The APNs for MDM settings page lets you generate or upload your Apple Push Notification service (APNs) certificate, which is required to manage Apple devices. If you do not already have an APNs certificate, you can generate a new one on this page. If you do have such a certificate, you can upload it here.

For more information, please see the APNs for Applications Renewal Script Notification KB article: https://support.workspaceone.com/articles/360010936073.
