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.

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:

pip install starkinfra

1.2 To install from source, clone the repo and run:

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.

2.2. Use our SDK:

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

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:

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

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

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:

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:

import starkinfra

balance = starkinfra.pixbalance.get(user=project)  # or organization

4.2 Set it as a default user in the SDK:

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:

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.

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.

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:

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.

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"
                    }
                ]
            }
        ]
    )
])

            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=[

        method_code="app"
    )
)

print(request)

Process Token authorizations

It's easy to process token 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.

import starkinfra

request = listen()  # this is the method you made to get the events posted to your tokenAuthorizationUrl endpoint

authorization = starkinfra.issuingtoken.parse(
    content=request.data.decode("utf-8"),
    signature=request.headers["Digital-Signature"],
)

sendResponse(
    starkinfra.issuingtoken.response_authorization( # this optional method just helps you build the response JSON
        status="approved",
        activation_methods=[
            {
                "type": "app",
                "value": "com.subissuer.android"
            },
            {
                "type": "text",
                "value": "** *****-5678"
            }
        ],
        design_id="4584031664472031",
        tags=["token", "user/1234"],
    )
)

# or

sendResponse(
    starkinfra.issuingtoken.response_authorization( # this optional method just helps you build the response JSON
        status="denied",
        reason="other",
    )
)

Process Token activations

It's easy to process token activation notifications delivered to your endpoint. Remember to pass the signature header so the SDK can make sure it's Stark Infra that sent you the event.

import starkinfra

request = listen()  # this is the method you made to get the events posted to your tokenActivationUrl endpoint

authorization = starkinfra.issuingtokenactivation.parse(
    content=request.data.decode("utf-8"),
    signature=request.headers["Digital-Signature"],
)

After that, you may generate the activation code and send it to the cardholder. The cardholder enters the received code in the wallet app. We'll receive and send it to tokenAuthorizationUrl for your validation. Completing the provisioning process.

import starkinfra

request = listen()  # this is the method you made to get the events posted to your tokenAuthorizationUrl endpoint

activation = starkinfra.issuingtoken.parse(
    content=request.data.decode("utf-8"),
    signature=request.headers["Digital-Signature"],
)

sendResponse(
    starkinfra.issuingtoken.response_activation( # this optional method just helps you build the response JSON
        status="approved",
        tags=["token", "user/1234"]
    )
)

# or

sendResponse(
    starkinfra.issuingtoken.response_activation( # this optional method just helps you build the response JSON
        status="denied",
        reason="other",
        tags=["token", "user/1234"]
    )
)

Get an IssuingToken

You can get a single token by its id.

import starkinfra

token = starkinfra.issuingtoken.get(id="5749080709922816")

print(token)

Query IssuingTokens

You can get a list of created tokens given some filters.

import starkinfra

tokens = starkinfra.issuingtoken.query(
    limit=5,
    after=date.today() - timedelta(days=100),
    before=date.today(),
    status="active",
    card_ids=["5656565656565656", "4545454545454545"],
    external_ids=["DSHRMC00002626944b0e3b539d4d459281bdba90c2588791", "DSHRMC00002626941c531164a0b14c66ad9602ee716f1e85"]
)

for token in tokens:
    print(token)

Update an IssuingToken

You can update a specific token by its id.

import starkinfra

token = starkinfra.issuingtoken.update(id="5155165527080960", status="blocked")

print(token)

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.

import starkinfra

brcodes = starkinfra.staticbrcode.create([
    starkinfra.StaticBrcode(
        name="Jamie Lannister",
        key_id="+5511988887777",

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.

import starkinfra

brcodes = starkinfra.dynamicbrcode.create([
    starkinfra.DynamicBrcode(
        name="Jamie Lannister",
        city="Rio de Janeiro",
        external_id="my_unique_id_01",

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 your registered 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.

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.

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,
        key_id=invoice.key_id,
        status=invoice.status,
        reconciliation_id=invoice.reconciliation_id,
        amount=invoice.amount,
        sender_name=invoice.sender_name,
        sender_tax_id=invoice.sender_tax_id,
        receiver_name=invoice.receiver_name,
        receiver_tax_id=invoice.receiver_tax_id,
        receiver_street_line=invoice.receiver_street_line,
        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.

