Close the loop on events the team has retired
When the team uses a deliberate reaction to confirm that an event should be retired, remove it from active tracking-plan use in Amplitude.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Delete Amplitude Event Type
Delete an event type from amplitude. this action allows you to: - remove an event type from your project - mark live events as deleted - remove planned events from the tracking plan key features: - different behavior based on event status (live, planned, etc.) - returns success/failure status
Why this helps
Old event definitions remain confusing when retirement decisions are not carried into the tracking plan.
- Keep the event catalogue closer to current product behavior.
- Reduce ambiguity around obsolete or planned events.
- Turn a deliberate team decision into a clear next step.
Setup
Build it in a few focused steps.
- 1Connect Slack and Amplitude to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to delete or mark an exact Amplitude event type deleted only after a designated reaction confirms retirement.
- 3Choose Slack Message Reaction Added and select a channel for run reports.
- 4Test with one real retirement decision and verify the event status in Amplitude.
Questions about this workflow
Does deletion behave the same for all events?
No. The action behaves differently depending on whether the event is live or planned.
How should the trigger be constrained?
Use a deliberate reaction on the relevant Slack message and name the exact event in the instruction.
