Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Get Gamma File URLs
Retrieve generation status and file urls. poll this endpoint every ~5 seconds until status is 'completed'. docs: https://developers.gamma.app/reference/get-gamma-file-urls
Why this helps
A pending deck can become one more thing to remember when the request remains buried in a conversation.
- Use a visible reaction to request a status check
- Keep the source request close to the returned links
- Reduce repeated manual checking
Setup
Build it in a few focused steps.
- 1Connect Slack and Gamma to Notis once through the portal.
- 2Create an automation named Gamma Completion Check.
- 3Describe in one plain-language instruction that Notis should use the generation identifier in a reacted-to Slack message to retrieve Gamma status and file URLs, polling about every five seconds until completed.
- 4Choose the Slack message reaction added trigger, set an appropriate emoji if available, and select a report channel.
- 5Test by reacting to one real message that contains a valid Gamma generation identifier.
Questions about this workflow
What should the Slack message contain?
Include the Gamma generation identifier in the message so Notis can check the right generation.
Can I choose which reaction starts the check?
The Slack reaction trigger supports optional emoji filtering; choose the reaction your team will use if that option is available.
