Python wrapper around the new Paddle Billing API

Paddle Classic vs Paddle Billing

• Paddle Classic is the original Paddle API, which is still in use by many merchants. More info can be found here
  • If you are looking for the Paddle Classic API wrapper, please see paddle-client
• Paddle Billing is the new API, which is just launched at 2023, August. Paddle Billing is a complete rewrite of the Paddle Classic API, and is designed to be more flexible and easier to use. More info can be found here

Django Integration

• For Paddle Classic, there is a Django integration available at dj-paddle and django-paddle
• For Paddle Billing, there is a Work In Progress Django integration available at django-paddle-billing

Usage

from paddle_billing_client.client import PaddleApiClient
from apiclient import HeaderAuthentication


client = PaddleApiClient(
    base_url="https://sandbox-api.paddle.com", 
    authentication_method=HeaderAuthentication(token="your-paddle-token")
)

# Create a product
product = client.create_product(
            ProductRequest(
                name="Test Product New",
                tax_category="standard",
                description="Test Product Description",
                image_url="https://example.com/image.png",
                custom_data=dict(foo="bar"),
            )
        )
                         
# Get all products
products = client.list_products()

# Get all prices
plans = client.list_prices()

# Pagination
from paddle_billing_client.pagination import paginate
from paddle_billing_client.models.notification import NotificationQueryParams

for notification in paginate(client.list_notifications, query_params=NotificationQueryParams(
        status="delivered",
        after='ntf_01hb1n6nw8yx1wwts2cyh632s9',
        per_page=10
    )):
        # Process notifications page by page
        print("Notification:")
        print(len(notification.data))
        print(notification.data[-1].id)

Debugging

To print the raw exception response, you can use the VerboseErrorHandler:

from paddle_billing_client.client import PaddleApiClient
from apiclient import HeaderAuthentication
from paddle_billing_client.errors import VerboseErrorHandler

client = PaddleApiClient(
    base_url="https://sandbox-api.paddle.com", 
    authentication_method=HeaderAuthentication(token="your-paddle-token"),
    error_handler=VerboseErrorHandler
)

• Sandbox API url: https://sandbox-api.paddle.com/
• Live API url: https://api.paddle.com/

More usage examples can be found in tests.

Helper functions

from paddle_billing_client.helpers import validate_webhook_signature

# Validate webhook signature
is_valid = validate_webhook_signature(
    signature_header=request.headers.get("HTTP_PADDLE_SIGNATURE"),
    raw_body=request.data,
    secret_key="your-paddle-secret-key",
)

Makefile usage

Makefile contains a lot of functions for faster development.

1. Download and remove Poetry

To download and install Poetry run:

make poetry-download

To uninstall

make poetry-remove

2. Install all dependencies and pre-commit hooks

Install requirements:

make install

Pre-commit hooks coulb be installed after git init via

make pre-commit-install

3. Codestyle

Automatic formatting uses pyupgrade, isort and black.

make codestyle

# or use synonym
make formatting

Codestyle checks only, without rewriting files:

make check-codestyle

Note: check-codestyle uses isort, black and darglint library

Update all dev libraries to the latest version using one comand

make update-dev-deps

4. Code security

make check-safety

This command launches Poetry integrity checks as well as identifies security issues with Safety and Bandit.

make check-safety

5. Type checks

Run mypy static type checker

make mypy

6. Tests with coverage badges

Run pytest

make test

7. All linters

Of course there is a command to rule run all linters in one:

make lint

the same as:

make test && make check-codestyle && make mypy && make check-safety

8. Docker

make docker-build

which is equivalent to:

make docker-build VERSION=latest

Remove docker image with

make docker-remove

More information about docker.

9. Cleanup

Delete pycache files

make pycache-remove

Remove package build

make build-remove

Delete .DS_STORE files

make dsstore-remove

Remove .mypycache

make mypycache-remove

Or to remove all above run:

make cleanup

📈 Releases

You can see the list of available releases on the GitHub Releases page.

We follow Semantic Versions specification.

We use Release Drafter. As pull requests are merged, a draft release is kept up-to-date listing the changes, ready to publish when you’re ready. With the categories option, you can categorize pull requests in release notes using labels.

List of labels and corresponding titles

Label	Title in Releases
enhancement, feature	🚀 Features
bug, refactoring, bugfix, fix	🔧 Fixes & Refactoring
build, ci, testing	📦 Build System & CI/CD
breaking	💥 Breaking Changes
documentation	📝 Documentation
dependencies	⬆️ Dependencies updates

You can update it in release-drafter.yml.

GitHub creates the bug, enhancement, and documentation labels for you. Dependabot creates the dependencies label. Create the remaining labels on the Issues tab of your GitHub repository, when you need them.

Building and releasing your package

Building a new version of the application contains steps:

• Bump the version of your package poetry version <version>. You can pass the new version explicitly, or a rule such as major, minor, or patch. For more details, refer to the Semantic Versions standard.
• Make a commit to GitHub.
• Create a GitHub release.
• And... publish 🙂 poetry publish --build

🚀 Package Template Features

Development features

• Supports for Python 3.7 and higher.
• Poetry as the dependencies manager. See configuration in pyproject.toml and setup.cfg.
• Automatic codestyle with black, isort and pyupgrade.
• Ready-to-use pre-commit hooks with code-formatting.
• Type checks with mypy; docstring checks with darglint; security checks with safety and bandit
• Testing with pytest.
• Ready-to-use .editorconfig, .dockerignore, and .gitignore. You don't have to worry about those things.

Deployment features

• GitHub integration: issue and pr templates.
• Github Actions with predefined build workflow as the default CI/CD.
• Everything is already set up for security checks, codestyle checks, code formatting, testing, linting, docker builds, etc with Makefile. More details in makefile-usage.
• Dockerfile for your package.
• Always up-to-date dependencies with @dependabot. You will only enable it.
• Automatic drafts of new releases with Release Drafter. You may see the list of labels in release-drafter.yml. Works perfectly with Semantic Versions specification.

Open source community features

• Ready-to-use Pull Requests templates and several Issue templates.
• Files such as: LICENSE, CONTRIBUTING.md, CODE_OF_CONDUCT.md, and SECURITY.md are generated automatically.
• Stale bot that closes abandoned issues after a period of inactivity. (You will only need to setup free plan). Configuration is here.
