有多少用户启用了推送通知？

Question

I have a SAAS product with many users. iOS + Android app.

1) Is there a way to check how many of them have push notifications enabled?

2) Can I programmatically check if they have push enabled? And if not, then I want to trigger alternative communication.

Questions apply for both iOS and Android.

Thank you.

Answer 1

For ios

You'll have to implement a smart solution for do this job.

The initial point is identify a permission users.

As this response : https://stackoverflow.com/a/44407514/6273003

after, you can storage this information with some user identification.

and then, when you decide notificate, you must check this information.

PS : This permission is dynamic as @paulw11 said.

Answer 2

Sorry my answer only about iOS part
I think you need know what users get notification messages and if user don't get message, send it message with alternative chanel.
It can be do (in iOS) with Notification Extension
Just add send delivery status with api request (in your service)

override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
let content = request.content
// send delivery status in your service
sendStatistic(content: request.content, onCompletion: {
    // show push with default content
    contentHandler(content)
})

}
