Automatically Cancel Subscriptions When Meetings Get Deleted
When you delete or cancel a calendar event, Notis can automatically cancel the associated Stripe subscription—so you never charge a client for a meeting that never happened. One less thing to remember or regret.
Trigger
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.
Action
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.
Why this helps
You cancel a client meeting or trial onboarding call, and forget to cancel their trial subscription. They get charged. You refund them. It's awkward.
- No accidental charges when you cancel a meeting
- Fewer refund requests and customer support tickets
- Billing stays in sync with your actual calendar
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Stripe to Notis.
- 2Create an automation: 'When I delete a Google Calendar event, cancel the Stripe subscription for that customer at the end of the billing period.'
- 3Set your trigger to 'Event Canceled or Deleted' and confirm the end-of-period timing in your prompt.
- 4Test by canceling a real calendar event and verifying the subscription is marked for cancellation in Stripe.
Questions about this workflow
Will this refund the customer for unused time?
By default, Stripe cancels at the end of the billing period. You can customize this to prorate credits if you want.
What if I delete an event by accident?
You can add a safety step: only cancel subscriptions for events deleted within a specific time window, or require manual approval in your Notis channel.
Does this apply to all deleted events?
No. Filter by calendar or event title—e.g., 'only for events in my Trial Calls calendar' or 'only events with Customer or Paid in the title.'

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.
