APNS Security Update

Apple recently announced an APNS Security Update, requiring updated server certificates for push notifications starting March 29, 2025. If you rely on Apple Push Notification Service (APNS) for delivering notifications to iOS devices, you may be wondering what actions, if any, are needed to ensure uninterrupted service.

We’re excited to confirm that Courier customers are unaffected by this update. Notifications sent via APNS with P8 keys or P12 certificates work seamlessly, and no immediate changes are required.
