To use the stock webhook, you must create a webhook endpoint. This is the URL of a webhook consumer service that can receive webhook events from the Toast platform. Once you have a webhook endpoint, Toast support can create a webhook subscription for your integration that associates your webhook endpoint with stock webhook events.
