Convert large reports without holding up the team
When a Slack post identifies a large report for publication, start an off-thread Heyzine conversion and keep the team updated.
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
Create Flipbook Asynchronously
Tool to create a flipbook asynchronously. Use when converting large documents off-thread; poll for updates on conversion state.
Why this helps
Large files can interrupt focus when someone has to wait around for a conversion to finish.
- Move large document conversion off-thread.
- Keep a Slack record of the report link and conversion status.
- Reduce pressure to stay focused on a single publishing task.
Setup
Build it in a few focused steps.
- 1Connect Slack and Heyzine to Notis once through the portal.
- 2Ask Notis in plain language to start an asynchronous Heyzine conversion for large report URLs shared for publication in Slack and report conversion updates.
- 3Pick Channel Message Received as the trigger and choose a run-report channel.
- 4Test with one real large report URL and review the reported conversion state.
Questions about this workflow
Why use asynchronous conversion here?
The action is intended for large documents converted off-thread, with conversion state polled for updates.
Will the flipbook link be immediate?
The workflow should report progress because asynchronous conversion may not return a finished flipbook immediately.
