*Update:* - This was my fault. I misread a comment in the sample code and had placed an email address in the webOrder's PhoneNumber property. I assigned a phone number instead and it is now working.
I am trying to implement the .NET integration using the .NET 4.0 library.
My transaction appears to be setup correctly, but the iframe shows the following error:
Problem: parameter_rejected | Advice: unknown_error_occured> oauth_parameters_rejected | String%20or%20binary%20data%20would%20be%20truncated.%0D%0AThe%20statement%20has%20been%20terminated.
I can't determine what is causing the error. None of the values are particularly long. The iframe source link is about 1,357 characters long.
