extend-python

Python library for the Extend API

A Python client for the Extend API, providing a simple and intuitive interface for managing virtual cards, transactions, and more.

Features

• Create and manage virtual cards
• Handle recurring card operations
• Track transactions
• Expense management

Installation

From PyPI

pip install paywithextend

From Source

git clone https://github.com/paywithextend/extend-python.git
cd extend-python
pip install -e .

Quick Start

import asyncio
from extend import ExtendClient
from extend.auth import BasicAuth


async def main():
    # Initialize the client
    client = ExtendClient(
        auth=BasicAuth(
            "your-api-key",
            "your-api-secret",
        )
    )

    # Get all virtual cards
    response = await client.virtual_cards.get_virtual_cards()
    print("Virtual Cards:", response["virtualCards"])

    # Get all transactions
    response = await client.transactions.get_transactions()
    print("Transactions:", response["report"]["transactions"])


# Run the async function
asyncio.run(main())

Using Custom Authorization

Both ExtendClient and APIClient accept reusable authorization strategies defined in extend.auth, enabling scenarios like JWT-based access or shared credentials across clients.

from extend import ExtendClient
from extend.auth import BearerAuth

auth = BearerAuth(jwt_token="your-jwt-token")
client = ExtendClient(auth=auth)

If you want to work with the lower-level APIClient directly, you can pass any Authorization implementation:

from extend.auth import BasicAuth
from extend.client import APIClient

api_client = APIClient(auth=BasicAuth("your-api-key", "your-api-secret"))

Environment Variables

The following environment variables are required for integration tests and examples:

• EXTEND_API_KEY: Your Extend API key
• EXTEND_API_SECRET: Your Extend API secret
• EXTEND_TEST_RECIPIENT: Email address for test card recipient
• EXTEND_TEST_CARDHOLDER: Email address for test cardholder

Development Setup

1. Clone the repository:

   git clone https://github.com/paywithextend/extend-python.git
   cd extend-python
   

2. Create and activate a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   

3. Install development dependencies:

   pip install -e ".[dev]"
   

4. Run tests:

   # Run all tests
   pytest
   
   # Run only unit tests
   pytest tests/test_client.py
   
   # Run only integration tests
   pytest tests/test_integration.py
   

Testing

The project includes both unit tests and integration tests:

• Unit tests (tests/test_client.py): Test the client's internal logic and validation
• Integration tests (tests/test_integration.py): Test actual API interactions
• Example notebook (notebooks/api_testing.ipynb): Interactive examples

To run integration tests, make sure you have set up the required environment variables.
