Why there are no parameters in the callback?

Problem/Symptoms

  • Received multiple callbacks without any parameters

Cause

A new or change of webhook URL is provided

Resolution

Every time you input a webhook URL, we will first check the URL with no parameter from multiple servers and expect a 200 OK response. If the URL returns a non 200 OK response, we will not accept it.

You need to make sure the webhook URL returns a 200 OK response even when queried without any parameters.
