I am using urban airship for sending push notification, i finished all configuration in my app and i can send notification from urban airship website.

Now i have to request urban airship api for sending push notification (using this " https://go.urbanairship.com/api/push/") URL and i have send json like this

{
    "apids": [
        "some APID",
        "another APID"
    ],
    "aliases": ["my_alias"],
    "tags": ["tag1", "tag2"],
    "android": {
         "alert": "Hello from Urban Airship!",
         "extra": {"a_key":"a_value"}
    }
}

i want to send push notification for single device, i think i have to do this using APID, isn't it?.
