I am trying to access information about SharePoint 2013 workflows using REST API. Unfortunately, the endpoint for workflow associations that I have found /_api/web/workflowassociations and /_api/web/lists/getbytitle('list')/workflowassociations only returns information about SharePoint 2010 mode workflows, not 2013 mode workflows.
The MSDN documents http://msdn.microsoft.com/en-us/library/windowsazure/jj193504(v=azure.10).aspx talks about a REST API for Workflow Manager, but if you follow the link there is nothing about the actual REST API in the documentation I could find.
I need to be able to get a list of running and completed workflows at the Site and List level. Is there any documentation available on how to use the REST API for the new SharePoint 2013 and Workflow Manager workflows?
