class WebshopappApiException is empty

[Trikitto]

Hi,

First of all, great package!

I wanted to handle a WebshopappApiException but i found out that this class within WebshopappApiException.php is empty. I could edit this class but i would probably lose my changes if at some point a new version of this package is been released.

So i thought about making a custom WebshopappApiException and place it in app/Exceptions but i don't know how to configure that when there is an WebshopappApiException in your package it calls my custom class.

Any help would be greatly appriciated!
