Getting location data from Google Fit Api

Question

I am trying to fetch location data from Google fit activity which I have added through mobile. I am currently using OAuth2 Playground to test the request.

The request URI i am using is : https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate

Request Body

{
  "aggregateBy": [{
    "dataTypeName": "com.google.location.sample"
  }, {
    "dataTypeName": "com.google.distance.delta"
  }],

bucketBySession:{
minDurationMillis: 1
}, 
  "startTimeMillis": 1522281600000,
  "endTimeMillis": 1522368000000
}

Response

              "dataTypeName": "com.google.distance.delta"
            }
          ]
        }
      ]
    }
  ]
}

But these response does not provide a from and to location information which I can show in my website.

1. Is there any other dataTypeName which I can use to get the location information?

2. What is the bounding box data shown? Is it useful in any way to show location?

3. What is the data provided by "dataTypeName": "com.google.distance.delta" mean? Is it the distance between start and end location?

Answer 1

"Location data can only be read by the app that wrote the data. Your app can only read back data it wrote. It cannot read location sample data written by other apps." from developers.google.com
