I had the same problem and in my case the culprit was the '<Auto Number>' element within the Invoice XML. This is quoted exactly like this in the Saasu API, however is obviously not valid XML and Saasu quite rightly refuses it. I simply removed the tag, i.e. am not creating an invoice number. An alternative would be to define that number manually.
If anyone knows how to send the 'Auto Number' parameter correctly in XML, let me know. -- View this message in context: http://zend-framework-community.634137.n4.nabble.com/Zend-Rest-Client-posted-XML-tp1592951p2714265.html Sent from the Zend Framework mailing list archive at Nabble.com.
