Here it is : 1) The default response is XML, its not jSON as mentioned in the link. Request Header Host: data.usajobs.gov Within the Request Header, you also need to identify which format you desire. JSON is the default value if not specified: Content-type: application/json Content-type: application/xml 2) As mentioned in the link as "The REST API does not require authentication and is open to all consumers.", I do see an Authorization error while trying to invoke a call via a mobile app which is underdevelopment. 3) When I am directly using the link in browser, I am getting the response in XML format like for this callhttps://data.usajobs.gov/api/jobs?series=2210https://data.usajobs.gov/api/jobs?Title=Manager but when I am invoking this call from MObile ap, its saying Authorization Error. Kindly let me know,how can I proceed with developing my app using this Services & so many errors.
