Supported Triggers and Actions
Notis builds workflows that link Google Calendar to Square. A trigger fires from one place; an action lands in another.
Google Calendar triggers
Square 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.
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.
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.
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.
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.
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.
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).
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.
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
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.
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).
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
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.
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.
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.
Four ways to start an automation.
A trigger is the event that kicks a workflow off. Notis supports four kinds: an event in a connected app, an inbound webhook, a recurring schedule, and soon, your own database.
Integration triggers
Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,000+ apps can start a workflow.
Webhook triggers
A unique URL per workflow. Anything that can send an HTTP POST can start an automation, including no-code tools that speak webhooks.
Recurring triggers
Cron-style schedules run a workflow on the clock. Daily standups, hourly syncs, business-hours-only digests: the workhorse of Notis.
Database triggers
Watch a row, query, or threshold in your own database and fire the moment the data changes. Row inserted, value crosses a limit, query starts matching.
Classic automation breaks. AI adapts.
Same triggers and actions, smarter middle. AI handles the fuzziness that breaks traditional Zapier-style workflows the moment a field gets renamed.
Describe it. Notis builds it.
Skip the visual builder. Tell Notis what you want, in plain English. It writes the workflow, you review and deploy.
