John Snow",
                receiver_tax_id="012.345.678-90",
                end_to_end_id=starkinfra.endtoendid.create("20018183"),  # Pass your bank code to create an end to end ID
                tags=["Needle", "sword"],
            )
        ])
        
        for request in requests:
            print(request)
        ```
        
        **Note**: Instead of using PixRequest objects, you can also pass each element in dictionary format
        
        ### Query PixRequests
        
        You can query multiple Pix requests according to filters.
        
        ```python
        import starkinfra
        from datetime import datetime
        
        requests = starkinfra.pixrequest.query(
            limit=10,
            after=datetime(2020, 1, 1),
            before=datetime(2020, 4, 1),
            status="success",
            tags=["iron", "suit"],
            end_to_end_ids=["E79457883202101262140HHX553UPqeq"],
        )
        
        for request in requests:
            print(request)
        ```
        
        ### Get a PixRequest
        
        After its creation, information on a Pix request may be retrieved by its id. Its status indicates whether it has been paid.
        
        ```python
        import starkinfra
        
        request = starkinfra.pixrequest.get("5155165527080960")
        
        print(request)
        ```
        
        ### Process inbound PixRequest authorizations
        
        It's easy to process authorization requests that arrived at your endpoint.
        Remember to pass the signature header so the SDK can make sure it's StarkInfra that sent you the event.
        If you do not approve or decline the authorization within 1 second, the authorization will be denied.
        
        ```python
        import starkinfra
        
        request = listen()  # this is your handler to listen for authorization requests
        
        pix_request = starkinfra.pixrequest.parse(
            content=request.data.decode("utf-8"),
            signature=request.headers["Digital-Signature"],
        )
        
        print(pix_request)
        
        sendResponse(  # you should also implement this method
            starkinfra.pixrequest.response(  # this optional method just helps you build the response JSON
                status="approved",
            )
        )
        
        # or 
        
        sendResponse(
            starkinfra.pixrequest.response(
                status="denied",
                reason="orderRejected",
            )
        )
        ```
          
        ### Query PixRequest logs
        
        You can query Pix request logs to better understand Pix request life cycles. 
        
        ```python
        import starkinfra
        
        logs = starkinfra.pixrequest.log.query(
            limit=50, 
            after="2022-01-01",
            before="2022-01-20",
        )
        
        for log in logs:
            print(log)
        ```
        
        ### Get a PixRequest log
        
        You can also get a specific log by its id.
        
        ```python
        import starkinfra
        
        log = starkinfra.pixrequest.log.get("5155165527080960")
        
        print(log)
        ```
        
        ### Create PixReversals
        
        You can reverse a PixRequest either partially or totally using a PixReversal.
        
        ```python
        import starkinfra
        
        reversal = starkinfra.pixreversal.create([
            starkinfra.PixReversal(
                amount=100,
                end_to_end_id="E00000000202201060100rzsJzG9PzMg",
                external_id="17238435823958934",
                reason="bankError",
            )
        ])
        
        print(reversal)
        ```
        
        ### Query PixReversals 
        
        You can query multiple Pix reversals according to filters. 
        
        ```python
        import starkinfra
        from datetime import datetime
        
        reversals = starkinfra.pixreversal.query(
            limit=10,
            after=datetime(2020, 1, 1),
            before=datetime(2020, 4, 1),
            status="success",
            tags=["iron", "suit"],
            return_ids=["D20018183202202030109X3OoBHG74wo"],
        )
        
        for reversal in reversals:
            print(reversal)
        ```
        
        ### Get a PixReversal
        
        After its creation, information on a Pix reversal may be retrieved by its id.
        Its status indicates whether it has been successfully processed.
        
        ```python
        import starkinfra
        
        reversal = starkinfra.pixreversal.get("5155165527080960")
        
        print(reversal)
        ```
        
        ### Process inbound PixReversal authorizations
        
        It's easy to process authorization requests that arrived at your endpoint.
        Remember to pass the signature header so the SDK can make sure it's StarkInfra that sent you the event.
        If you do not approve or decline the authorization within 1 second, the authorization will be denied.
        
