There are a few options for it! Let's take a small ride to understand all the different payloads and their usage.

---

Simple Payload

Displayed in Notification Center : Yes

Wakes app to perform background task : No

{
    "aps" : {
        "alert" : "You received simple notification!",
        "badge" : 1,
        "sound" : "default"
    }
}

Payload With Custom Notification Sound

Displayed in Notification Center : Yes

Wakes app to perform background task : No

Step 1 : Add custom notification sound file (.wav or .aiff extensions only. e.g. notification.wav) in your app bundle.

Step 2 : Configure your payload as shown below to play your custom sound

{
    "aps" : {
        "alert" : "It's a custom notification sound!",
        "badge" : 1,
        "sound" : "notification.wav"
    }
}

Notification With Custom Payload

Displayed in Notification Center : Yes

Wakes app to perform background task : No

{
    "aps" : {
        "alert" : "It's a notification with custom payload!",
        "badge" : 1,
        "content-available" : 0         
    },
    "data" :{
        "title" : "Game Request",
        "body" : "Bob wants to play poker",
        "action-loc-key" : "PLAY"
    },

}

Here the data dictionary holds custom information whatever you want. It will also display as normal notification with the alert message "It's a notification with custom payload!".

Normal Silent Notification

It will not a show an alert as a notification bar; it will only notify your app that there is some new data available, prompting the app to fetch new content.

Displayed in Notification center : No

Awake app to perform background task : Yes

{
    "content-available" : 1
}

---

Silent Notification With Custom Payload

Here comes the magic to show a notification alert as well awake your app in background for a task! (Note: only if it's running in background and has not been killed explicitly by the user.) Just add the extra parameter "content-available" : 1 in your payload.

Displayed in Notification Center : Yes

Wakes app to perform background task : Yes

{
    "aps" : {
        "alert" : "Notification with custom payload!",
        "badge" : 1,
        "content-available" : 1
    },
     "data" :{
        "title" : "Game Request",
        "body" : "Bob wants to play poker",
        "action-loc-key" : "PLAY"
     }
}

Use any of these payloads according to your app requirements. For background app refresh refer to Apple's documentation. I hope this gives you all the necessary information. Happy coding :)

As i understand, you want extra data inside payload, so you can identify what push notification type is,or what action need to be handled.

For that edit your payload as:

 $body = array(
    'content-available' => 1,
    'sound' => ''
    );  

$payload = array();
$payload['aps'] = $body;
$payload['action'] = 'order_update';

Then in your iOS Code:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{


    NSString *action = userInfo["action"];


    if([userInfo[@"aps"][@"content-available"] intValue]== 1 && [action isEqualToString:@"order_update") //order update notification
    {
        //handle Your Action here
        return;
    }


}

Hope this solves your problem!
