How to use premium features in Development?

Hello,

I was messing around with the code in visual studio and was wondering how I can use the premium features on a dummy account.
I don’t want to use my actual account which has them. I was wondering if there was some sort of development feature which allows me to this.

In the web vault, go Go Premium and use a test card number: 4242424242424242

Thanks Kyle,

When I try to do this in the webvault I get the following error:

Is there some sort or test/development mode? Is there any sort of documentation I can refer to?
Also, I was messing with the mobile application if that helps.

You would need to use a development server. Sounds like you are targeting the production server.
