info:
  title: Flexpa Access Tokens API
  description: Flexpa lets applications connect a patient to their health insurance plan and retrieve claims and clinical data as normalized FHIR R4 resources. Patients authorize access through Flexpa Link using OAuth 2.0 with PKCE, producing a Patient Access Token. Server-to-server Application Access Tokens are minted with the client_credentials grant using publishable and secret keys. The FHIR API is served under https://api.flexpa.com/fhir.

      summary: Exchange a code, refresh a token, or mint an Application Access Token
      description: The token endpoint supports the authorization_code grant (with PKCE code_verifier) to obtain a Patient Access Token, the refresh_token grant to renew it, and the client_credentials grant (Basic auth with publishable_key:secret_key) to mint a server-to-server Application Access Token. Application Access Tokens are JWTs signed with ES256 and live for 30 minutes.
