  title: Airbyte Bootstrap an Application and Access Token
  summary: Create an API application to mint client credentials, read it back, then exchange those credentials for a bearer access token.
  description: >-
    The credential bootstrap flow for the Airbyte API. It creates an
    Application, which returns a clientId and clientSecret, reads the
    application back by id to confirm it persisted, and then exchanges the
    client credentials for a bearer access token that can be used to authorize
    subsequent API calls. Every step inlines its request so the flow can be
    read and executed without opening the underlying OpenAPI description.
