Authentication failed for FindingService

For the last month I have been getting this error about 50-75% of the time when I call the FindingService Soap call Authentication failed : Missing required credential for authn method I am using http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsAdvanced&SECURITY-APPNAME=xxxxxxx (where xxxxxxx is my app id) for a year or so and haven't changed anything. The fact that it only errors 50-75% of the time points to an error on ebay's side.

Hmm.... Looks like the forum cut off the rest of your call. Can you try again? I've never used SOAP, but I'll fiddle with it via XML.

I don't use SOAP, but I think you need to revise some of your URL parameters: From: X-EBAY-SOA-SERVICE-VERSION To: SERVICE-VERSION From: X-EBAY-SOA-SECURITY-TOKEN To: SECURITY-APPNAME From: X-EBAY-SOA-OPERATION-NAME To: OPERATION-NAME From: X-EBAY-SOA-MESSAGE-PROTOCOL To: ...might need to be sent in the header, rather than in the URL.

The error message has nothing to do with the solution. I've found that adding the following header to the request helped. 'Content-Type' => 'application/xml' Other content type such as 'text/xml' do not work.
