I am writing a native (non-shopify) iOS/Android mobile app for a customer, and they would like push notifications of shopify events in that app. I was wondering, does the backend node.js of a shopify app have the ability to use the firebase admin node.js sdk to push out notifications, and would there be any sandboxing or firewall issues that would block this call from making it to Firebase from the node.js backend of the Shopify app?
@IanDuncanson did you find an answer to your question and did you move forward with Firebase push notifications? We are also writing a native iOS/Android app and we were planning to use Firebase for push. Thanks!
