Instant permissions tracking on file shares
Track who has access to what the moment you share a file. Each share automatically creates a dedicated tracking sheet.
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
Add Sheet to Spreadsheet
Adds a new sheet (worksheet) to a spreadsheet. use this tool to create a new tab within an existing google sheet, optionally specifying its title, index, size, and other properties.
Why this helps
You share files with collaborators but quickly lose track of who has access, leading to over-sharing or accidentally restricted files.
- Maintains a clear record of file access for security and accountability
- Reduces the risk of accidental over-sharing
- Makes onboarding and offboarding easier with clear permission trails
- Helps ADHD-prone teams remember who needs what access
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Google Sheets to Notis in your portal.
- 2Tell Notis: 'When I share a file or folder in Drive, create a new Google Sheet named after the file with columns tracking who has access, their permission level, and the share date.'
- 3Select 'File Shared' as your trigger.
- 4Choose your notification channel.
- 5Share a test file and verify that a permissions sheet is created automatically.
Questions about this workflow
Can I track permissions for existing shared files?
This automation tracks new shares going forward. For existing files, you could manually run a one-time import or ask Notis to set up a scheduled sync.
What if I share with a large team at once?
Notis will log all recipients in the tracking sheet, making it easy to see the full group who gained access.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Google Sheets. A trigger fires from one place; an action lands in another.
Google Drive triggers
Google Sheets actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Add Sheet to Spreadsheet
Adds a new sheet (worksheet) to a spreadsheet. use this tool to create a new tab within an existing google sheet, optionally specifying its title, index, size, and other properties.
File Created
Triggers when a new file is created in Google Drive.
Aggregate Column Data
Searches for rows where a specific column matches a value and performs mathematical operations on data from another column.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Append Dimension
Tool to append new rows or columns to a sheet, increasing its size. use when you need to add empty rows or columns to an existing sheet.

Batch get spreadsheet
Retrieves data from specified cell ranges in a google spreadsheet; ensure the spreadsheet has at least one worksheet and any explicitly referenced sheet names in ranges exist.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Batch update spreadsheet
Updates a specified range in a google sheet with given values, or appends them as new rows if `first cell location` is omitted; ensure the target sheet exists and the spreadsheet contains at least one worksheet.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Batch Update Values by Data Filter
Tool to update values in ranges matching data filters. use when you need to update specific data in a google sheet based on criteria rather than fixed cell ranges.
New File Matching Query
Triggers when a new Google Drive file matches a provided query. This is the legacy query-centric trigger: it preserves Drive API query config such as ``corpora`` / ``driveId`` aliases and emits the historical ``file_matching_query`` event type. ``FileCreatedTrigger`` covers the broader "new file" case and emits ``file_created``.
Clear Basic Filter
Tool to clear the basic filter from a sheet. use when you need to remove an existing basic filter from a specific sheet within a google spreadsheet.
Clear spreadsheet values
Clears cell content (preserving formatting and notes) from a specified a1 notation range in a google spreadsheet; the range must correspond to an existing sheet and cells.
