Turn a reaction change into an order correction
If your team uses reaction removal to signal that a request was withdrawn, Notis can carry that correction into an eligible order cancellation.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Cancel and Refund Audio File
Tool to cancel an ordered audio file and issue a refund if applicable. use when no transcription work has been done on the file (pre-processing, audio processing, error states).
Why this helps
A withdrawn request can be easy to miss when the order has already moved into another tool.
- Reflect a withdrawn request without a separate manual handoff.
- Keep cancellation tied to the original Slack order discussion.
- Request a refund when the order qualifies.
Setup
Build it in a few focused steps.
- 1Connect Slack and CastingWords to Notis once through the portal.
- 2Create an automation that explains which reaction removal means an order was withdrawn.
- 3Select the Slack reaction-removed trigger and choose a run-report channel.
- 4Test on a real order discussion where the identified order has had no work done.
Questions about this workflow
Should every removed reaction cancel an order?
Use this only for a deliberate team convention and describe it clearly in the prompt.
Can the workflow cancel an order after work starts?
The action is intended for orders with no transcription work done.
