How to get daily step count and active calories from google fitness store via Fitness REST API

Question

I am using nodejs and Google's official "googleapis" module. I am unable to get any value field from any data source.

var count = 0;
               async.eachSeries(dataSources, function (source, nextSource) {
                   count++;
                   console.log(count, source.dataStreamId);
                   console.log('------------------------------------------------------------------------------------------------------------------------------');
                   fitness.users.dataSources.datasets.get({
                       dataSourceId: encodeURI(source.dataStreamId),
                       datasetId: new Date('2016-01-01').getTime() + '-' + new Date().getTime(),
                       userId: "me"
                   }, function (err, data) {
                       if (err) {
                           console.log(err);
                           return nextSource(err);
                       }
                       console.log("Data Set");
                       console.log(data);
                       nextSource(null);
                   });
               }, function nextSource(err) {
                   if (err) {
                       return nextTask(err);
                   }
                   nextTask(null, 'OK')
               });

All I get in response is something like:

{ minStartTimeNs: '1451606400000',
  maxEndTimeNs: '1455532058239',
  dataSourceId:   
  'derived:com.google.step_count.delta:com.google.android.gms:estimated_steps' 
}

Answer 1

I had the same problem, but find the sollution.

"minStartTimeNs: '1451606400000', maxEndTimeNs: '1455532058239'"

They are not in the correct format, the api need epoch time in NANOSECOND (19 number), so its need to 1451606400000000000 and 1455532058239000000
