Checkbook API

Project description

Checkbook Python Client

The Checkbook API enables businesses to programmatically send and receive payments using digital checks and other payment methods. With Checkbook, you can automate payment workflows, disburse funds instantly, and manage transactions securely—all without the delays and costs of traditional paper checks.

Requirements.

Python 3.9+

Installation & Usage

pip install

If the python package is hosted on a repository, you can install directly using:

pip install checkbook

Then import the package:

import checkbook

Obtaining Your API Keys

First, log in to your account. Access your Checkbook dashboard via our website app.checkbook.io
Second, navigate to the developer settings. The developer settings page can be found under the Settings -> Developer menu
Third, generate the API keys. Each Checkbook account can have multiple API keys, and each API key can have its own expiration date and name for easier management. A given API key will have two parts: a public key and a secret key.

Publishable Key (Public Key): This is an identifier associated with each key and may be included in emails or support tickets sent to the Checkbook team.

Secret Key (Private Key): This key is private and should never be exposed in client-side code or shared publicly. Treat it like a password.

Webhook Key: This key is used for verifying webhook signatures and ensuring the webhook originated from Checkbook. It can only be viewed after generating an API key.

Please securely save your keys immediately after generation, as we do not provide a way to retrieve your secret key after it has been created. Should you lose your keys, you can always generate a new one.

Environment

Checkbook supports three environments: demo, sandbox, and production.

Each of these environments can be accessed using their respective url: demo.checkbook.io, api.sandbox.checkbook.io, and api.checkbook.io

The demo environment only returns fixed responses, it cannot be used to return any custom requests and only has one set of usable API keys which are public. The demo environment is intended for mimicking production or sandbox responses but does not move real money.
The sandbox environment is used for early development and integration testing. It allows developers to experiment with the API, validate request/response behavior, and build workflows without creating real payments or moving funds. Data in sandbox is isolated and non-production.
The production environment is used for live applications and real payment processing. All API calls in this environment result in actual transactions and should only be used once your integration has been fully tested and approved.

Getting Started

Please follow the installation procedure and then run the following:

import checkbook
from pprint import pprint

from checkbook.api.bank import Bank
from checkbook.api.payment import Payment

# Defining the host is optional and defaults to https://demo.checkbook.io
# See configuration.py for a list of all supported configuration parameters.
configuration = checkbook.Configuration(
    host="https://api.sandbox.checkbook.io",
    api_key={
        "token": "{PUBLIC_KEY_HERE}:{SECRET_KEY_HERE}"
    },
)

# Enter a context with an instance of the API client
with checkbook.ApiClient(configuration) as api_client:
    api_instance = Bank(api_client)
    create_bank_request = {
        "account": "428100001",
        "name": "Checking account",
        "routing": "021000021",
        "type": "CHECKING",
    }  # CreateBankRequest |

    try:
        # Add bank account
        api_response = api_instance.post_bank(create_bank_request)
        pprint(api_response)
        bank_id = api_response.id
        print("Bank Id:", bank_id)

        # Release Microdeposits
        api_instance = Bank(api_client)
        bank_release_request = {"account": bank_id}  # BankReleaseRequest |
        api_instance.post_bank_release(bank_release_request)
        print("Released micro deposits!")

        # Verify Microdeposits - sandbox amounts are always 0.07 and 0.15
        bank_verify_request = {
            "account": bank_id,
            "amount_1": 0.07,
            "amount_2": 0.15,
        }  # BankVerifyRequest |
        api_instance.post_bank_verify(bank_verify_request)
        print("Bank account successfully verified!")

        # Send a payment
        recipient = checkbook.models.CreateDigitalCheckRequestRecipient(
            "dwight@example.com"
        )
        api_instance = Payment(api_client)
        create_digital_check_request = {
            "account": bank_id,
            "name": "Dwight Schrute",
            "amount": 100.0,
            "recipient": recipient,
            "deposit_options": ["BANK"],
        }  # CreateDigitalCheckRequest |

        api_response = api_instance.post_check_digital(create_digital_check_request)
        print("The response of Payment->post_check_digital:\n")
        pprint(api_response)

    except Exception as e:
        print("Exception when running demo script: %s\n" % e)
