Does FCM work well with AWS SNS?

Question

I am developing a push notifications architecture for our app. I am planning to use AWS-SNS with APNS and GCM. Google now recommends to use FCM (Firebase Cloud Messaging) instead of GCM for new apps. I wanted to understand if FCM is compatible with SNS or there can be some issues ? Are there any workarounds ?

Answer 1

Yes, FCM is backwards compatible with GCM (and thus SNS). I've written a small guide for FCM on SNS in this answer as there are a few gotchas.

The FCM API allows a superset of GCM functionality if you use it directly but functionality wise you don't lose access to anything already available in SNS. It's also nice and easy to use.
