  title: IBM Cloud IAM Authenticate and Inspect the Calling API Key
  summary: Exchange an API key for an IAM access token, inspect that key, and refresh the token.
  description: >-
    The bootstrap flow for every IBM Cloud integration. Nothing else in IBM Cloud
    can be called until an API key has been exchanged for an IAM access token, so
    this workflow establishes that foundation: it mints an access token from an
    API key, looks the key up by its value to confirm which identity and account
    the caller is actually operating as, and then exercises the refresh grant so a
    long-running integration can renew the token before its one hour lifetime
    expires. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.

  summary: Mint an IAM access token from an API key, identify the key, and refresh the token.
  description: >-
    Trades an API key for an access token using the IBM API key grant, resolves
    the key's identity and account by looking it up by value, and then renews the
    token with the refresh grant.
