I'm trying to update and insert Leads using the Zoho CRM API and I sometimes get the following error:
<response><error><code>4600</code><message>Unable to process your request. Please verify if the name and value is appropriate for the "xmlData" parameter.</message></error></response>
My problem is that sometimes everything works fine and sometimes I get this error, but I'm struggling to see any difference between 'good' XML and 'bad' XML. I'm enclosing all values in CDATA tags.
