starkbank 2.13.1

SDK to facilitate Python integrations with Stark Bank

Stark Bank Python SDK

Welcome to the Stark Bank Python SDK! This tool is made for Python developers who want to easily integrate with our API. This SDK version is compatible with the Stark Bank API v2.

If you have no idea what Stark Bank is, check out our website and discover a world where receiving or making payments is as easy as sending a text message to your client!

Supported Python Versions

This library supports the following Python versions:

• Python 2.7
• Python 3.4+

Stark Bank 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 starkbank

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 following methods:

2.1. Check out the options in our tutorial.

2.2. Use our SDK:

import starkbank

privateKey, publicKey = starkbank.key.create()

# or, to also save .pem files in a specific path
privateKey, publicKey = starkbank.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 Starkbank 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 starkbank

# 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-----

-----END EC PRIVATE KEY-----
"""

project = starkbank.Project(
    environment="sandbox",
    id="5656565656565656",
    private_key=private_key_content
)

3.2. To create Organization credentials in Sandbox:

3.2.1. Log into Starkbank 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 starkbank

# 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==

IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
"""

organization = starkbank.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
)

# To dynamically use your organization credentials in a specific workspace_id,
# you can use the Organization.replace() function:
starkbank.balance.get(user=starkbank.Organization.replace(organization, "4848484848484848"))

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 argument in all functions:

import starkbank

balance = starkbank.balance.get(user=project)  # or organization

4.2 Set it as a default user in the SDK:

import starkbank

starkbank.user = project  # or organization

balance = starkbank.balance.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 starkbank

starkbank.language = "en-US"

Language options are "en-US" for english and "pt-BR" for brazilian portuguese. English is default.

6. Resource listing and manual pagination

Almost all SDK resources provide a query and a page function.

• The query function provides a straight forward 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 starkbank

for transaction in starkbank.transaction.query(limit=200):
    print(transaction)

• 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 starkbank

cursor = None
while True:
    transactions, cursor = starkbank.transaction.page(limit=50, cursor=cursor)
    for transaction in transactions:
        print(transaction)
    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 Bank, you'll need funds in your account, which can be added to your balance by creating an Invoice or a Boleto.

In the Sandbox environment, most of the created Invoices and Boletos will be automatically paid, so there's nothing else you need to do to add funds to your account. Just create a few Invoices and wait around a bit.

In Production, you (or one of your clients) will need to actually pay this Invoice or Boleto 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(starkbank.boleto.create))

Create transactions

To send money between Stark Bank accounts, you can create transactions:

import starkbank

transactions = starkbank.transaction.create([
    starkbank.Transaction(
        amount=100,  # (R$ 1.00)
        receiver_id="1029378109327810",
        description="Transaction to dear provider",
        external_id="12345",  # so we can block anything you send twice by mistake
        tags=["provider"]
    ),
    starkbank.Transaction(
        amount=234,  # (R$ 2.34)
        receiver_id="2093029347820947",
        description="Transaction to the other provider",
        external_id="12346",  # so we can block anything you send twice by mistake
        tags=["provider"]
    ),
])

for transaction in transactions:
    print(transaction)

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

Query transactions

To understand your balance changes (bank statement), you can query transactions. Note that our system creates transactions for you when you receive boleto payments, pay a bill or make transfers, for example.

import starkbank

transactions = starkbank.transaction.query(
    after="2020-01-01",
    before="2020-03-01"
)

for transaction in transactions:
    print(transaction)

Get a transaction

You can get a specific transaction by its id:

import starkbank

transaction = starkbank.transaction.get("5155165527080960")

print(transaction)

Get balance

To know how much money you have in your workspace, run:

import starkbank

balance = starkbank.balance.get()

print(balance)

Create transfers

You can also create transfers in the SDK (TED/Pix).

import starkbank
from datetime import datetime, timedelta

transfers = starkbank.transfer.create([
    starkbank.Transfer(
        amount=100,
        bank_code="033",  # TED
        branch_code="0001",
        account_number="10000-0",
        tax_id="012.345.678-90",
        name="Tony Stark",
        tags=["iron", "suit"]
    ),
    starkbank.Transfer(
        amount=200,
        bank_code="20018183",  # Pix
        branch_code="1234",
        account_number="123456-7",
        account_type="salary",
        external_id="my-internal-id-12345",
        tax_id="012.345.678-90",
        name="Jon Snow",
        scheduled=datetime.utcnow() + timedelta(days=3)
    )
])

for transfer in transfers:
    print(transfer)

