How to get workflow ID

Hi all,

I am using below code it worked for me:

var req = new XMLHttpRequest();

req.open("GET", Xrm.Page.context.getClientUrl() + "/XRMServices/2011/OrganizationData.svc/WorkflowSet?$select=WorkflowId&$filter=Name eq 'test%20name' and  ParentWorkflowId eq null and StateCode/Value eq 1", true);

req.setRequestHeader("Accept", "application/json");

req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

req.onreadystatechange = function() {

   if (this.readyState === 4) {

       this.onreadystatechange = null;

       if (this.status === 200) {

           var returned = JSON.parse(this.responseText).d;

           var results = returned.results;

           for (var i = 0; i < results.length; i++) {

               var workflowId = results[i].WorkflowId;

           }

       } else {

           Xrm.Utility.alertDialog(this.statusText);

       }

   }

};

req.send();

I am wondering with ODATA. It will obsolete by Microsoft.

I have a work around for that I used below query but it is too complicated:

<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="workflow">
<attribute name="workflowid" />
<attribute name="name" />
<attribute name="category" />
<attribute name="primaryentity" />
<attribute name="statecode" />
<attribute name="createdon" />
<attribute name="ownerid" />
<attribute name="owningbusinessunit" />
<attribute name="type" />
<order attribute="name" descending="false" />
<filter type="and">
<condition attribute="type" operator="eq" value="1" />
<filter type="and">
<condition attribute="rendererobjecttypecode" operator="null" />
<filter type="or">
<condition attribute="category" operator="eq" value="0" />
<filter type="and">
<condition attribute="category" operator="eq" value="1" />
<condition attribute="languagecode" operator="eq-userlanguage" />
</filter>
<condition attribute="category" operator="eq" value="3" />
<condition attribute="category" operator="eq" value="4" />
</filter>
</filter>
<condition attribute="name" operator="eq" value="Clone Service Object" />
</filter>
</entity>
</fetch>

I think this query will impact on performance. Is there any other way to get workflow id?

Thank you
