Please provide any additional information below.
sending above request basically sent request body
POST https://www.googleapis.com/mapsengine/v1/tables/upload?key={YOUR_API_KEY}

{
 "projectId": "1062007310235",
 "name": "Cascadian Train Stations",
 "description": "A partial list of mag-lev stations in the nation of Cascadia.",
 "tags": [
  "stations",
  "train",
  "cascadia"
 ],
 "schema": {
  "columns": [
   {
    "name": "geometry",
    "type": "points"
   },
   {
    "name": "station_name",
    "type": "string"
   }
  ]
 }
}

so key={YOUR_API_KEY}, api_key is not replaced automatically and also not able 
to set api_key in request body.
