Log a void in Notion, cancel the Square invoice
A deal falls through or an invoice was wrong, you note it in Notion, but Square keeps chasing the customer for payment. Notis cancels the invoice the moment you log the request, so no one gets billed by accident.
Trigger
New Page
Triggers when a new page is added to a Notion database.
Action
Cancel Invoice
Cancels a Square invoice, preventing further payments from being collected. Requirements: - Invoice must be in SCHEDULED, UNPAID, or PARTIALLY_PAID state - Cannot cancel invoices in DRAFT state or terminal states (PAID, REFUNDED, CANCELED, FAILED) - Requires INVOICES_WRITE and ORDERS_WRITE OAuth scopes - Version number must match the current invoice version to prevent conflicts After cancellation, the associated order status is set to CANCELED and webhook events are triggered.
Why this helps
Invoices that should be voided get flagged in Notion, but the actual Square cancellation lags, so customers keep receiving payment reminders they should not.
- Mistaken invoices are cancelled before the next reminder goes out.
- Customers are not chased for money they do not owe.
- The decision to void is logged once in Notion and acted on in Square.
- Fewer awkward apology emails about a bill that should not exist.
Setup
Build it in a few focused steps.
- 1Connect Notion and Square to Notis once from the portal.
- 2Create the automation in Automations or ask Notis from any channel.
- 3Describe it plainly, like 'When a void request is added in Notion, cancel the matching Square invoice.'
- 4Pick New Page as the trigger and choose the channel for run reports.
- 5Add one test void request and confirm the invoice is cancelled in Square.
Questions about this workflow
Which invoices can be cancelled?
Square allows cancelling invoices that are scheduled, unpaid, or partially paid. Notis reports back if an invoice is in a state that cannot be cancelled.
Can I require approval first?
Yes. Tell Notis to act only on requests marked approved, so nothing is cancelled without sign-off.
How does it find the invoice?
Notis matches the request to its Square invoice using the details you describe, without any manual field configuration.

Supported Triggers and Actions
Notis builds workflows that link Notion to Square. A trigger fires from one place; an action lands in another.
Notion triggers
Square actions
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Accept Dispute
Accept a dispute and acknowledge liability, returning funds to the cardholder. When you accept a dispute, Square debits the disputed amount from your account and updates the dispute state to ACCEPTED. This action is irreversible - once accepted, a dispute cannot be challenged. Only use after reviewing all evidence and determining that challenging the dispute is not viable. Note: Requires DISPUTES_WRITE permission scope.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Add Group to Customer
Tool to add a customer to a customer group. Use when you need to associate a customer with a specific group for targeted marketing, loyalty programs, or customer segmentation.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Calculate Order
Tool to preview order pricing without creating an order. Use when you need to calculate the total cost, taxes, discounts, and other pricing details for an order before finalizing it. Particularly useful for integrating rewards, discounts, and complex pricing scenarios.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Cancel Booking
Cancels an existing Square booking, terminating the reservation. Use this action when a customer or seller needs to cancel a scheduled appointment. The booking must be in a cancellable state, and the cancellation will update the booking status accordingly. This action is irreversible - once a booking is cancelled, it cannot be restored and must be rebooked if needed. Use the booking_version parameter to ensure safe concurrent updates.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Cancel Invoice
Cancels a Square invoice, preventing further payments from being collected. Requirements: - Invoice must be in SCHEDULED, UNPAID, or PARTIALLY_PAID state - Cannot cancel invoices in DRAFT state or terminal states (PAID, REFUNDED, CANCELED, FAILED) - Requires INVOICES_WRITE and ORDERS_WRITE OAuth scopes - Version number must match the current invoice version to prevent conflicts After cancellation, the associated order status is set to CANCELED and webhook events are triggered.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
Cancel Payment
Cancels (voids) a payment that is in APPROVED status. This is typically used in delayed capture scenarios where a payment was authorized but not yet captured, allowing you to void the authorization before settlement. Important: Only payments with APPROVED status can be canceled. Attempting to cancel a payment in any other status (COMPLETED, PENDING, CANCELED, FAILED) will result in an error. Once canceled, the payment status changes to CANCELED and the card details status changes to VOIDED. Required permissions: PAYMENTS_WRITE
New Page
Triggers when a new page is added to a Notion database.
Batch Create Inventory Changes
Applies multiple inventory adjustments and physical counts in a single batch request. Returns the created changes and current inventory counts for all affected items. Use this action when you need to update inventory quantities for multiple items or locations at once, either through physical stock counts or adjustments (e.g., receiving stock, recording waste, or correcting discrepancies). Supports up to 100 inventory changes per request. Each change can be either a PHYSICAL_COUNT (setting absolute quantity) or an ADJUSTMENT (modifying quantity with state transitions). The ignore_unchanged_counts parameter controls whether calculated counts are returned in the response.
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
Create Bulk Customers
Tool to create multiple customer profiles in a single request. Use when you need to efficiently create up to 100 customers at once. Each customer is identified by a unique idempotency key.
