Integrating with FCM for push notifications

[PXW Google Service]

Hello Everyone! 

I'm currently working on a web-application for e-alerts and notifications. 

I'm analyzing the addition of a new feature, sending push notifications through the web-application. The idea is to integrate the web-app with FCM with mobile apps.

Does FCM charges any fees for push notifications?

[Joe Spiro]

FCM's is a No-Cost offering.

Thank you for your response.

One more question:

What delivery statistics for push notifications can be obtained when sending them through Firebase and how?

[Joe Spiro]

You can look into message send and delivery rates using the aggregate delivery API, Analytics as Displayed in the Console and Google Analytics and through BigQuery Export.
