Delivery Channels are specified per-message. To configure a message for APNS, the sending mode must be “SMS Only” and the Delivery Channel should be the APNS Delivery Channel configured above.
In the message content screen, specify a content URL that produces a JSON payload that can be consumed by APNS. Static content or scripted static content URLs may use Connect merge tags.
An example JSON payload is shown below:
{ "aps" : { "alert" : {"loc-key":"%@ has risen to %@",
"loc-args":["HBC","99"]},
"badge" : 42} }
