An authenticated connection to APNs is required to send push notifications to all iOS mobile apps. You only need to use one authentication method, either token-based (.p8) or certificate-based (.p12).

Previous Token Revokation
You can have up to two .p8 keys in your Apple account. If you need to generate a third key, you will need to revoke one of your existing keys and it can no longer be used.
Note: .p8 keys are in the “keys” section of the Apple developer account and the .p12 certificates are under “certificates”. In your Apple account, you can only have two .p8 keys, but you can have both active .p12s and .p8s.
In the OneSignal dashboard, select your app, then go to Settings.
Select Apple iOS.
Add or update authentication, selecting the .p8 Auth Key (Recommended) for APNs Authentication Type.
This is the file you downloaded in Step 2 within your Apple developer account.
This is the unique identifier for the p8 authentication key. You can find your Key ID in the keys section of your Apple developer account. Make sure to use the key for the same p8 key you downloaded in Step 2.
The Team ID is generated by Apple for your developer account. Can be found in the top right of your Apple developer account.
The Bundle ID identifies your app in the Apple ecosystem. You can find your Bundle ID in the Identifiers section of your Apple developer account or within Xcode Main App Target > General > Identity.
