APN Certificate Guide
Setup APN Certificates for Push Notifications
In the background, OpenBack uses silent Push Notifications to silently update messages and ensure triggers are checked regularly. As such, OpenBack requires a certificate to send those push notification packets.
In the project, a certificate must be created in your Apple Developer Account and uploaded into the OpenBack Dashboard under App Settings. If Push Notifications are used already, OpenBack recommends creating a specific certificate for the OpenBack SDK. iOS applications can have multiple APNs certificates and this additional OpenBack certificate does not interfere with any existing certificates or services in any way.
Please note that p12 certificates expire, and a new certificate needs to be created in your Apple Developer Account and uploaded into the OpenBack Dashboard again.
Go to your apple developer account
