In traditional Rally Webservices REST, if I wanted to get all Defects and Stories modified since a certain date, I would need to issue two separate REST GET requests against each of these endpoints:
https://rally1.rallydev.com/slm/webservice/1.33/hierarchicalrequirement
and
https://rally1.rallydev.com/slm/webservice/1.33/defect/
Is there a way to leverage the Lookback API to combine these into one REST request?
Sure, just add _Type:{$in:["Defect","HierarchicalRequirement"]}
to the query. All of the work item types are stored in the same collection. You can also get back descendent Tasks and TestCases.
