how to adapt old JS CRM 2011 to CRM 2015

Question

I'm new at Microsoft Dynamics CRM and I'm working with CRM 2015. I'm working with CRM 2015 and I've been given to fix an error script developed for CRM 2011. It looks like an old syntax and I don't know how to adapt it to JS for CRM 2015. The script manage the user roles and roles name and I have retrieve the data through fetchXML.

function onChangeValutator()
{  
     var idUser = Xrm.Page.getAttribute("erm_valutatorid").getValue()[0].id;

     // Use the Xrm.Page.context.getAuthenticationHeader() method 
     // available from the CRM form to generate the Soap header text.
     var authenticationHeader = Xrm.Page.context.getAuthenticationHeader();

     // Define the SOAP XML to access Microsoft Dynamics CRM Web service.
     var xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + 
     "<soap:Envelope xmlns:soap="+

Answer 1

Your queries are using the Dynamics CRM 4.0 web service endpoint, which is deprecated. Remove the authentication header from the SOAP message and replace the endpoint address "/mscrmservices/2007/CrmService.asmx" by "xrmservices/2011/organization.svc/web". A nice example can be found here.

With the introduction of the Web API in Dynamics CRM 2016 Microsoft dismissed the SOAP endpoint alltogether, but promised to continue supporting it for the coming years.
