Mail documents requested in Drive comments
A clear request in a document comment can start the mailing workflow, so the request does not get lost in discussion.
Trigger

Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Action
Send Letter
Tool to send a letter via u.s. mail with specified recipient, sender, and pdf. use after confirming recipient and document details. example: send letter(to name='john doe', to address='123 main st, ...', file url='https://...')
Why this helps
Mailing requests left in document comments are easy to miss among edits and review notes.
- Bring postal requests in Docs, Sheets, or Slides into a defined workflow.
- Use a comment as a prompt to review the request and document.
- Require confirmation of recipient and PDF before mailing.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Docupost once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for comment-based mail requests.
- 3In one instruction, tell Notis how to recognize an explicit postal request in a new comment and to confirm the recipient, sender, and PDF before sending.
- 4Pick Comment Added as the trigger and choose where run reports should go.
- 5Test with one real comment request and verify all mailing details before sending.
Questions about this workflow
Does every comment result in a letter?
No. Explain in your instruction what counts as an explicit mailing request, and require confirmation of the recipient, sender, and PDF.
Can the comment contain all the mailing details?
It may, but the workflow should confirm the necessary recipient, sender, and document details before sending.

Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
File Created
Triggers when a new file is created in Google Drive.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
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.
