You can use the simulator to post a mock webhook event message to any listener on HTTPS port 443. Alternatively, the Webhooks Management API can be used to trigger simulated events.
Go to the Webhooks simulator. Click Log In.
Enter your webhook listener URL, and select a sample event from the drop-down list.
Click Send Test. The simulator queues and attempts to send the event to your webhook listener URL.
Once the simulator queues the event message, it will reach your webhook listener URL shortly, often within a minute.
Note: These simulated events are for demonstration purposes, to validate the functionality of a webhook listener. You can self-verify the signature of simulated webhooks using the webhook ID string: WEBHOOK_ID. Because they are mock events:
The simulator will show the status and details of the mock message that was sent:
Your event has been successfully queued at May 15, 2024, 9:42:52
If sent successfully, below will be the body event payload of a mock message that was sent. Example:

}If the simulator fails to connect to the listener and deliver the message, the event status is updated with error details. See Troubleshooting delivery problems in the integration guide for information on why deliveries might be failing.
