Request Document Approvals Instantly via WhatsApp Buttons
Document updates need quick approvals. Notis sends WhatsApp buttons—Approve, Request Changes, or Needs Discussion—so stakeholders can provide feedback without opening the document.
Trigger
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Action
Send interactive buttons
Send an interactive button message to a whatsapp number. button messages allow users to quickly respond by tapping up to 3 predefined buttons. perfect for yes/no questions, quick choices, or call-to-action scenarios. note: the message will be delivered to the recipient only if they have texted first.
Why this helps
Approval loops get stuck because people don't check email or don't revisit the document. For neurodivergent founders, waiting for feedback drains attention and momentum.
- Get approvals faster without asking people to re-open documents
- Streamline feedback loops with one-tap responses
- Keep document workflows moving quickly
- Reduce email back-and-forth and maintain momentum
Setup
Build it in a few focused steps.
- 1Connect Google Drive and WhatsApp to Notis.
- 2Create a new automation and tell Notis: 'When a Google Docs is updated, send WhatsApp approval buttons to [stakeholder phone/group]: Approve, Request Changes, or Needs Discussion.'
- 3Set the trigger to 'File Updated' and choose WhatsApp as the channel.
- 4Test by updating a Google Doc and verify the WhatsApp approval buttons appear for stakeholders.
- 5Refine the recipients or button options in your prompt if needed.
Questions about this workflow
Can I add custom approval states beyond Approve/Request Changes?
Yes. You can customize approval buttons (e.g., Approve, Minor Changes, Major Revision, Reject) in your automation prompt.
Does the approval request include a link to the updated document?
Yes. The WhatsApp message includes a link to the Google Doc so stakeholders can review if they choose.
Can I automate next steps based on approval decisions?
Yes. When someone taps Approve, Notis can move the document to a final folder, notify other stakeholders, or create follow-up tasks.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Whatsapp. A trigger fires from one place; an action lands in another.
Google Drive triggers
Whatsapp actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Create message template
Create a new message template for the whatsapp business account. templates must be approved by whatsapp before they can be used. templates are required for marketing messages and messages sent outside the 24-hour window.
File Created
Triggers when a new file is created in Google Drive.
Delete message template
Delete a message template from the whatsapp business account. this permanently removes the template and it cannot be recovered. only delete templates that are no longer needed.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Get business profile
Get the business profile information for a whatsapp business phone number. this includes business details like description, address, website, and contact info.
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.
Get media
Get information about uploaded media including a temporary download url. the download url is valid for 5 minutes and can be used to retrieve the actual media file. this is useful for downloading media that was sent to your whatsapp number.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Get media info
Get metadata about uploaded media without generating a download url. this is useful for checking file size, type, and hash without downloading the file. use get media if you need the actual download url.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Get message templates
Get all message templates for the whatsapp business account. templates are required for sending messages outside the 24-hour window and for marketing/utility messages.
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``.
Get phone number
Get details of a specific phone number associated with a whatsapp business account.
Get phone numbers
Get all phone numbers associated with a whatsapp business account (waba).
