info:
  title: Flexpa Access Tokens Claims Data 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.
