Bring Gamma file links into the Slack discussion
Use a generation identifier shared in Slack to check status and retrieve the resulting Gamma file URLs.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
People can lose time searching for a presentation link when the request and generated file end up in different places.
- Keep file retrieval close to the request
- Check generation status in the same follow-up flow
- Reduce manual searching for deck links
Setup
Build it in a few focused steps.
- 1Connect Slack and Gamma to Notis once through the portal.
- 2Create a new automation called Gamma File Link Request.
- 3Write one plain-language instruction asking Notis to retrieve status and file URLs for the Gamma generation identifier included in a channel request, polling about every five seconds until completed.
- 4Select the Slack channel message trigger and a channel for run reports.
- 5Test with one real request that includes a valid Gamma generation identifier and confirm the retrieved links.
Questions about this workflow
Can it find a generation without an identifier?
The request should include the generation identifier so Notis can retrieve the matching status and file URLs.
What happens while a generation is still processing?
The Gamma action documentation recommends checking again about every five seconds until the generation is completed.
