4. To enable pre-configured permissions depending on the kind of app you are creating, select one of the following options: 
   Native Mobile: Payments using our native mobile. 
   Web Payments: Using our hosted re-direct Web Payments solution. 
   Your Back Office: Using our Server SDKs, or build directly to our API.
5. Click Add app
6. Your new app will appear at the bottom of the list of apps. 
   You can select the app to view and edit the configuration settings.

Note: Each app has a unique configuration, meaning permissions or feature configurations (such as one-click payments) are not shared between all your apps. 
You have to configure each app separately.