        ```python
        import starkinfra
        
        request = listen()  # this is your handler to listen for authorization requests
        
        reversal = starkinfra.pixreversal.parse(
            content=request.data.decode("utf-8"),
            signature=request.headers["Digital-Signature"],
        )
        
        print(reversal)
        
        sendResponse(  # you should also implement this method
            starkinfra.pixreversal.response(  # this optional method just helps you build the response JSON
                status="approved",
            )
        )
        
        # or 
        
        sendResponse(
            starkinfra.pixreversal.response(
                status="denied",
                reason="orderRejected",
            )
        )
        ```
        
        ### Query PixReversal logs

        statement = starkinfra.pixstatement.get("5155165527080960")
        
        print(statement)
        ```
        
        ### Get a PixStatement .csv file
        
        To get the .csv file corresponding to a Pix statement using its id, run:
        
        ```python
        import starkinfra
        
        csv = starkinfra.pixstatement.csv("5155165527080960")
        
        with open("test.zip", "wb") as file:
            file.write(csv)
        ```
        
        ### Create a PixKey

        ```python
        import starkinfra
        
        key = starkinfra.pixkey.create(
            starkinfra.PixKey(
                account_created="2022-02-01T00:00:00.00",
                account_number="00000",
                account_type="savings",
                branch_code="0000",
                name="Jamie Lannister",
                tax_id="012.345.678-90",
                id="+5511989898989",
            )
        )
        
        print(key)
        ```
        
        ### Query PixKeys

        ```
        
        ### Get a PixKey
        
        Information on a Pix key may be retrieved by its id and the tax ID of the consulting agent.
        An endToEndId must be informed so you can link any resulting purchases to this query,
        avoiding sweep blocks by the Central Bank.
        
        ```python
        import starkinfra
        
        key = starkinfra.pixkey.get(
            "5155165527080960",
            payer_id="012.345.678-90",
            end_to_end_id=starkinfra.endtoendid.create("20018183"),
        )
        
        print(key)
        ```
        
        ### Update a PixKey
        
        Update the account information linked to a Pix Key.

        ```
        
        ### Create a PixClaim
        
        You can create a Pix claim to request the transfer of a Pix key from another bank to one of your accounts:
        
        ```python
        import starkinfra
        
        claim = starkinfra.pixclaim.create(
            starkinfra.PixClaim(
                account_created="2022-02-01T00:00:00.00",
                account_number="5692908409716736",
                account_type="checking",
                branch_code="0000",
                name="testKey",
                tax_id="012.345.678-90",
                key_id="+5511989898989"
            )
        )
        
        print(claim)
        ```
        
        ### Query PixClaims
        
        You can query multiple Pix claims according to filters.
        
        ```python
        import starkinfra
        
        claims = starkinfra.pixclaim.query(
            limit=1,
            after="2022-01-01",
            before="2022-01-12",
            status="registered",
            ids=["5729405850615808"],
            type="ownership",
            flow="out",
            key_type="phone",
            key_id="+5511989898989"
        )
        
        for claim in claims:
            print(claim)
        ```
        
        ### Get a PixClaim
        
        After its creation, information on a Pix claim may be retrieved by its id.
        
        ```python
        import starkinfra
        
        claim = starkinfra.pixclaim.get("5155165527080960")
        
        print(claim)
        ```
        
        ### Update a PixClaim
        
        A Pix Claim can be confirmed or canceled by patching its status.
        A received Pix Claim must be confirmed by the donor to be completed.
        Ownership Pix Claims can only be canceled by the donor if the reason is "fraud".
        A sent Pix Claim can also be canceled.
        
        ```python
        import starkinfra
        
        claim = starkinfra.pixclaim.update(
            id="5155165527080960",
            status="confirmed"
        )

        logs = starkinfra.pixclaim.log.query(
            limit=50, 
            ids=["5729405850615808"],
            after="2022-01-01",
            before="2022-01-20",
            types=["registered"],
            claim_ids=["5719405850615809"]
        )
        
        for log in logs:
            print(log)
        ```
        
        ### Get a PixClaim log
        
        You can also get a specific log by its id.

        )
        
        print(director)
        ```
        
        ### Create PixInfractions
        
        Pix Infraction reports are used to report transactions that raise fraud suspicion, to request a refund or to 
        reverse a refund. Infraction reports can be created by either participant of a transaction.
        
        ```python
        import starkinfra
        
        infractions = starkinfra.pixinfraction.create(
            infractions=[
                starkinfra.PixInfraction(
                    reference_id="E20018183202201201450u34sDGd19lz",
                    type="fraud",
                )

        name and the QR Code domain certificates of registered Pix participants able to issue dynamic QR Codes.
        
