Hi.
In the documentation it says that it is not possible to create reports for the REST API, but it is possible to return the data processing by the REST API (help.opmanager.com / # rest_api)
REST technology does just return data in JSON format from a URL to that we have in OpManager, the urls extraction informed the link above data.
See for example the link on the method, getBusinessDetailsView, where he follows the pattern http://localhost:8060/api/json/discovery/addBusinessView?apiKey=081c9ac51ba16ab061d5efee583dcd2f&bvName=test
As http://help.opmanager.com/ link # rest_api
field addBusinessView
Regards,
