Solution 1:

Not an appropriate solution but made an end-point in my existing Node project. Any one having this issue can use this. URL https://pankaj-oil-api.herokuapp.com/notify

You need to post this object on above url. "registration_ids" is a string array that can have minimum 1 and maximum 1000 tokens.

{"registration_ids":["Client Token 1","Client Token 2"],"serverKey":"<Your (Authorization) Server Key Here>","title":"<Enter your Notification Title here >","msg":"<Enter your Notification Message here >"}

Code

This is just a temporary solution . Still looking for a solution.
