Notis

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.
