SOAP call to AccountCombinationService via APEX_WEB_SERVICE.make_request returns null
Summary
Using APEX_WEB_SERVICE.make_request to call fscmService/AccountCombinationService but the response returned is NULLContent
Doing a SOAP call with the payload (listed in bottom) in Postman is working fine.
But when I try to execute same payload from the Oracle database (APEX) via APEX_WEB_SERVICE.make_request it returns NULL.
It should return an XMLTYPE document. I have seen similar issue calling other SOAP services which I solved with fixing the g_request_headers.
But it still does not work for me in this case.
Code snippet;
apex_web_service.g_request_headers.delete;
apex_web_service.g_request_headers(1).name := 'Content-Type';
apex_web_service.g_request_headers(1).name := 'Content-Type';
