Error receiving push notifications

[descoba]

I am fixing issues with an old Android application written in Kotlin that uses the Sinch service for video calls. However, when FCM was updated, I could no longer receive the notification for an incoming call. Could you help me with the steps to update Firebase data so I can receive these notifications again?

Hi descoba,

Recently FCM was updated to use OAuth2 security. This migration guide should show you everything you need to do to get your service working again: https://developers.sinch.com/docs/in-app-calling/android/migration-to-fcm-v1/

Let me know if you have any further questions.

Thanks,

Hi Alex, thank you very much for your response

I was able to implement my endpoints in the backend according to the guide you shared with me. However, I have a question: do I need to modify something in my Android application compared to how it worked with the previous version of FCM? I’m still not receiving my call notifications

I believe so, yes. This FAQ from google has more information about the deprecated endpoints and what endpoints you should be targeting instead: https://firebase.google.com/support/faq#fcm-23-deprecation