        ```python
        import starkinfra
        
        domains = starkinfra.pixdomain.query()
        for domain in domains:
            print(domain)
        ```
        
        ### Create StaticBrcodes
        
        StaticBrcodes store account information via a BR code or an image (QR code)
        that represents a PixKey and a few extra fixed parameters, such as an amount 
        and a reconciliation ID. They can easily be used to receive Pix transactions.
        
        ```python
        import starkinfra
        
        brcodes = starkinfra.staticbrcode.create([
            starkinfra.StaticBrcode(
                name="Jamie Lannister",
                key_id="+5511988887777",
                amount=100,
                reconciliation_id="123",
                city="Rio de Janeiro"
            )
        ])
        
        for brcode in brcodes:
            print(brcode)
        ```
        
        ### Query StaticBrcodes
        
        You can query multiple StaticBrcodes according to filters.
        
        ```python
        import starkinfra
        
        brcodes = starkinfra.staticbrcode.query(
            limit=1,
            after="2022-06-01",
            before="2022-06-30",
            uuids=["5ddde28043a245c2848b08cf315effa2"]
        )
        
        for brcode in brcodes:
            print(brcode)
        ```
        
        ### Get a StaticBrcodes
        
        After its creation, information on a StaticBrcode may be retrieved by its UUID.
        
        ```python
        import starkinfra
        
        brcode = starkinfra.staticbrcode.get("5ddde28043a245c2848b08cf315effa2")
        
        print(brcode)
        ```
        
        ### Create DynamicBrcodes
        
        BR codes store information represented by Pix QR Codes, which are used to send 
        or receive Pix transactions in a convenient way.
        DynamicBrcodes represent charges with information that can change at any time,
        since all data needed for the payment is requested dynamically to an URL stored
        in the BR Code. Stark Infra will receive the GET request and forward it to your
        registered endpoint with a GET request containing the UUID of the BR code for
        identification.
        
        ```python
        import starkinfra
        
        brcodes = starkinfra.dynamicbrcode.create([
            starkinfra.DynamicBrcode(
                name="Jamie Lannister",
                city="Rio de Janeiro",
                external_id="my_unique_id_01",
                type="instant"
            )
        ])
        
        for brcode in brcodes:
            print(brcode)
        ```
        
        ### Query DynamicBrcodes
        
        You can query multiple DynamicBrcodes according to filters.
        
        ```python
        import starkinfra
        
        brcodes = starkinfra.dynamicbrcode.query(
            limit=1,
            after="2022-06-01",
            before="2022-06-30",
            uuids=["ac7caa14e601461dbd6b12bf7e4cc48e"]
        )
        
        for brcode in brcodes:
            print(brcode)
        ```
        
        ### Get a DynamicBrcode
        
        After its creation, information on a DynamicBrcode may be retrieved by its UUID.
        
        ```python
        import starkinfra
        
        brcode = starkinfra.dynamicbrcode.get("ac7caa14e601461dbd6b12bf7e4cc48e")
        
        print(brcode)
        ```
        
        ### Verify a DynamicBrcode read
        
        When a DynamicBrcode is read by your user, a GET request will be made to the your regitered URL to 
        retrieve additional information needed to complete the transaction.
        Use this method to verify the authenticity of a GET request received at your registered endpoint.
        If the provided digital signature does not check out with the StarkInfra public key, a stark.exception.InvalidSignatureException will be raised.
        
        ```python
        import starkinfra
        
        request = listen()  # this is the method you made to get the read requests posted to your registered endpoint
        
        uuid = starkinfra.dynamicbrcode.verify(
            uuid=request.url.get_parameter("uuid"),
            signature=request.headers["Digital-Signature"],
        )
        ```
        
        ### Answer to a Due DynamicBrcode read
        
        When a Due DynamicBrcode is read by your user, a GET request containing 
        the BR code UUID will be made to your registered URL to retrieve additional 
        information needed to complete the transaction.
        
        The GET request must be answered in the following format within 5 seconds 
        and with an HTTP status code 200.
        
