Why this helps
Approved wording gets copied and reformatted by hand, creating extra steps and possible inconsistencies.
- Use a clear reaction as a readiness signal.
- Reduce copy-and-paste formatting work.
- Keep a formatted version of the approved wording.
Setup
Build it in a few focused steps.
- 1Connect Slack and Customjs to Notis once.
- 2Create an automation in the portal or ask Notis in plain language.
- 3Instruct Notis to format the reacted-to message as a PDF when the agreed approval reaction is added.
- 4Choose the Slack reaction-added trigger and choose a channel for run reports.
- 5Test by adding the chosen reaction to one suitable message and review the PDF.
Questions about this workflow
Does the reaction itself prove formal approval?
Use a reaction only if your team has agreed what it means; the workflow follows the instruction you provide.
Will a reaction on any message create a PDF?
The plain-language instruction should limit the workflow to the intended kind of content and approval reaction.
