Example Usage in Azure
In Azure Logic Apps, creating a webhook trigger involves registering a callback URL with the specified service endpoint. Whenever the specified event occurs, the service sends an HTTP POST request to this URL, triggering the workflow. Similarly, a webhook action can pause a workflow until it receives the expected callback.
