Problem connecting to SOAP API using Trustpilot

Question

I am trying to connect trustpilot product reviews to Magento for a customer.

When I open the pages where the SOAP API is connecting everything seems alright and I get the XML pages.

The error stems from the response containing an invalid body whenever an error occurs in their API. When we try to determine if we can login to Magento we first try login in with WSI mode, and if we get an error we fall back to V2 mode. We should login with V2 mode, but the error we get by trying WSI mode looks like this:

It contains three XML documents in the body as you can see. The Content-Type is "text/xml; charset=utf-8", which makes the body invalid.

What could be the issue that there are 3 responses instead of just one? I´m using Magento Enterprise 1.7 Thanks

Answer 1

After talking to Magento Support I came to the conclusion that Magento Enterprise 1.7.1 is not supporting WS-I Compliance which is needed for this.
