Send a test event notification. After you create a subscription, you can send a test event notification to your specified URL.
Note: All the fields in the test event notification are test values. You cannot use any of the test values for any other operation.
See Webhooks in the Guides section for more information, sample requests, and notification payloads for BILL events.
