AWS SNS - How to publish Platform specific payload

 Below is a screen from AWS SNS which helps to do that 

Sample messges formats are

{ "GCM":"{ \"notification\": { \"body\": \"Sample message for Android endpoints\", \"title\":\"TitleTest\" } }" }

{ "GCM":"{ \"notification\": { \"body\": \"Sample message for Android endpoints\", \"title\":\"TitleTest\" }, \"data\": {\"time_to_live\": 3600,\"collapse_key\":\"deals\"}" } }

{ "default": "This is the default message which must be present when publishing a message to a topic. The default message will only be used if a message is not present for one of the notification platforms.", "APNS": "{\"aps\":{\"alert\": \"Check out these awesome deals!\",\"url\":\"www.amazon.com\"} }", "GCM": "{\"data\":{\"message\":\"Check out these awesome deals!\",\"url\":\"www.amazon.com\"}}", "ADM": "{\"data\":{\"message\":\"Check out these awesome deals!\",\"url\":\"www.amazon.com\"}}" }
