Send a simulated tracking event to your registered webhooks so you can verify that your integration receives and processes tracking status updates correctly.

When to use:
Call this endpoint during development to test your webhook handler before going to production. It sends a realistic tracking-update payload to the webhooks previously registered in your account.

Prerequisites:

Valid JWT authentication token (Bearer)
At least one webhook URL previously registered in your account
A tracking number to include in the test payload
Sandbox environment only — this endpoint is not available in production

Key behaviors:

Sends a test POST request to the registered webhook endpoints
The payload structure matches the format used by real production webhooks
Returns success or failure indicating whether the test notification was triggered
Use this to validate your webhook handler logic, response codes, and error handling before going live
