Keep shared event links in step with calendar updates
When the event details move, Notis can refresh the matching Dub link so people reach the current destination.
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
Upsert a Link
Tool to create or update a short link in Dub. Use when you need to create a new short link or update an existing one. If the link already exists (matching domain and key), it will be updated; otherwise, a new link will be created.
Why this helps
A changed event URL can leave an old short link pointing attendees to stale information.
- Refresh an existing short link when an event is modified.
- Use a stable key pattern to match the calendar event to its Dub link.
- Reduce the chance that shared links point to outdated event details.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Dub once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3In one instruction, tell Notis how to match the event to its Dub link and provide the updated destination URL pattern.
- 4Pick the Event Updated trigger and choose where run reports should go.
- 5Test with one real event update and verify the matching link in Dub.
