Keep a readable record of Drive sharing changes
When a file is shared, give the project a simple record of what changed and where to review it.
Trigger
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.
Action
Create Document in Vault
Tool to create a new document in a Basecamp vault. Use when you need to publish a document in a specific project vault with title, HTML content, and optional publication status.
Why this helps
New sharing permissions can be overlooked when access changes happen outside the project workspace.
- Make new sharing changes visible to project owners.
- Keep access context near project documentation.
- Support timely review when a file is shared more broadly.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Basecamp once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis what you want from any channel.
- 3In one instruction, ask Notis to summarize the file and newly granted permissions in a Basecamp Vault document for project review.
- 4Pick the Google Drive File Shared trigger and choose where run reports should go.
- 5Test with one real permission change and review the resulting record.

It detects new sharing permissions granted to a Drive file or folder. The event includes the current permission set so changes can be compared with previously seen permissions.
Does this remove or change anyone's access?
