A push message appears as a notification on a device, informing the user of an action he or she must take. In order to send push notifications to an application, you must have Notification User privilage assigned to your user ID.
When clicked on the notification, the application that is associated with the message is opened. A notification can be sent to a device registered with an application via a REST call to the HTTP Push API.
For SAP Mobile Platform Server available on a network that uses proxy, ensure that the proxy settings are set for the SAP Mobile Platform Server under Settings > System > HTTP Proxy Settings. It allows SAP Mobile Platform Server to access GCM and APNS servers.
If you already have proxy settings set and SAP Mobile Platform Server is not available on a network that uses a proxy, the proxy settings should either be removed or the host for the GCM or APNS server should be added to the non-proxy hosts field.
Both GCM and APNS require open ports that may be blocked on some corporate networks or routers.
Enter the same user name and password later, when you send a notification to the device using the Advanced Rest Client or Postman Rest Client from Chrome Web Store, Google.
You can use any REST tool, such as “Advanced Rest Client” or “Postman”, available from the Google Chrome Web store for testing.
The restnotification API sends native push notifications to the applications. This RESTful service provides more flexibility for sending push messages than existing interfaces that are based on HTTP headers or URL parameters. Earlier push interfaces required that you send messages to a registration ID. The restnotification interface also sends the message to a specific user or to all users of a specific application.
The restnotification API sends messages to multiple recipients. The messages are queued in the server and sent out asynchronously.
