I am creating NINTEX workflow 2010 with Custom ASP.NET page in SharePoint 2010 Environment.
When user fills the form, and submits the data, the Nintex workflow starts because I have set the workflow starts when Item created in SharePoint list.
when the workflow is active in the approver step, we have multiple option created for the approver to approve, reject or to return the request back to requester.
My Challenge is on how to update the Nintex workflow task status changes from the code behind when Approver update the status from the form.
You can do it with the Nintex Workflow web services >>> http://myservername/MyNintexSite/_vti_bin/nintexworkflow/workflow.asmx , you can use the method ProcessFlexiTaskResponse2
