  title: Circle Developer Platform Admin - Courses Headless - Member API
  description: 'Circle (circle.so) is an all-in-one community platform for creators, coaches, and brands. This description grounds Circle''s documented public developer platform into a single OpenAPI file for discovery. It covers two admin- or member-authenticated REST surfaces: the Admin API V2 (base https://app.circle.so/api/admin/v2) for community administration and automation, and the Headless Member API (base https://app.circle.so/api/headless/v1) for building your own member-facing experience, plus the Headless Auth API token exchange. Admin API requests use an "Authorization: Token AUTH_TOKEN" header; Headless Member API requests use a member-scoped JWT in an "Authorization: Bearer ACCESS_TOKEN" header issued by the Auth API. API access is gated to the Business plan and above. This is the community-software company at circle.so, NOT the USDC / stablecoin financial-services company. Paths shown are a representative, grounded subset of the full reference published at api-headless.circle.so.'
