# Deregister a Mobile Device for Push Notifications 

You can deregister a device that was registered for Catalyst iOS push notifications by passing the required parameters to the `deregisterNotification()` method as shown below.

```javascript
ZCatalystApp.shared.deregisterNotification(token: e5********21, appID: 1234567, testDevice: true) { error in
            if let error = error
            {
                return print("Error : \( error )")
            }
            print("UnRegistered successfully")
 }

```

**Parameters:**
    
* `token`: `token`: Device token obtained after [registering the device for remote push notifications with APNS](https://docs.catalyst.zoho.com/en/cloud-scale/help/push-notifications/ios/#configure-and-enroll-for-ios-push-notifications).

* `appID`: The `notificationAppID` obtained from the `AppConfigurationDevelopment.plist`/ `AppConfigurationProduction.plist` file generated by Catalyst for your app when you [registered your iOS app in Catalyst](https://docs.catalyst.zoho.com/en/sdk/ios/v2/setup/).
