Set up Castingwords completion notifications from a Drive comment
Turn a deliberate comment on a shared operations document into a prompt to register the transcription notification endpoint.
Trigger
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Action
Register Webhook
Tool to register a webhook url to receive transcript completion notifications. use when you want castingwords to post transcript-complete events to your service endpoint.
Why this helps
Webhook setup can get buried in account admin work, leaving teams without the completion notifications they expected.
- Use a clear comment as a cue to register a notification endpoint.
- Keep webhook setup connected to a shared operations document.
- Reduce missed setup follow-up.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Castingwords once in the Notis portal.
- 2Create an automation in the portal or tell Notis from any channel what outcome you want.
- 3In one instruction, ask Notis to register the Castingwords webhook URL you provide when a new comment requests notification setup.
- 4Pick the Google Drive Comment Added trigger and choose where run reports should go.
- 5Test with one real comment and review the run report.
Questions about this workflow
Does the Drive comment provide the webhook URL?
Not necessarily. Provide the webhook URL in your instruction or otherwise make it available to Notis; the listed event only describes a new comment.
Does this confirm the webhook is working?
Register Webhook registers the URL. Use the separate Test Webhook Call action to test notifications.
Can I use this to order a transcript?
This workflow registers notifications. Ordering a transcript is a separate action.

Order Transcript
Tool to create a new transcription order for audio/video at a url. use when you have an accessible media url and need to initiate transcription.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Order Upgrades
Tool to order an upgrade for a specific audio file. use after transcription is complete to add items like timestamps or extra editing. example: 'order timestamps for file 12345'.
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.
