Adding New Contact Record: 400 Error

[StephenJ85]

Hello! I'm a developer trying to build a simple add contact script in .NET. (I'm talking about a brand-new contact here, not about adding an existing contact to a contact list.)  I'm authenticating fine using basic HTTPS, but I'm getting a 400 error every time I try to send new contact XML. According to the documentation, that means my XML is probably ill-formed, but I built my code based on the sample ASP.NET signup form project on SourceForge (http://sourceforge.net/projects/ctctnetcontact/).  Can someone please take a look and tell me what I'm missing?

Hi Stephen,

I notice in your XML that many of the tags are all lower-case. However, XML is case sensitive. So, for example, you have <optinsource>, but the correct casing is <OptInSource>. Our XML elements are camel cased.

Regards,

Thank you sincerely!  I'm not sure how some of the tags got that way, since I literally copy-pasted right out of the sample project.  But sure enough, the sample project had good capitalization and my code did not.  (I think maybe it was because, to start with, I commented out those particular lines of code... maybe Visual Studio did something crazy, or else I accidently hit some other shortcut while those lines were highlighted).

In any case, I fixed the capitalization and now I'm set.  Thanks for your help!
