Welcome to the RingCentral Community

Hi, I created an API call using the call log endpoint and using sandbox data. The result shows no records even though there are data in the sandbox (https://service.devtest.ringcentral.com/settings/calls.html#simple). What could be the problem here? Below are the response data: HTTP/1.1 200 OK Server: nginx/1.8.0 Date: Wed, 10 Aug 2016 14:19:44 GMT Content-Type: application/json; charset=UTF-8 Content-Length: 488 Connection: keep-alive Set-Cookie: RCRoutingInfo=B:JjvG963zMhLp2i9ovcWFNFBA3Z0SlO9Db3kZ8SMmxrqqv6l+bmmEQdsVrE5h1Scf; Path=/ RCRequestId: 7c20b8a4-5f05-11e6-91ee-005056bb594d RoutingKey: SJC11P01PAS01 X-LoadMetric: 3 Content-Language: en-US X-Rate-Limit-Group: heavy X-Rate-Limit-Limit: 10 X-Rate-Limit-Remaining: 9 X-Rate-Limit-Window: 60 Vary: Accept-Encoding, User-Agent X-AGW-Host: sjc11-c01-agw02.devtest.ringcentral.com { "uri" : "https://platform.devtest.ringcentral.com/restapi/v1.0/account/131336004/extension/131336004/call-log?view=Simple&dateFrom=2016-08-08T00:00:00.000Z&page=1&perPage=700", "records" : [ ], "paging" : { "page" : 1, "perPage" : 700 }, "navigation" : { "firstPage" : { "uri" : "https://platform.devtest.ringcentral.com/restapi/v1.0/account/131336004/extension/131336004/call-log?view=Simple&dateFrom=2016-08-08T00:00:00.000Z&page=1&perPage=700" } } }
