Keep calendar event details current
Send an update from Backendless and have Notis apply the requested changes to the matching event.
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
When event details change in your system, the calendar can keep showing outdated information.
- Apply changes to an existing event.
- Use patch semantics to update specified fields.
- Reduce manual calendar maintenance.
Setup
Build it in a few focused steps.
- 1Connect Backendless and Google Calendar once in the Notis portal.
- 2Create a named automation in Automations, New Automation.
- 3In one instruction, explain how each update identifies its Google Calendar event and which changes to apply.
- 4Select a webhook trigger and choose a report channel.
- 5Test with one real update and verify the changed event details.
Questions about this workflow
What is needed to identify the event?
The request needs enough information to identify the intended event, such as its event ID and calendar ID, or other reliable details Notis can use.
Will omitted fields be cleared?
Patch Event updates only specified fields. If you provide an array such as attendees, that array is replaced in full.
