Get specific value out of Google Fit API in REST - rest

Question

I am calling the google fit API for the activity between two dates but how do I just get the Activity integers? Is there a direct way to call it from the HTTP request or do I have to filter the JSON data myself?
social_token = SocialToken.objects.get(account__user=2)
token=social_token.token
url = "https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate"
headers = {
"Authorization": "Bearer {}".format(token),
"Content-Type": "application/json"
}
body = {
"aggregateBy": [{
"dataTypeName": "com.google.activity.segment",
}],
"startTimeMillis": 1634767200000,
"endTimeMillis": 1634853600000
}
respo = requests.post(url, data=json.dumps(body), headers=headers)
The JSON response
[
"{\n \"bucket\":
[\n {\n \"startTimeMillis\": \"1634767200000\",\n \"endTimeMillis\": \"1634853600000\",\n \"dataset\":

To get all individual entries for a datatype between a range, you need to use the Users.dataSources.datasets: get API.
The request method will be GET and the endpoint will be
https://www.googleapis.com/fitness/v1/users/me/dataSources/{dataSourceId}/datasets/{datasetId}
where datasetId is of the format StartTimeInNanoseconds-EndTimeInNanoseconds and dataSourceId will be the ID of the dataource against which you want the individual entries. For example, for body temperature, it will be derived:com.google.body.temperature:com.google.android.gms:merged.
To get the list of all the available data source IDs your application has access to, call the API
GET https://www.googleapis.com/fitness/v1/users/me/dataSources
Sample request to get body temperature
GET https://www.googleapis.com/fitness/v1/users/me/dataSources/derived:com.google.body.temperature:com.google.android.gms:merged/datasets/1655750425675000000-1655991535675000000