        ```python
        import starkinfra
        
        request = listen()  # this is the method you made to get the read requests posted to your registered endpoint
        
        uuid = starkinfra.dynamicbrcode.verify(
            uuid=request.url.get_parameter("uuid"),
            signature=request.headers["Digital-Signature"],
        )
        
        invoice = get_my_invoice(uuid) # you should implement this method to get the information of the BR code from its uuid
        
        send_response(  # you should also implement this method to respond the read request
            starkinfra.dynamicbrcode.response_due(
                version=invoice.version,
                created=invoice.created,
                due=invoice.due,

                receiver_city=invoice.receiver_city,
                receiver_state_code=invoice.receiver_state_code,
                receiver_zip_code=invoice.receiver_zip_code
            )
        )
        ```
        
        ### Answer to an Instant DynamicBrcode read
        
        When an Instant DynamicBrcode is read by your user, a GET request 
        containing the BR code UUID will be made to your registered URL to retrieve 
        additional information needed to complete the transaction.
        
        The get request must be answered in the following format 
        within 5 seconds and with an HTTP status code 200.
        
        ```python
        import starkinfra

            signature=request.headers["Digital-Signature"],
        )
        
        invoice = get_my_invoice(uuid) # you should implement this method to get the information of the BR code from its uuid
        
        send_response(  # you should also implement this method to respond the read request
            starkinfra.issuingpurchase.response_instant(
                version=invoice.version,
                created=invoice.created,
                key_id=invoice.key_id,
                status=invoice.status,

            print(note)
        ```
        
        **Note**: Instead of using CreditNote objects, you can also pass each element in dictionary format
        
        ### Query CreditNotes
        
        You can query multiple credit notes according to filters.
        
        ```python
        import starkinfra
        from datetime import datetime
        
        notes = starkinfra.creditnote.query(
            limit=10,
            after=datetime(2020, 1, 1),
            before=datetime(2020, 4, 1),
            status="success",
            tags=["iron", "suit"],
        )
        
        for note in notes:
            print(note)
        ```
        
        ### Get a CreditNote
        
        After its creation, information on a credit note may be retrieved by its id.
        
        ```python
        import starkinfra
        
        note = starkinfra.creditnote.get("5155165527080960")
        
        print(note)
        ```
        
        ### Cancel a CreditNote
        
        You can cancel a credit note if it has not been signed yet.
        
        ```python
        import starkinfra
        
        note = starkinfra.creditnote.cancel("5155165527080960")
        
        print(note)
        ```
          
        ### Query CreditNote logs
        
        You can query credit note logs to better understand credit note life cycles. 
        
        ```python
        import starkinfra
        
        logs = starkinfra.creditnote.log.query(
            limit=50, 
            after="2022-01-01",
            before="2022-01-20",
        )
        
        for log in logs:
            print(log)
        ```
        
        ### Get a CreditNote log
        
        You can also get a specific log by its id.
        
        ```python
        import starkinfra
        
        log = starkinfra.creditnote.log.get("5155165527080960")
        
        print(log)
        ```
        
        ## Credit Preview
        You can preview different types of credits before creating them (Currently we only have CreditNote previews):
        
        ### Create a CreditNotePreview
        You can preview a Credit Note before the creation of the CCB contract:
        
        ```python
        import starkinfra
        
        previews = starkinfra.creditpreview.create([
            starkinfra.CreditPreview(
                type="credit-note"
                credit=starkinfra.creditpreview.CreditNotePreview(

                            due="2022-08-19"
                        ),
                        starkinfra.creditnote.Invoice(
                            amount=14500,
                            due="2022-09-25"

        ])
        
        for preview in previews:
            print(preview)
        ```
        
        **Note**: Instead of using CreditPreview objects, you can also pass each element in dictionary format
        
        ## Webhook
        
        ### Create a webhook subscription
        
        To create a webhook subscription and be notified whenever an event occurs, run:
        
        ```python
        import starkinfra
        
        webhook = starkinfra.webhook.create(
            url="https://webhook.site/dd784f26-1d6a-4ca6-81cb-fda0267761ec",
            subscriptions=[
                "credit-note",
                "issuing-card", "issuing-invoice", "issuing-purchase",
                "pix-request.in", "pix-request.out", "pix-reversal.in", "pix-reversal.out", "pix-claim", "pix-key", "pix-chargeback", "pix-infraction",
            ],
        )
        
        print(webhook)
        ```
        
        ### Query webhooks
        
        To search for registered webhooks, run:
        
        ```python
        import starkinfra
        
        webhooks = starkinfra.webhook.query()
        
        for webhook in webhooks:
            print(webhook)
        ```
        
        ### Get a webhook
        
        You can get a specific webhook by its id.
        