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

Query transfers

You can query multiple transfers according to filters.

import starkbank
from datetime import datetime

transfers = starkbank.transfer.query(
    after=datetime(2020, 1, 1),
    before=datetime(2020, 4, 1)
)

for transfer in transfers:
    print(transfer.name)

Cancel a scheduled transfer

To cancel a single scheduled transfer by its id, run:

import starkbank

transfer = starkbank.transfer.delete("5155165527080960")

print(transfer)

Get a transfer

To get a single transfer by its id, run:

import starkbank

transfer = starkbank.transfer.get("5155165527080960")

print(transfer)

Get a transfer PDF

A transfer PDF may also be retrieved by its id. This operation is only valid if the transfer status is "processing" or "success".

import starkbank

pdf = starkbank.transfer.pdf("5155165527080960")

with open("transfer.pdf", "wb") as file:
    file.write(pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Query transfer logs

You can query transfer logs to better understand transfer life cycles.

import starkbank

logs = starkbank.transfer.log.query(limit=50)

for log in logs:
    print(log.id)

Get a transfer log

You can also get a specific log by its id.

import starkbank

log = starkbank.transfer.log.get("5155165527080960")

print(log)

Query Bacen institutions

You can query institutions registered by the Brazilian Central Bank for Pix and TED transactions.

import starkbank

institution = starkbank.institution.query(search="stark")

for institution in institutions:
    print(institution)

Create invoices

You can create dynamic QR Code invoices to charge customers or to receive money from accounts you have in other banks.

Since the banking system only understands value modifiers (discounts, fines and interest) when dealing with dates (instead of datetimes), these values will only show up in the end user banking interface if you use dates in the "due" and "discounts" fields.

If you use datetimes instead, our system will apply the value modifiers in the same manner, but the end user will only see the final value to be paid on his interface.

Also, other banks will most likely only allow payment scheduling on invoices defined with dates instead of datetimes.

# coding: utf-8
import starkbank
from datetime import date, datetime, timedelta


invoices = starkbank.invoice.create([
    starkbank.Invoice(
        amount=23571,  # R$ 235,71 
        name="Buzz Aldrin",
        tax_id="012.345.678-90", 
        due=datetime.utcnow() + timedelta(hours=1),
        expiration=timedelta(hours=3).total_seconds(),
        fine=5,  # 5%
        interest=2.5,  # 2.5% per month
        tags=["immediate"]
    ),
    starkbank.Invoice(
        amount=23571,  # R$ 235,71 
        name="Buzz Aldrin",
        tax_id="012.345.678-90", 
        due=date(2022, 3, 20),
        expiration=timedelta(hours=3).total_seconds(),
        fine=5,  # 5%
        interest=2.5,  # 2.5% per month
        tags=["scheduled"]
    )
])

for invoice in invoices:
    print(invoice)

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

Get an invoice

After its creation, information on an invoice may be retrieved by its id. Its status indicates whether it's been paid.

import starkbank

invoice = starkbank.invoice.get("5155165527080960")

    file.write(pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Get an invoice QR Code

After its creation, an Invoice QR Code may be retrieved by its id.

import starkbank

qrcode = starkbank.invoice.qrcode("5881614903017472", size= 15)

with open("qrcode.png", "wb") as file:
    file.write(qrcode)

Be careful not to accidentally enforce any encoding on the raw png content, as it may corrupt the file.

Cancel an invoice

You can also cancel an invoice by its id. Note that this is not possible if it has been paid already.

import starkbank

invoice = starkbank.invoice.update("5155165527080960", status="canceled")

import starkbank

pdf = starkbank.invoice.log.pdf("5155165527080960")

with open("invoice-reversal.pdf", "wb") as file:
    file.write(pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Get an invoice payment information

# coding: utf-8
import starkbank
from datetime import datetime


boletos = starkbank.boleto.create([
    starkbank.Boleto(
        amount=23571,  # R$ 235,71 
        name="Buzz Aldrin",
        tax_id="012.345.678-90",

print(log)

Investigate a boleto

You can discover if a StarkBank boleto has been recently paid before we receive the response on the next day. This can be done by creating a BoletoHolmes object, which fetches the updated status of the corresponding Boleto object according to CIP to check, for example, whether it is still payable or not. The investigation happens asynchronously and the most common way to retrieve the results is to register a "boleto-holmes" webhook subscription, although polling is also possible.

