Push, Live Chat & In-App Messaging FAQs

Frequently Asked Questions on Push, Live Chat and In-App Messaging

Can I get notified when a mobile app user revokes push notification permission?

No, this is not possible because there is no event that is raised by the operating system to notify our SDKs when a user revokes the push notification permission. When you try to send a push notification to a user who has revoked push notification permissions, it will result in an 'UNREGISTERED' error from FCM and APNS. However, this error code can be returned in other scenarios as well such as when a user uninstalls the app. For more information, please refer to this link for more information.
