  title: Fintecture Mint Token then Initiate Payment
  summary: Mint a client-credentials access token, open a payment session, and read its status.
  description: >-
    The full authenticate-then-pay flow. It mints a PIS access token via the
    OAuth client_credentials grant, uses that bearer token to create an Immediate
    Transfer payment session, and reads the resulting payment back to surface its
    connect URL and lifecycle status. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    descriptions.
