Best Method to trigger 'send Push Notifications Application' from SAP

Hi Experts,

We created mobile application and enabled push notifications.

Its working fine, when we sent the push notification for the particular device from the postman plugin, Notifications are going to Mobiles.

Now the question is, How to send the notifications from sap.

we tried following

1. created a BSP application to send notifications, and run it through abap code, It is working fine in front end execution for backend execution it is not working

2.creating a exe file using c# and run it from SAP ABAP code. Here the problem is can't able to pass the values to exe application.

Thanks

Suresh
