Trigger
Message Reaction Added

Action
Execute ClickHouse Query

Why this helps
Approved analytics requests still wait in an informal queue for someone to run them.
- Make approval status visible
- Reduce forgotten analytics requests
- Keep execution tied to the original message
Setup
Build it in a few focused steps.
- 1Connect Slackbot and ClickHouse in Notis once.
- 2Create the automation and describe the approved request format.
- 3Tell Notis which reaction means approved and how to extract the query request from the message.
- 4Pick Message Reaction Added as the trigger.
- 5Choose the report channel and test by approving one real request.
Questions about this workflow
Which reaction should be used?
Choose one team convention, such as a check mark, and state it in the automation prompt.
What if the message has no executable request?
Tell the automation to report that the request needs clarification instead of guessing SQL.