import starkbank

holmes = starkbank.boletoholmes.create([
    starkbank.BoletoHolmes(
        boleto_id="5656565656565656",
    ),
    starkbank.BoletoHolmes(
        boleto_id="4848484848484848",
    ),
])

for sherlock in holmes:
    print(sherlock)

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

Get a boleto holmes

To get a single Holmes by its id, run:

import starkbank

sherlock = starkbank.boletoholmes.get("19278361897236187236")

print(sherlock)

Query boleto holmes

You can search for boleto Holmes using filters.

import starkbank

holmes = starkbank.boletoholmes.query(
    tags=["customer_1", "customer_2"]
)

for sherlock in holmes:
    print(sherlock)

Query boleto holmes logs

Searches are also possible with boleto holmes logs:

import starkbank

logs = starkbank.boletoholmes.log.query(
    holmes_ids=["5155165527080960", "76551659167801921"],
)

for log in logs:
    print(log)

Get a boleto holmes log

You can also get a boleto holmes log by specifying its id.

import starkbank

log = starkbank.boletoholmes.log.get("5155165527080960")

print(log)

Pay a BR Code

Paying a BR Code is also simple. After extracting the BRCode encoded in the Pix QR Code, you can do the following:

import starkbank

payments = starkbank.brcodepayment.create([
    starkbank.BrcodePayment(
        brcode="00020126580014br.gov.bcb.pix0136a629532e-7693-4846-852d-1bbff817b5a8520400005303986540510.005802BR5908T'Challa6009Sao Paulo62090505123456304B14A",

        description="this will be fast",
        tags=["pix", "qrcode"],
    )
])

for payment in payments:
    print(payment)

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

Get a BR Code payment

To get a single BR Code payment by its id, run:

import starkbank

payment = starkbank.brcodepayment.get("19278361897236187236")

        tags=["again"],
    ),
])

for payment in payments:
    print(payment)

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

Get a boleto payment

To get a single boleto payment by its id, run:

import starkbank

payment = starkbank.boletopayment.get("19278361897236187236")

import starkbank

pdf = starkbank.boletopayment.pdf("5155165527080960")

with open("boleto-payment.pdf", "wb") as file:
    file.write(pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Delete a boleto payment

You can also cancel a boleto payment by its id. Note that this is not possible if it has been processed already.

import starkbank

payment = starkbank.boletopayment.delete("5155165527080960")

import starkbank

log = starkbank.taxpayment.log.get("1902837198237992")

print(log)

Note: Some taxes can't be payed with bar codes. Since they have specific parameters, each one of them has its own resource and routes, which are all analogous to the TaxPayment resource. The ones we currently support are:

• DarfPayment, for DARFs

Preview payment information before executing the payment

You can preview multiple types of payment to confirm any information before actually paying. If the "scheduled" parameter is not informed, today will be assumed as the intended payment date. Right now, the "scheduled" parameter only has effect on BrcodePreviews. This resource is able to preview the following types of payment: "brcode-payment", "boleto-payment", "utility-payment" and "tax-payment"

# coding: utf-8
import starkbank
from datetime import date, timedelta


previews = starkbank.paymentrequest.create([
    starkbank.PaymentPreview(
        id="00020126580014br.gov.bcb.pix0136a629532e-7693-4846-852d-1bbff817b5a8520400005303986540510.005802BR5908T'Challa6009Sao Paulo62090505123456304B14A",
        scheduled=date.today() + timedelta(days=3)
    ),
    starkbank.PaymentPreview(
        id="34191.09008 61207.727308 71444.640008 5 81310001234321"
    ),
])

for preview in previews:
    print(preview)
    payment = preview.payment
    if preview.type == "brcode-payment":
        print(payment.status)

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

Create payment requests to be approved by authorized people in a cost center

You can also request payments that must pass through a specific cost center approval flow to be executed. In certain structures, this allows double checks for cash-outs and also gives time to load your account with the required amount before the payments take place. The approvals can be granted at our website and must be performed according to the rules specified in the cost center.

Note: The value of the center_id parameter can be consulted by logging into our website and going to the desired cost center page.

