Notes

  • The bot must be a member of a private channel before it can act there (Slack answers not_in_channel otherwise).
  • Slack rate-limits each Web API method on its own tier; a throttled call fails with the number of seconds to wait and is safe for the node's retry policy to repeat.
  • A trigger_id expires three seconds after the interaction, so this node has to be the first step of an interaction-triggered workflow, not a later one.
  • Slack returns the failing field paths when a view payload is malformed; they are included in the error message.

See Open Modal run in a workflow.

In a technical demo we add the Slack connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
