Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Remove attendee from event

Why this helps
Calendar attendees remain on invitations after project roles or access decisions change.
- Align invitations with documented decisions
- Reduce stale access
- Avoid manual attendee edits
Setup

- 3Tell Notis to remove a named attendee only when BrainGraph explicitly records the change and the event is unambiguous.
- 4Choose the webhook trigger and report channel.
- 5Test with one event and one confirmed access change.
