Fault Code 630 Magento API XML-RPC

I'm trying to set up a web store template to sync a Magento web store with Acctivate. when running the sync, magento is returning an error:

ERROR|2014-09-19 10:46:54| |XML-RPC webservice returned error: faultCode = 630 faultString = Unable to read request

The API URL is set to http://ift.tt/1o9696V. I get the same error when I leave out the /index.php

When I manually navigate to the same URL, I get this:

<methodResponse>
<fault>
<value>
