Why this helps
Files that disappear from shared work can leave teams unsure what changed and when.
- Keep a queryable record of deletion events.
- Review files moved to trash or permanently deleted.
- Make operational follow-up easier.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, then add a name, prompt, report channel, and trigger.
- 3Tell Notis to record available deletion event details in your existing ClickHouse table; provide its database, table, and column names.
- 4Choose the File Deleted or Trashed trigger and where run reports should go.
- 5Test with one real deletion or trash event and inspect the resulting record.

List ClickHouse Tables
List tables in clickhouse databases. returns information about tables including their engine, size, and row count.
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.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
