  title: Salesforce Experience Cloud Feed Post and Comment
  summary: Post a feed element to a community, read it back, and comment on it.
  description: >-
    A community engagement flow built on the Connect REST API. The workflow
    publishes a feed element (post) against a parent record in an Experience
    Cloud site, retrieves the created feed element, then adds a comment to it.
    Each step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
