Send a delayed response to a user’s slash command. Delayed responses should be used if your flow runtime is greater than three seconds. Slash commands are submitted in the message box in Slack, though they are technically not messages. They cause a payload of data to be sent from Slack to an app.

This action should be paired with a Slash Command event.

Unless otherwise indicated, field types are text.


  • Command
    • Response URL: URL for response
    • Message Text_: content of the message to send to the user
    • Response Type (drop-down): visibility of the response (Visible to Channel or Visible to User)
    • Attachments (object): JSON code formatted according to the Slack API documentation
