1. Login to your Jamf Now account at login.jamfcloud.com
2. Select VPP in the navigation bar on the left.
3. Select Users under the VPP section in the navigation bar.
4. To send and invite, click on the [...] button to the right of the device. The option to send a VPP invite will appear in the menu. Click on Send Invite to Device.
When the device is enrolled or receives its first app, Jamf Now will send an invite request to the device to accept apps from your VPP account. The Apple ID that is logged into the device will be the Apple ID that is registered as a user in your VPP account. Once the user accepts the VPP invite, apps will download to the device.
If a device is running iOS 9 or OS X 10.11 El Capitan, no VPP invitation or Apple ID is required to deploy apps. Important: Not all apps can be deployed to a device without an Apple ID. You can find this information in the apps description page.