# coding: utf-8
import starkbank
from datetime import date, timedelta


requests = starkbank.paymentrequest.create([
    starkbank.PaymentRequest(
        center_id="5967314465849344",
        payment=starkbank.Transfer(
            amount=200,
            bank_code="341",
            branch_code="1234",
            account_number="123456-7",
            tax_id="012.345.678-90",
            name="Bucket Head",
            tags=[]
        ),
        due="2020-11-01"
    ),
])

for request in requests:
    print(request)

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

Query payment requests

To search for payment requests, run:

import starkbank

requests = starkbank.paymentrequest.query(center_id=center_id, limit=10)

for request in requests:
    print(request)

Create a webhook subscription

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

import starkbank

webhook = starkbank.webhook.create(
    url="https://webhook.site/dd784f26-1d6a-4ca6-81cb-fda0267761ec",
    subscriptions=["transfer", "boleto", "boleto-payment", "boleto-holmes", "brcode-payment", "utility-payment", "deposit", "invoice"],
)

print(webhook)

Query webhooks

To search for registered webhooks, run:

import starkbank

webhooks = starkbank.webhook.query()

for webhook in webhooks:
    print(webhook)

Get a webhook

You can get a specific webhook by its id.

import starkbank

webhook = starkbank.webhook.get("10827361982368179")

print(webhook)

Delete a webhook

You can also delete a specific webhook by its id.

import starkbank

webhook = starkbank.webhook.delete("10827361982368179")

print(webhook)

Process webhook events

It's easy to process events that arrived in your webhook. Remember to pass the signature header so the SDK can make sure it's really StarkBank that sent you the event.

import starkbank

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

event = starkbank.event.parse(
    content=response.data.decode("utf-8"),
    signature=response.headers["Digital-Signature"],
)

if event.subscription == "transfer":
    print(event.log.transfer)
    
elif event.subscription == "boleto":
    print(event.log.boleto)
    
elif event.subscription == "boleto-payment":
    print(event.log.payment)

elif event.subscription == "boleto-holmes":
    print(event.log.holmes)

elif event.subscription == "brcode-payment":
    print(event.log.payment)

elif event.subscription == "utility-payment":
    print(event.log.payment)

elif event.subscription == "deposit":
    print(event.log.deposit)

elif event.subscription == "invoice":
    print(event.log.invoice)

Query webhook events

To search for webhooks events, run:

import starkbank

events = starkbank.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.

import starkbank

event = starkbank.event.get("10827361982368179")

print(event)

Delete a webhook event

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

import starkbank

event = starkbank.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 starkbank

event = starkbank.event.update(id="129837198237192", is_delivered=True)

print(event)

Query failed webhook event delivery attempts information

You can also get information on failed webhook event delivery attempts.

import starkbank

attempts = starkbank.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:

import starkbank

attempt = starkbank.event.attempt.get("1616161616161616")

print(attempt)

Get DICT key

You can get the Pix key's parameters by its id.

import starkbank

dict_key = starkbank.dictkey.get("[e-mail]")

print(dict_key)

Query your DICT keys

To take a look at the Pix keys linked to your workspace, just run the following:

import starkbank

dict_keys = starkbank.dictkey.query(status="registered")

for dict_key in dict_keys:
    print(dict_key)

Create a new Workspace

The Organization user allows you to create new Workspaces (bank accounts) under your organization. Workspaces have independent balances, statements, operations and users. The only link between your Workspaces is the Organization that controls them.

Note: This route will only work if the Organization user is used with workspace_id=None.

import starkbank

workspace = starkbank.workspace.create(
    username="iron-bank-workspace-1",
    name="Iron Bank Workspace 1",
    user=organization,
)

print(workspace)

List your Workspaces

This route lists Workspaces. If no parameter is passed, all the workspaces the user has access to will be listed, but you can also find other Workspaces by searching for their usernames or IDs directly.

import starkbank

workspaces = starkbank.workspace.query(limit=30)

for workspace in workspaces:
    print(workspace)

Get a Workspace

You can get a specific Workspace by its id.

import starkbank

workspace = starkbank.workspace.get("10827361982368179")

print(workspace)

Update a Workspace

You can update a specific Workspace by its id.

import starkbank

workspace = starkbank.workspace.update(
    "10827361982368179",
    username="new-username",
    name="New Name",
    allowed_tax_ids=["012.345.678-90"],
)

print(workspace)

Note: the Organization user can only update a workspace with the Workspace ID set.

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 starkbank

try:
    transactions = starkbank.transaction.create([
        starkbank.Transaction(
            amount=99999999999999,  # (R$ 999,999,999,999.99)
            receiver_id="1029378109327810",
            description=".",
            external_id="12345",  # so we can block anything you send twice by mistake
            tags=["provider"]
        ),
    ])
except starkbank.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 starkbank.event.parse() when the provided content and signature do not check out with the Stark Bank public key.
