Keep expense review events current
When expense details change, send the updated context to Notis and patch the existing review 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
A review meeting can keep outdated context after expense amounts, vendors, or review notes change.
- Update only event fields named in the instruction.
- Keep the review event aligned with revised information supplied to Notis.
- Avoid replacing the whole event when only specified details need changing.
Setup
Build it in a few focused steps.
- 1Connect Altoviz and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for expense review updates.
- 3Tell Notis to find the specified existing event and patch only the details included in the webhook request.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real event and confirm the changed fields.
Questions about this workflow
Does this workflow discover expense changes on its own?
No built-in Altoviz triggers are listed. An external caller must send a webhook request when the update should be handled.
Will omitted event fields be cleared?
Patch semantics update the specified fields. If you provide an array such as attendees, the provided array replaces the existing array.
