3rd an App will ask you to accept Notifications on either the First install or after the App has been deleted from the device for 24hrs. To get this pop up you have 2 options. A) Delete the App and wait 24hrs before you reinstall. B) Delete the App. Power off the device then turn back on. In Apple push notification there is something called - Feedback Service. So when a user deletes an app, the service provider should ideally stop sending notifications to that device. But Apple does not notify the service that 'this device is not using your app, dont send notifications'. So instead you need to poll for this info. To unsubscribe from push notifications on Safari you can navigate to Preferences - Websites - Notifications. Here you'll get a list of all websites from which you've enabled notifications and you can choose to deny any particular website from sending you further notifications.
Configuring the application
To be able to send APNS notifications to Apple servers or GCM notifications to Google servers, application certificates (APNS) or an application key (GCM) must be specified in the application settings.
Subscribing to notifications
To subscribe to notifications, the client must invoke the account.registerDevice query, passing in token_type and token as parameters that identify the current device. It is useful to repeat this query at least once every 24 hours or when restarting the application. Use account.unregisterDevice to unsubscribe.
The following modes are supported:
![]()
For
10 web push, the token must be a JSON-encoded object with the following keys:
Notification encryption
For FCM and APNS VoIP, an optional encryption key used to encrypt push notifications can be passed to account.registerDevice (
secret ). This key (auth_key ) is used to encrypt the payloads using MTProto v2.

The FCM payload will be a JSON payload, containing a
p field with the base64-encoded encrypted MTProto payload. After decryption, the result will be a JSON object, prefixed by a 32-bit little-endian integer with the length of the JSON payload. As usual, make sure to follow all security checks as described in the MTProto docs.

As mentioned above, payloads can also be encrypted using P-256 Elliptic Curve Diffie-Hellman when using web push.
Notification structure
An (optionally encrypted) notification is provided as a JSON object in the following format:
Each notification has several parameters that describe it.
Notification type
data.loc_key - A string literal in the form
/[A-Z_0-9]+/ , which summarizes the notification. For example, CHAT_MESSAGE_TEXT .
Notification text arguments
data.loc_args - A list or arguments which, when inserted into a template, produce a readable notification.
Custom parameters
data.custom - Parameters which are be passed into the application when a notification is opened.
Sound
data.sound - The name of an audio file to be played.
User id
data.user_id - ID of the account to which the PUSH notification should be delivered, in case of clients with multiple accounts active and running.
Processing notifications
In principle, data.loc_key, data.custom, and an Internet connection are sufficient to generate a notification. Obviously, if possible, when generating a visual notification you need not use all of the transmitted data and may rely on the information already stored on the client. But if a user or a chat is not cached locally, the values passed in loc_args may also be used. data.user_id is the ID of the account to which the PUSH notification should be delivered, in case of clients with multiple accounts active and running.
Service notifications
The following notifications can be used to update app settings.
