As part of the latest release - Release 20.3.1 - Build 9228, one of the new features launched was the iOS Push Notifications improvement.
When integrating your mobile app with Campaign, you need to secure your communication with Apple Push Notification service (APNs). You can use certificate-based or token-based authentication.
These two authentication modes are now available for iOS mobile apps in Campaign Classic:
Token-based authentication (recommended): this authentication mode is based on a .p8 file. This authentication mode is faster as each request to APNs contains the token.Learn more
Certificate-based authentication: this authentication mode is based on a .p12 file. For every app, a separate certificate is required. This certificate is delivered by Apple through your developer account.Learn more
