When you publish a message with mobile push payload attributes (pn_apns and pn_gcm), the specified mobile push messages will always be sent to all devices registered for mobile push notifications on the channel that the message was published to.
{
"pn_apns": {
"aps": {
"alert": "Your order is ready for pickup!",
"payment_info": {
"credit_card": 987656789876,
"expiration": "0108"
}
}
},
"pn_gcm": {
"notification": "Your order is ready for pickup!",
"payment_info": {
"credit_card": 987656789876,
"expiration": "0108"
}
},
"message": {
"info": "This is data all non-APNS and non-GCM devices would receive. They would also receive the pn_apns and pn_gcm data."
"note": "Your order is ready for pickup!",
"payment_info": {
"credit_card": 987656789876,
"expiration": "0108"
}
}
}The entire payload above will be sent to active PubNub subscribers (including the pn_apns and pn_gcm data). But only the data inside the pn_apns section will be sent as an APNS message to registered iOS devices and data inside the pn_gcm section as an FCM message to registered Android devices, and displayed a push notification.
