Getting activities list with a distances in Google Fit API (REST) - google-fit

Question

I need to get a list of recent activities in Google Fit, including the distance traveled.
I am using direct REST API requests (PHP via cURL).
First, I do authorization via oAuth 2.0
https://accounts.google.com/o/oauth2/v2/auth?client_id=%CLIENT_ID%&redirect_uri=%REDIRECT_URI%&response_type=code&scope=https://www.googleapis.com/auth/fitness.activity.read%20https://www.googleapis.com/auth/fitness.location.read
After authorization, I'm redirected to my site %REDIRECT_URI%, where the GET request contains "code".
I use this "code" to get the auth token:
POST - https://www.googleapis.com/oauth2/v3/token
POST data: {
'code': %CODE_FROM_GET_PARAM%,
'client_id' => %CLIENT_ID%,
'client_secret' => %CLIENT_SECRET%,
'grant_type' => 'authorization_code',
'redirect_uri' => %REDIRECT_URI%
}
After completing the request, I receive an auth token of the form "ya29.a0ARrdaM-...", I use this token for header Bearer authorization.
I make a request https://www.googleapis.com/fitness/v1/users/me/sessions to get a list of activities:
"session": [
{
"id": "Run1629350880000",
"name": "Run",
"description": "",
"startTimeMillis": "1629350880000",
"endTimeMillis": "1629352020000",
"modifiedTimeMillis": "1629358291250",
"application": {
"packageName": "com.xiaomi.hm.health"
},
"activityType": 8
}, ...
]
Based on this list, I can see the running time (startTimeMillis, endTimeMillis), but I still need to get the distance.
What should I do next?

All actions taken from the question are correct.
Next, you need to send a request to https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate
CURL request:
You can remove "<---" comments and push this CURL code to Postman to see this request with UI
curl --location --request POST 'https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate' \
--header 'Authorization: Bearer %AUTH_TOKEN%' \ <--- Real Auth token
--header 'Content-Type: application/json' \
--data-raw '{
"aggregateBy": [
{
"dataTypeName": "com.google.distance.delta",
"dataSourceId": "derived:com.google.distance.delta:com.google.android.gms:merge_distance_delta"
}
],
"startTimeMillis": 1629350880000, <--- "startTimeMillis" from session data
"endTimeMillis": 1629352020000 <--- "endTimeMillis" from session data
}'
Response:

"endTimeMillis": "1629352020000",
"dataset": [

"originDataSourceId": "raw:com.google.distance.delta:com.xiaomi.hm.health:GoogleFitSyncHelper- distance0",
"value": [
{
"fpVal": 874, <--- distance in meters
"mapVal": []
}
]
}
]
}
]
}
