Sandbox mode card is always declined using Advanced Integration v2 .net / html example #185
Description
I have compiled the .net / html example of the advanced integration v2 and running the client and server locally on my PC with a valid sandbox client id and secret, but my test card is being declined. I have not made any changes to the code. Is this setup no longer working? The processor response code is always "PPAR".
If you setup the .net example and make a purchase in sandbox mode with a sandbox card does it return status: "DECLINED" for you as well?
Here is the response object in my event log:
