Sending a notification to all devices

Request

To send a notification to all the devices, send a POST request to:

Headers

• Content-Type: application/json

Mandatory fields

• topic_name (in URL) – this is the default topic, GlobalTopicForAllDevices, to which all devices are subscribed automatically.

• envelope object containing at least:

  • from – who the notification is from

• message – the message – base64-encoded opaque data or UTF-8-encoded data with no CR/LFs
  Note that this is client-specific. For ION clients, the message must be in this format (but with CR/LFs removed):

  {
      "data" :
          "{
              "title":"Titles promotions message",
              "message":"Content promotions messages"
          }"
          "notification" :
          "{
                "title":"Titles promotions message",
                "message":"Content promotions messages"
          }"
  }
  

  
  

  The contents of data and notification must be the same.
