Adjust payments based on metrics
Your pricing changes as costs fluctuate. Instead of manually updating payment intents, Notis adjusts them based on your metric changes.
Trigger
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
Action
Update Payment Intent
Updates a stripe paymentintent with new values for specified parameters; note that if `currency` is updated, `amount` might also be required, and certain updates (e.g., to `payment method`) can necessitate re-confirmation by the customer.
Why this helps
Prices tied to metrics (usage, market rates, etc.) require constant manual updates across Stripe. For dynamic businesses, this is a cognitive drain.
- Payment amounts update automatically with your metrics
- No manual Stripe adjustments needed
- Prices always reflect current conditions
- Fewer customer disputes over amounts
Setup
Build it in a few focused steps.
- 1Create a Google Sheet with a metric (e.g., Current Pricing = SUM(costs) * 1.2)
- 2Connect Google Sheets and Stripe to Notis
- 3Create the automation: 'When my pricing metric changes, update the pending payment intent amount in Stripe'
- 4Select the trigger: Aggregate Metric Changed
- 5Test by adjusting your costs and confirming the payment intent amount updates
Questions about this workflow
What if a customer has already paid?
Updates apply only to pending intents. Notis won't alter completed payments.
How does Notis know which payment intent to update?
Include a customer ID or reference column and mention it in your prompt.
Can I notify the customer of a price change?
Yes. Ask Notis to send an email: 'Update the payment intent and notify the customer of the new amount'.

Supported Triggers and Actions
Notis builds workflows that link Google Sheets to Stripe. A trigger fires from one place; an action lands in another.
Google Sheets triggers
Stripe actions
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
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.
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
Confirm payment intent
Confirms a stripe paymentintent to finalize a payment; a `return url` is necessary if the payment method requires customer redirection.
Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
Create Customer
Creates a new customer in stripe, required for creating charges or subscriptions; an email is highly recommended for customer communications.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
Developer Metadata Changed
Triggers when developer metadata entries change (new/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
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.
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
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 Rows in Google Sheet
Simple polling trigger that monitors Google Sheets for new rows. Detects when new rows are added and returns the complete row data. Perfect for triggering any workflow based on new sheet entries.
Create product
Creates a new product in stripe, encoding the request as `application/x-www-form-urlencoded` by flattening nested structures.
New Sheet Added in Google Spreadsheet
Polling trigger that detects when a new sheet is added to a Google Spreadsheet.
Create Refund
Creates a full or partial refund in stripe, targeting either a specific charge id or a payment intent id.
