Automatically Update Subscriptions When Meeting Terms Change
If you reschedule a call or change the scope of work in your calendar, Notis can update the customer's Stripe subscription to match—extend the billing cycle, adjust the plan, or update the service description. One source of truth.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
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
You modify a client's service plan in your calendar notes, but their Stripe subscription doesn't reflect it. Billing doesn't match the actual agreement.
- Billing always reflects the current service agreement
- No mismatches between calendar plans and Stripe billing
- Fewer disputes about what was included in the subscription
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Stripe to Notis.
- 2Create an automation: 'When I update a calendar event, adjust the Stripe subscription to match the new terms.'
- 3Set your trigger to 'Event Updated' and specify which subscription details to sync (plan, price, quantity, etc.).
- 4Test by modifying a real event and verifying the subscription updates in Stripe.
Questions about this workflow
What subscription fields can Notis update?
Plan/price, quantity, billing cycle, description, and custom metadata. Customize in your automation prompt.
Will changes affect the current billing cycle?
You can set whether changes apply immediately or at the next renewal. Specify this in your prompt.
What if the update makes the subscription invalid?
Notis validates changes before applying them. If there's a conflict, it notifies you instead of breaking the subscription.

Supported Triggers and Actions
Notis builds workflows that link Google Calendar to Stripe. A trigger fires from one place; an action lands in another.
Google Calendar triggers
Stripe actions
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
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.
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Confirm payment intent
Confirms a stripe paymentintent to finalize a payment; a `return url` is necessary if the payment method requires customer redirection.
Event Starting Soon
Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.
Create Customer
Creates a new customer in stripe, required for creating charges or subscriptions; an email is highly recommended for customer communications.
Calendar Event Changes
**SOON TO BE DEPRECATED** - Use Calendar Event Sync (polling trigger) instead. Real-time webhook trigger for calendar event changes. Returns event metadata only. For full event data, use Calendar Event Sync (polling trigger).
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.
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
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.
Calendar Event Sync
Polling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook).
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`.
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
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.
