Description:
Hi again I was wondering how do you handle diference between APN and FCM/GCM messages on the backend, does your frontend send FCM message to the backend and then some function just convert it to APN or do you use some custom format for that (if you do, what kind of format do you use for that)
Environment
Steps to Reproduce Issue:
question
Anything else:
Thanks for Anwsering and Best Regards
Hi. OneSignal handles communication with the APN Service and FCM separately. Basically, when you send a notification via the OneSignal API or dashboard, we make individual API calls to APNS and FCM, each with its own protocol, to deliver your message.
