How Testing callback response

If you temporarily need to verify the responses of the 4ws.trade service callbacks, or if for any reason your platform does not support receiving callback responses, here are some guidelines on how to work around these issues.

Please note that handling responses from asynchronous services is mandatory to:

Determine whether the processing was successful.

Identify any errors that may have occurred.

Keep track of the requests that need to be resent.

Using the Existing Service

You can check what you receive when one of the desired events triggers using the services provided by
https://webhook.site/.
Copy the endpoint and use it as the URL for the notification service configuration.
