description: >-
  FlowAccount Open API uses OAuth 2.0 client credentials. A registered integration
  exchanges its client_id + client_secret at the token endpoint ({base}/token) with
  grant_type=client_credentials and scope=flowaccount-api to obtain a bearer access
  token, then sends it as `Authorization: Bearer <token>` on every request. Sandbox
  and Production credentials are issued separately on registration. Evidence:
  flowaccount/open-api apps/api/flowaccount-webhook (AuthenticationService.ts, env.json)
  documents grant_type=client_credentials, scope=flowaccount-api, and a tokenPost flow;
  the OpenAPI declares the resulting bearer scheme.
