Buy Me a Coffee Supporters API

openapi: 3.2.0
info:
  title: Buy Me a Coffee Extras Supporters API
  description: 'The Buy Me a Coffee API is a read-only REST interface that gives a creator programmatic access to their own account data on Buy Me a Coffee - a creator-support platform for tips, memberships, and shop purchases. Authentication uses a personal access Bearer token created self-serve in the Developer Dashboard (log in with a regular Buy Me a Coffee account, then Create New Token; a read-only option is available). Add `Authorization: Bearer <token>` to every request. The API returns paginated collections (Laravel-style pagination with current_page, per_page, next_page_url, total, etc.) and exposes one-time supporters, memberships/subscriptions, and Extras purchases.

    NOTE ON MODELING: Buy Me a Coffee does not publish a machine-readable OpenAPI document publicly (the reference sits behind the Developer Dashboard login). The collection endpoints and query parameters here (/subscriptions with status, /supporters, /extras, all paginated) are confirmed from the developer docs, community wrappers, and the Microsoft Power Platform connector. The single-resource by-ID paths (/subscriptions/{id}, /supporters/{id}, /extras/{id}) are honestly modeled from the documented "get by ID" operations; the exact URL templates are inferred, not quoted verbatim, and are marked with x-endpoint-modeled.'
