Refresh a launched ImageKit asset from Slack
When a team marks a specific asset ready, let Notis request a cache purge so the updated version can reach viewers.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Purge ImageKit Cache
Tool to purge CDN and ImageKit caches for a given URL. Use when you need to invalidate cached content on ImageKit.
Why this helps
A launch can be delayed when a refreshed image is ready but nobody remembers to invalidate its cached URL.
- Connects a deliberate launch signal to the cache refresh request.
- Reduces the chance of serving a stale visual after an update.
- Keeps the release step inside the launch conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and ImageKit io to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to create one in plain language.
- 3In one instruction, ask Notis to purge the ImageKit URL only when the designated launch reaction is added to a message that names the URL.
- 4Choose the message-reaction-added Slack trigger and a channel for run reports.
- 5Test with a known non-critical asset URL and review the purge result.
Questions about this workflow
Does the reaction edit the image?
No. It requests a cache purge for the URL in the message.
What should the message include?
Include the exact ImageKit URL and use the chosen reaction only when the updated asset is ready.
