I am new to google fit api. I was exploring my own fit account. I find this below data source id in my datasources.

Below is the exact dataSource

 "dataStreamName": "from_sample<-derived:com.google.activity.sample:com.google.android.gms:OnePlus:ONE A2003:10398c01:detailed",
 "type": "derived",
 "dataType": {
  "name": "com.google.activity.segment",
  "field": [
   {
    "name": "activity",
    "format": "integer"
   }
  ]
 },
 "device": {

    dataStreamId is a property that includes a unique identifier- a set of numbers. This is your developer project number, and it will be the same for all requests made using that particular developer account. More of that here.
