Buy Me a Coffee is a creator-support platform that lets fans tip creators ("buy a coffee"), subscribe to recurring memberships, and buy extras from a creator's shop. Its developer API is a read-only REST interface (base https://developers.buymeacoffee.com/api/v1) authenticated with a personal access Bearer token created self-serve in the Developer Dashboard. The API exposes a creator's own one-time supporters, memberships/subscriptions, and extra purchases, and the platform also delivers server-push webhooks for donation, membership, and shop events. Buy Me a Coffee charges a flat 5% platform fee on transactions with no monthly fee.
