Mark Process Street Workflows Complete by Removing Slack Reactions
You completed the work. Remove the reaction from the Slack message. Notis marks the matching workflow run as complete in Process Street. One action closes the loop.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Complete a workflow run
This tool marks an entire workflow run as completed in process street. it updates the workflow run's status to 'completed', distinguishing it from process street complete task which completes individual tasks.
Why this helps
Work gets done but doesn't get marked as complete in Process Street. You forget to go back and close out the workflow, leaving your project status unclear.
- Complete workflows without leaving Slack
- Intuitive signal (removing reaction = task done)
- Reduce context-switching between tools
- Keep Process Street status in sync with Slack reality
Setup
Build it in a few focused steps.
- 1Connect Slack and Process Street to Notis.
- 2Create an automation with the prompt: 'When I remove a reaction from a Slack message, find the matching workflow run in Process Street and mark it as complete.'
- 3Choose 'Message Reaction Removed' as your trigger.
- 4Tell Notis how to match the Slack message to a workflow (e.g., by message text, by thread, or by a workflow ID mentioned in the message).
- 5Test by reacting and then un-reacting a message to confirm the workflow status updates in Process Street.
Questions about this workflow
What if there's no matching workflow run?
Notis will skip the completion and report that no workflow was found. You can refine the matching logic or use message-based workflows instead.
Can I use different reactions to mean different statuses (e.g., remove :hourglass: to complete, remove :question: to mark as blocked)?
Yes. You can set up multiple automations with different reactions, each triggering different Process Street actions (complete, update, etc.).
Does this work in threads or just top-level messages?
It works on any message. Notis will find the associated workflow based on your matching logic.
