PHP Google Play订购API

I am trying to get Google Play API subscription details using PHP and using following url to get purchase data :

https://www.googleapis.com/androidpublisher/v1/applications/[PACKAGE]/subscriptions/[SKU]/purchases/[PURCHASE_TOKEN]?access_token=[ACCESS_TOKEN]

I am getting the following error:

{
 "error": {
  "errors": [
   {
    "domain": "androidpublisher",
    "reason": "developerDoesNotOwnApplication",
    "message": "This developer account does not own the application."
   }
  ],
  "code": 401,
  "message": "This developer account does not own the application."
 }
}

Please help me sort out.

Just providing the URL does not help you get data of any application. How can you think so.? Isnt it insecure.? You have to get proper data by which you can at least prove ownership for the app..
