Using RESTful Web Service URL
You can use the REST web service link to manage data in webMethods OneData objects. You can access the data either as an anonymous user or as a webMethods OneData user. When REST fetches the data from an object, it checks for the user privileges and displays the data accordingly. webMethods OneData returns the records in XML/JSON format. For conceptual objects, webMethods OneData returns the child records too.
You can also filter the data returned by REST by providing appropriate filter conditions in the request URL.
