According to doc item 1, rule 23597, item 23587, section 23589... this link returns data from sources

https://www.googleapis.com/fitness/v1/users/me/dat...

There is also a distance, calories and steps, but without counters.

I'm trying to get according to their dock item 23576, section 235638463498672349672-9346 and the next hell find the dock steps with

{
  "aggregateBy": [{
    "dataTypeName": "com.google.step_count.delta",
    "dataSourceId": "derived:com.google.step_count.delta:com.google.android.gms:estimated_steps"
  }],
  "bucketByTime": { "durationMillis": 86400000 },
  "startTimeMillis": 1438705622000,
  "endTimeMillis": 1439310422000
}

And I get the above error.

I will say right away, I saw the answer on the stack about the synchronization of accounts. Everything is fine with this, the phone and google fit use one acc, and yes, it already has steps, distance and so on on the counter.
