=== Follow Up === found the correct syntax of the JSON for push notification:

{"data": { "alert": "test message", "sound": "", "badge": "Increment" },"channel":"abc"}

but i found that if the channel is empty, the notification will not work, all i have to do is create channels for the device..... is it true ??

Answer 1

Found the answer finally:

if you have channels, provide the channel name:

{"data": { "alert": "321213", "sound": "", "badge": "Increment" },"channel":"channel name"}

if there is no channels (default no channel), send to all devices:

{"data": { "alert": "321213", "sound": "", "badge": "Increment" },"where": { "deviceType": "ios" }}
