Auto-Update Subscription When Scope Changes
Note a scope change in a comment and Notis updates the subscription in Stripe. Always billing for the right scope.
Trigger
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Action
Update Subscription
Updates an existing, non-canceled stripe subscription by its id, ensuring all referenced entity ids (e.g., prices, coupons) are valid and automatic tax liability is correctly specified if enabled.
Why this helps
A client asks for more services. You note the change in a comment but forget to update their subscription terms in Stripe, so they're being billed for the old scope.
- Adjust subscription terms instantly when scope changes, not days later
- Eliminate overbilling or underbilling from outdated subscription terms
- Keep billing accurate without manual Stripe updates
- Reduce customer disputes about charges
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Stripe integrations.
- 2Create an automation: 'When I add a comment noting a scope or service change, update the subscription in Stripe with new terms.'
- 3Specify the new price, duration, or features in your comment (e.g., 'Upgrade to Premium: $300/month, add analytics').
- 4Select the trigger 'Comment Added' and set your alert channel.
- 5Test by adding a scope change comment and verifying the subscription updates in Stripe.
Questions about this workflow
How does Notis know which subscription to update?
Notis reads the customer name or subscription ID from your comment and the document context, then updates the right subscription in Stripe.
Can it prorate charges for mid-cycle changes?
Yes. Notis can handle prorated charges based on the change date and billing cycle. You can specify 'prorate' in your comment if you want it applied.
What if the new price requires a new Stripe plan?
Notis can create a new price or plan if needed, or you can specify an existing plan ID in your comment.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Stripe. A trigger fires from one place; an action lands in another.
Google Drive triggers
Stripe actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Cancel subscription
Cancels a customer's active stripe subscription at the end of the current billing period, with options to invoice immediately for metered usage and prorate charges for unused time.
File Created
Triggers when a new file is created in Google Drive.
Confirm payment intent
Confirms a stripe paymentintent to finalize a payment; a `return url` is necessary if the payment method requires customer redirection.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Create Customer
Creates a new customer in stripe, required for creating charges or subscriptions; an email is highly recommended for customer communications.
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.
Create an invoice
Creates a new draft stripe invoice for a customer; use to revise an existing invoice, bill for a specific subscription (which must belong to the customer), or apply detailed customizations.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Create payment intent
Creates a stripe paymentintent to initiate and process a customer's payment; using `application fee amount` for a connected account requires the `stripe-account` header.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Create a price
Creates a new stripe price for a product, defining its charges (one-time or recurring) and billing scheme; requires either an existing `product` id or `product data`.
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``.
Create product
Creates a new product in stripe, encoding the request as `application/x-www-form-urlencoded` by flattening nested structures.
Create Refund
Creates a full or partial refund in stripe, targeting either a specific charge id or a payment intent id.
