Hi

We are configuring a custom integration from C4C to ERP using SOAP but we are encountering an issue.
The requests from SoapUI are working fine because SoapUI generates following request parameters.

HTTP POST:

Connection: Keep-Alive
Content-Length: 1017
Content-Type: text/xml;charset=UTF-8
Accept-Encoding: gzip,deflate
Authorization: Basic ...
Host: Hostname
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
SOAPAction: "urn:ICustomerService/CreateCustomer"

I think we have to provide a similar construction in C4C in order to generate a successful request.
Currently, we get an empty Response (IsInitial), so it looks like the Request is unable to be processed without above request parameters.
How can we implement this in C4C?

Thanks & regards
