  title: Workato Publish and Verify an Event Message
  summary: Publish a message to a topic, then long-poll to consume it back.
  description: >-
    A round-trip validation of an event topic. The workflow publishes a single
    message to the topic, captures its message ID, and then consumes from the
    topic with long polling using that message ID as the cursor — confirming
    the published message can be read back. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
