Exception .NET creating properties



Good evening everyone,

I’m trying to create from a .NET application some properties in contact, but I’ve had some troubles when one of them is already created. I want to know how can I detect which is this property from the code (which kind of exception or similar), because the web response only retrieve a 400 error with no more info that bad request.

Thank you in advance.


@cmira can you post the 400 error? There should be some info in the body of the error.
