I am trying to add a contact and I get the error:
The remote server returned an error: (400) Bad Request.
The account authenticates okay.
This is typically related to the XML structure that you are using to make your request. You can read more about all of our error codes here. If you would like to post the XML that you are using, we'd be glad to take a look and see if we can spot where the error is coming from.
