Add deep link when creating Firebase message

Question

I'm using the firebase Message class to create push notifications for a react native app. I want the notification to take users to a specific screen of the app. Right now tapping on the push notification just takes users to the last screen they were on before they back-grounded the app. I'm testing this on my iOS device. How can I embed a specific deep link in the message? Would I use setApnsConfig(ApnsConfig apnsConfig) or setFcmOptions(FcmOptions fcmOptions)?

Answer 1

I would use the APNS config since this is for an iOS app:

You could approach it different ways, but you could either include a URL in the header field, and use it for custom deep link logic, or you can have custom data in the putCustomData(String key, Object value) and then have your app process that info to deep link into the correct part of your app.

Your app would process this notification in the application(_:didReceiveRemoteNotification:fetchCompletionHandler:)
