  title: Salesforce Marketing Cloud Enter a Contact into a Journey
  summary: Authenticate, find a published journey, inspect it, then fire an entry event.
  description: >-
    A Journey Builder orchestration pattern for Marketing Cloud. The workflow
    obtains an OAuth 2.0 access token, lists published journeys to locate a
    journey to drive, reads that journey's detail to confirm its configuration,
    then fires a journey entry event that injects a contact into the journey at
    its event-triggered entry source. The Marketing Cloud REST description does
    not expose operations to create or publish a journey, so this workflow
    operates against an existing published journey and focuses on the
    discover-inspect-enter cycle. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
