Decommission an Algolia index with a Slack reaction
When an index is truly done, deleting it should be deliberate but not a chore. Post the decommission note, and once it is approved, react with your confirmation emoji so Notis permanently removes the named Algolia index.
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 Index
Tool to delete the specified index and all its records. use when you need to permanently remove an index after confirming it's no longer needed.
Why this helps
Dead indices linger forever because deleting them feels risky, so nobody ever gets around to the cleanup and clutter builds up.
- Approved decommissions become a single deliberate reaction.
- Keeps your Algolia account free of dead, unused indices.
- Notis reports the deletion so there is a clear record of it.
Setup
Build it in a few focused steps.
- 1Connect Slack and Algolia to Notis once from the portal.
- 2Create a new automation in the portal Automations screen.
- 3Describe it plainly, for example: when I add the confirm emoji to a decommission message, delete the named Algolia index.
- 4Choose the reaction added trigger, filter it to your confirmation emoji, and set the channel for run reports.
- 5React to a test message that names a throwaway index and confirm it is removed.
Questions about this workflow
Is deleting an index reversible?
No. Deleting an index permanently removes it and all its records, so reserve a distinct confirmation emoji and only use it after a real decision.
Can I require the message to name the index?
Yes. Have the decommission message state the index name so the reaction acts on exactly the index you intend.
