Use a Slack reaction to cue Box watermarking
A reaction can be a quick shorthand for a next step. Let a designated Slack reaction cue a watermark on the Box file named in the message.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Apply watermark to file
Applies or update a watermark on a file.
Why this helps
A lightweight review signal is easy to miss, and the corresponding document handling step gets delayed.
- Turn a consistent emoji signal into a Box document action.
- Reduce extra messages to request routine handling.
- Make the review handoff quicker to recognize.
Setup
Build it in a few focused steps.
- 1Connect Slack and Box to Notis once through the portal.
- 2Create an automation and describe which reaction should apply a watermark to the Box file discussed in the message.
- 3Choose the message reaction added trigger and specify the reaction, file identification guidance, and watermark behavior in the prompt.
- 4Choose a run-report channel and test by adding the designated reaction to a real file discussion.
Questions about this workflow
Can the trigger be limited to one reaction?
The trigger supports optional filtering by channel and emoji name; describe the intended signal in the automation prompt too.
What if the message does not identify a Box file?
Ask Notis to skip the action unless it can confidently identify the file.
