Make urgent attendee issues visibly acknowledged
Your support workflow sends Notis the Slack message reference and Eventbrite context, and Notis adds a consistent reaction so the team knows the issue has been seen.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Urgent attendee problems can attract duplicate effort or no effort when ownership is unclear.
- Signal receipt without another message
- Reduce duplicate responses
- Make urgent event support easier to scan
Setup
Build it in a few focused steps.
- 1Connect Eventbrite and Slack to Notis once.
- 2Create a new automation and select an incoming webhook trigger.
- 3Write one prompt asking Notis to add a chosen acknowledgment reaction to the referenced Slack message for an urgent Eventbrite issue.
- 4Choose the channel for run reports.
- 5Test with one real test message and its timestamp.
Questions about this workflow
What must the webhook include?
It should provide the Slack channel and message timestamp, plus enough Eventbrite context for Notis to validate the request.
Does the reaction assign an owner?
No. It confirms acknowledgment; your team's reaction convention can indicate the next expected step.