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.issuingpurchase.response_instant(

    ),
])

for preview in previews:
    print(preview)

Lending

If you want to establish a lending operation, you can use Stark Infra to create a CCB contract. This will enable your business to lend money without requiring a banking license, as long as you use a Credit Fund or Securitization company.

The required steps to initiate the operation are:

Have funds in your Credit Fund or Securitization account
Request the creation of an Identity Check for the credit receiver (make sure you have their documents and express authorization)
(Optional) Create a Credit Simulation with the desired installment plan to display information for the credit receiver
Create a Credit Note with the desired installment plan

Create CreditNotes

For lending operations, you can create a CreditNote to generate a CCB contract.

Note that you must have recently created an identity check for that same Tax ID before being able to create a credit operation for them.

import starkinfra

Identity

Several operations, especially credit ones, require that the identity of a person or business is validated beforehand.

Identities are validated according to the following sequence:

The Identity resource is created for a specific Tax ID
Documents are attached to the Identity resource
The Identity resource is updated to indicate that all documents have been attached
The Identity is sent for validation and returns a webhook notification to reflect the success or failure of the operation

Create IndividualIdentities

You can create an IndividualIdentity to validate a document of a natural person

    starkinfra.IndividualDocument(
        type="identity-front",
        content="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIAAD...",
        identity_id='5155165527080960',
        tags=["breaking", "bad"]
    ),
    starkinfra.IndividualDocument(
        type="identity-back",
        content="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIAAD...",
        identity_id='5155165527080960',
        tags=["breaking", "bad"]
    ),
    starkinfra.IndividualDocument(
        type="selfie",
        content="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIAAD...",
        identity_id='5155165527080960',
        tags=["breaking", "bad"]
    )
])

for document in documents:
    print(document)

Note: Instead of using IndividualDocument objects, you can also pass each element in dictionary format

Query IndividualDocuments

You can query multiple individual documents according to filters.

import starkinfra
from datetime import date

documents = starkinfra.individualidentity.query(
    limit=10,
    after=date(2020, 1, 1),
    before=date(2020, 4, 1),
    status="success",
    tags=["breaking", "bad"],
)

for document in documents:
    print(document)

Get an IndividualDocument

After its creation, information on an individual document may be retrieved by its id.

import starkinfra

document = starkinfra.individualdocument.get("5155165527080960")

print(document)

Query IndividualDocument logs

You can query individual document logs to better understand individual document life cycles.

import starkinfra
from datetime import date

logs = starkinfra.individualdocument.log.query(
    limit=50, 
    after=date(2022, 1, 1),
    before=date(2022, 1, 20),
)

for log in logs:
    print(log)

Get an IndividualDocument log

You can also get a specific log by its id.

import starkinfra

log = starkinfra.individualdocument.log.get("5155165527080960")

print(log)

Webhook

Create a webhook subscription

To create a webhook subscription and be notified whenever an event occurs, run:

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 webhook subscriptions

To search for registered webhook subscriptions, run:

import starkinfra

webhooks = starkinfra.webhook.query()

for webhook in webhooks:
    print(webhook)

Get a webhook subscription

You can get a specific webhook subscription by its id.

import starkinfra

webhook = starkinfra.webhook.get("1082736198236817")

print(webhook)

Delete a webhook subscription

You can also delete a specific webhook subscription by its id.

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.

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:

import starkinfra
from datetime import date

events = starkinfra.event.query(after=date(2020, 3, 20), is_delivered=False)

for event in events:
    print(event)

Get a webhook event

You can get a specific webhook event by its id.

import starkinfra

event = starkinfra.event.get("1082736198236817")

print(event)

Delete a webhook event

You can also delete a specific webhook event by its id.

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.

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.

import starkinfra
from datetime import date

attempts = starkinfra.event.attempt.query(after=date(2020, 3, 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:

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:

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.
