Revoke session access codes when plans change
Keep access lists aligned with a changed session plan by removing the code that should no longer be used.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
Action
Delete Access List Item
Tool to delete one or more codes from an access list. Use after confirming the list exists.
Why this helps
Canceled plans can leave old access codes active when nobody remembers the separate cleanup task.
- Connect changed session plans with access cleanup.
- Reduce lingering codes after a cancellation.
- Use explicit list and code details to guide removal.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and ClassMarker once in the Notis portal.
- 2Create an automation in Automations, New Automation, and provide a name and prompt.
- 3Ask Notis in one instruction to remove the specified code from the confirmed access list when the event is updated to cancellation, supplying the list ID and code.
- 4Choose Event Updated and choose where run reports should go.
- 5Test with one real cancellation update and confirm the intended code was removed.
Questions about this workflow
Does Event Updated trigger only for cancellations?
No. State in the prompt that the access code should be removed only when the event update indicates cancellation.
Does the trigger provide a ClassMarker access list ID?
No. Supply the confirmed list ID and exact access code to remove.
