Steps

Once connected (see setup above), use the Slack tool:

  1. Define the trigger and message content: "After completing the weekly report, send it to #leadership"
  2. OpenClaw composes and sends the message at the right time
  3. Configure recurring sends: "Send this summary every Monday at 9am"
  4. Monitor delivery and adjust the message content as needed

Tips

  • Use Slack messaging as the delivery step in any automated reporting or monitoring workflow
  • Ask OpenClaw to send different versions of a message to different channels — summary to #general, detail to the team channel
  • Include a timestamp or report date in automated messages for easy reference
