  title: Bubble Initialize Then Trigger a Backend Workflow
  summary: Run the one-time detection call for a backend workflow, then trigger it with the same parameters.
  description: >-
    The build-and-run pattern for the Bubble Workflow API. While building a
    backend workflow, Bubble uses a one-time initialize call to inspect the
    request body and detect the parameter contract. This workflow performs that
    detection call and then triggers the workflow with the same parameter map,
    demonstrating the full setup-to-invocation sequence. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Detect a workflow's parameter contract, then trigger it.
  description: >-
    Posts the parameter map to the initialize endpoint to define the contract,
    then triggers the workflow with the same parameters.
