Remove a product from a set when approval is withdrawn
If a team reverses a product-set decision in Slack, Notis can remove that product from the named Vision ProductSet.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Remove Product from ProductSet
Tool to remove a Product from a specified ProductSet. Use after creating both resources in the same project/location to unlink a product from its set.
Why this helps
Reversed decisions can leave stale catalog membership when the original update is easier to make than to undo.
- Keep set membership aligned with a withdrawn decision.
- Use the reaction removal as an explicit follow-up signal.
- Reduce stale entries that confuse later reviews.
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Cloud Vision to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to unlink a product when an approval reaction is removed from Slack.
- 3Describe in one instruction how the message identifies the product and ProductSet and what removal means.
- 4Choose the Slack reaction-removed trigger, a report channel, and test with one real reversal.
Questions about this workflow
Does this delete the product?
No. It removes the product from a ProductSet; the Product resource remains.
What if the reaction was removed accidentally?
Make the instruction specific about the approval convention and review the run report for each change.
