I am an android developer, Now I am integrating push notification on my android application. Now I am having a problem,
When I send message from firebase I am getting the push message. But when message sending from backend There is some error. On backend they are getting
"{"multicast_id":4781872077855061201,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}"
Is this is backend issue? ON backend they are using the correct Server key and Sender ID On this C# FCM for Android Push Notification They are telling like,
I found the error. As a back-end developer I worked on C# part only. There is one more step to be done from mobile application side. Mobile app should allow receiving messages from list of Sender Ids so the one that I use in my C# code must be allowed from mobile app side. Once I did that it worked
