Toast API Developer's Guide

The webhook service checks for updates when:

The restaurant_availability webhook sends updates when a restaurant's autofire device has stopped auto-approving orders for five minutes. The restaurant availability service runs every minute to check if at least one order has been abandoned, meaning it has not approved and autofired an order within a five minute period. For example, if your guest placed an order at 9:02 AM, and your restaurant stopped auto-approving orders at 9:02 AM, the service runs at 9:03 AM but does not fire a webhook event because only one minute has passed since the order was created and not approved. When the service runs at 9:07 AM and the order was still not been approved, the webhook event fires. For more information about autofiring orders, see Setting up Order Auto-Firing.

Restaurants using Toast Online Ordering with Manual Approval or Approval Rules configured do not trigger webhook events with the AVAILABILITY_OFFLINE reasonKey. Only restaurants that choose to “Send orders directly to the kitchen” are included in the ONLINE and OFFLINE webhook alerts for this scenario. Restaurants can configure their approval options in the Toast administration back-end. These settings do not apply to online ordering integration partners. Orders sent via the orders API are immediately autofired to the kitchen. For more information, see Orders API Limitations.
