Keep transaction follow-ups current
When status changes, update the event you already rely on so it reflects the latest available information.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Patch Event
Updates specified fields of an existing event in a google calendar using patch semantics (array fields like `attendees` are fully replaced if provided); ensure the `calendar id` and `event id` are valid and the user has write access to the calendar.
Why this helps
An outdated follow-up event can prompt unnecessary checking or leave stale transaction details in view.
- Refresh an existing event after a relevant status update.
- Keep a single follow-up event current when it can be matched reliably.
- Reduce stale reminders after transaction progress changes.
Setup
Build it in a few focused steps.
- 1Connect Blocknative and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Describe how to identify the existing event and patch it with the new status, using only available details.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real update and a known matching calendar event.
Questions about this workflow
Does Patch Event create a new event when no match exists?
No. Patch Event updates an existing event. Instruct Notis to report or skip when it cannot identify a valid event and event ID.
Can the workflow change the event time?
Yes, if the update provides a valid time or your instruction defines one, and the event can be identified.
