An iOS Push Certificate is required for notification delivery to all iOS apps.
- An iOS mobile app. (This is not for websites / web push)
- A Paid Apple Developer Account with Admin Role.
- A OneSignal Account, if you do not already have one.
- A Mac computer with Xcode 11+
- Your Xcode project should have the Push Notification capability added. Otherwise your project may not be shown in the Apple Developer Center.
If your App does not have an existing App ID or Provisioning Profile setup in your Apple Developer Account, then start with below Optional - Provisioning Profiles step.
Generally this occurs when using manual app signing (not have "Automatically manage signing" selected in Xcode) or an app builder like Cordova/Ionic, Gonative, or an older Xcode version.

Previous p12 Push Certificates for this bundle id will be revoked and cannot be used once you generate a new certificate with this method.
