I am calling the webservice through the .Net wrapper, I am getting a Internal Server Error (500) or a Bad Request (400) while trying to create a Email Campaign. Whom should I contact to see what is wrong with the message.
400 and 500 errors in the Campaigns portion of the wrapper are typically caused by the content you're sending us being either incomplete (missing required fields) or invalid (such as not HTML encoding the TextContent or Content attributes prior to sending the request). To trouble shoot this, we'd need to get the exact XML of the request you're sending over. If you could post that here or send it in an email to firstname.lastname@example.org, we can look at the content and help track down the cause.
