Trigger
Message Reaction Added

Action
Get Document Binary
Tool to retrieve the binary content of a document by docset id and document id.
Why this helps
A source file handoff can stall when the request and the go-ahead are separated across busy conversations.
- Make the handoff signal easy to recognize.
- Retrieve the source content from the referenced IDs.
- Reduce reminders to follow up on a file request.
Setup
Build it in a few focused steps.
- 1Connect Slack and Aryn to Notis once through the portal.
- 2Create a named automation and describe the agreed reaction and retrieval outcome in one plain-language prompt.
- 3Choose Message Reaction Added as the trigger and select the reporting channel.
- 4Ensure the reacted-to request contains the Aryn docset ID and document ID.
- 5Test with one real source file request and the agreed reaction.
Questions about this workflow
Does the reaction itself identify the document?
No. The docset ID and document ID need to be available in the reacted-to message or accessible context.
What does Aryn return?
The selected action fetches the binary content of the specified document.
