Upload Slack images when they are approved
A familiar reaction can tell Notis an image is ready to host, so the approval does not become another task to remember.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Upload Image to ImgBB
Tool to upload an image to ImgBB. Use when you need to host an image and get back its URLs immediately.
Why this helps
Approved assets can stall because the person who gives the go-ahead and the person who uploads them are different.
- Turn an existing approval signal into the next step.
- Separate ready-to-share assets from drafts.
- Give the team a hosted URL after approval.
Setup
Build it in a few focused steps.
- 1Connect Slack and ImgBB to Notis once in the portal.
- 2Create an automation or tell Notis to upload an image when its Slack message receives your chosen approval reaction.
- 3Select Message Reaction Added and name the reaction and relevant channel in the prompt.
- 4Choose a run-report channel and test by reacting to a message with an image.
Questions about this workflow
Can I choose which reaction means approved?
Yes. State the emoji name in the plain-language instruction and use the matching trigger filter if available.
What if the reacted-to message has no image?
Tell Notis to upload only when the original message contains an image.
