Python SDK changelog

Regenerated the Python SDK to incorporate latest API documentation improvements. See July 28, 2026 for more information.

Added OAuth2 client-credentials support. Pass client_id/client_secret instead of api_key and the SDK handles the token exchange and refresh automatically:

1
client = payabli(
2
    client_id="...",
3
    client_secret="...",
4
    environment=payabliEnvironment.SANDBOX,
5
)

The existing api_key-based constructor still works unchanged — no action needed if you’re not switching auth methods. See the Python SDK guide and Authentication to compare both methods.

Changed the VendorQueryRecord.additional_data type from typing.Optional[typing.Dict[str, typing.Dict[str, typing.Any]]] to typing.Optional[typing.Dict[str, str]] to match the API.

As part of an ongoing effort to improve the consistency and usability of our SDKs, we’ve updated the SDK generation process. This update introduces breaking changes to the SDK. All breaking changes affect only method signatures and namespacing, not core record types or properties. SDK initialization, configuration, business logic, and workflows remain unchanged. For more information on precise method signatures and example usage, please see the SDK reference on GitHub.
