Mobile push notification API

Mobile push notification API

Is it possible to integrate ZOHO CRM with Firebase Cloud Messaging to send push notifications to the custom apps. Or does ZOHO CRM has some library or sdk for it. 

Scenario is i have my app installed and working in client's phone (both Android and iOS), now i want to integrate ZOHO such a way that i can send push notifications to my app through ZOHO CRM platform.
