Webservice encryption

I created an ABAP Webservice using SPROXY for which I needed to add a custom SOAP Header. All this appears to working as I want to, so no issues there.

The issue is that when I call the webservice itself it apparently encrypts the request, how or where I don't know. The problem is that on the receiving end they don't want it encrypted.

Can anybody direct me in the right direction on how I can prevent the webservice encrypting the request?

Thanks in advance