        ```python
        import starkinfra
        
        webhook = starkinfra.webhook.get("1082736198236817")
        
        print(webhook)
        ```
        
        ### Delete a webhook
        
        You can also delete a specific webhook by its id.
        
        ```python
        import starkinfra
        
        webhook = starkinfra.webhook.delete("1082736198236817")
        
        print(webhook)
        ```
        
        ### Process webhook events
        
        It's easy to process events delivered to your Webhook endpoint.
        Remember to pass the signature header so the SDK can make sure it was StarkInfra that sent you the event.
        
        ```python
        import starkinfra
        
        request = listen()  # this is the method you made to get the events posted to your webhook endpoint
        
        event = starkinfra.event.parse(
            content=request.data.decode("utf-8"),
            signature=request.headers["Digital-Signature"],
        )
        
        if "pix-request" in event.subscription:
            print(event.log.request)
        
        elif "pix-reversal" in event.subscription:
            print(event.log.reversal)
        
        elif "issuing-card" in event.subscription:
            print(event.log.card)
        
        elif "issuing-invoice" in event.subscription:
            print(event.log.invoice)
        
        elif "issuing-purchase" in event.subscription:
            print(event.log.purchase)
        
        elif "credit-note" in event.subscription:
            print(event.log.note)
        ```
        
        ### Query webhook events
        
        To search for webhooks events, run:
        
        ```python
        import starkinfra
        
        events = starkinfra.event.query(after="2020-03-20", is_delivered=False)
        
        for event in events:
            print(event)
        ```
        
        ### Get a webhook event
        
        You can get a specific webhook event by its id.
        
        ```python
        import starkinfra
        
        event = starkinfra.event.get("1082736198236817")
        
        print(event)
        ```
        
        ### Delete a webhook event
        
        You can also delete a specific webhook event by its id.
        
        ```python
        import starkinfra
        
        event = starkinfra.event.delete("10827361982368179")
        
        print(event)
        ```
        
        ### Set webhook events as delivered
        
        This can be used in case you've lost events.
        With this function, you can manually set events retrieved from the API as
        "delivered" to help future event queries with `is_delivered=False`.
        
        ```python
        import starkinfra
        
        event = starkinfra.event.update(id="1298371982371921", is_delivered=True)
        
        print(event)
        ```
        
        ### Query failed webhook event delivery attempts information
        
        You can also get information on failed webhook event delivery attempts.
        
        ```python
        import starkinfra
        
        attempts = starkinfra.event.attempt.query(after="2020-03-20")
        
        for attempt in attempts:
            print(attempt.code)
            print(attempt.message)
        ```
        
        ### Get a failed webhook event delivery attempt information
        
        To retrieve information on a single attempt, use the following function:
        
        ```python
        import starkinfra
        
        attempt = starkinfra.event.attempt.get("1616161616161616")
        
        print(attempt)
        ```
        
        # Handling errors
        
        The SDK may raise one of four types of errors: __InputErrors__, __InternalServerError__, __UnknownError__, __InvalidSignatureError__
        
        __InputErrors__ will be raised whenever the API detects an error in your request (status code 400).
        If you catch such an error, you can get its elements to verify each of the
        individual errors that were detected in your request by the API.
        For example:
        
        ```python
        import starkinfra
        
        try:
            reversal = starkinfra.pixreversal.create([
                starkinfra.PixReversal(
                    amount=100,
                    end_to_end_id="E00000000202201060100rzsJzG9PzMg",
                    external_id="1723843582395893",
                    reason="bankError",
                )
            ])
        except starkinfra.error.InputErrors as exception:
            for error in exception.errors:
                print(error.code)
                print(error.message)
        ```
        
        __InternalServerError__ will be raised if the API runs into an internal error.
        If you ever stumble upon this one, rest assured that the development team
        is already rushing in to fix the mistake and get you back up to speed.
        
        __UnknownError__ will be raised if a request encounters an error that is
        neither __InputErrors__ nor an __InternalServerError__, such as connectivity problems.
        
        __InvalidSignatureError__ will be raised specifically by starkinfra.event.parse()
        when the provided content and signature do not check out with the Stark Infra public
        key.
