Integrating Salesforce CRM to Exact Target

Question

I Have a requirement to call Soap API of Exact target via a callout from my Salesforce CRM Apex class. I am using the WSDL2APex approach and i'm able to successfully make the call to exact target and receive the response when i pass the security tag with Usernametoken details.

However, due to some implicit requirements, I have a necessity to pass the fueloauth element instead of username and password in the soap envelop.

Below is the sample inner class i have for the header. However, it is adding an additional wrapper <Header> which I am not able to figure out how to remove. Need some help here.

 public class Header{
        public String fueloAuth;
        private String[] fueloAuth_type_info = new String[]{'fueloAuth','http://exacttarget.com','String','1','-','false'};
        private String[] apex_schema_type_info = new String[]{'','true','false'};
        private String[] field_order_type_info = new String[]{'fueloAuth'};       
   }   

code in my stub class is as below to add the header, where i have the webserviceCallout.invoke method.

  public ETPartnerAPI.Header Header;
  private String Header_hns = 'env:Header=www.exacttarget.com'; 

generated output is

<env:Header>
  <env:Header xmlns="www.exacttarget.com">
     <fueloAuth>somevalue</fueloAuth>
  </env:Header>
</env:Header>

What i'm looking at is

  <env:Header xmlns="www.exacttarget.com">
     <fueloAuth>somevalue</fueloAuth>
  </env:Header>

Answer 1

My understanding is a simple string soap header isn't supported.

From apex_callouts_wsdl2apex.htm

WSDLs that don’t use the document literal wrapped style. The following WSDL snippet doesn’t use document literal wrapped style and results in an “Unable to find complexType” error when imported.
