Update Chaser invoices when Drive billing records change
When an approved billing record changes, Notis can apply the stated correction to the identified invoice in Chaser, helping changes make it through to the system of record.
Trigger
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Action
Update Invoice
Tool to update an existing invoice's information using its unique identifier. use after confirming the invoice exists when you need to modify fields like status, amounts, or dates.
Why this helps
A correction in a billing document can be missed when invoice updates require a separate manual pass in Chaser.
- Reduce missed invoice corrections
- Use the revised Drive record as the change signal
- Keep invoice updates tied to an identifiable existing record
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Chaser once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Describe in one instruction how to update an existing Chaser invoice from an approved revised billing record, only when the document identifies the invoice and changes.
- 4Pick the Google Drive File Updated trigger and choose where run reports go.
- 5Test with one real revised record that clearly identifies an existing invoice.
Questions about this workflow
What information should the revised record include?
It should clearly identify the existing invoice and state the approved changes. Notis cannot infer missing invoice identifiers or a prior value that the connected apps do not provide.
Will every file update change an invoice?
Your instruction should limit updates to approved billing record changes that identify the invoice and specify what changed. Test with one real example.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Chaser. A trigger fires from one place; an action lands in another.
Google Drive triggers
Chaser actions
Recurring trigger

Get Organization

File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
