  • Log in to the OneSignal dashboard and choose the app you wish to renew the certificate for.
  • In the App Settings, locate the “Apple Push Notification Service (APNS)” section, and hit the “Renew Certificate” button.
  • Follow the instructions to generate a new certificate signing request (CSR) on the Apple Developer Center.
  • Download the renewed certificate to your computer and import it into the Keychain Access app on your Mac.
  • Double-click on the certificate and under the “Trust” section, select “Always Trust” for “When using this certificate”.
  • Exit the Keychain Access app and return to the OneSignal dashboard.
  • Click on the “Upload Certificate” button, select the renewed certificate from your computer and hit “Save” to update the certificate within the app.
  • For compatibility reasons, it’s also smart to regularly update the WebViewGold wrapper portion of your app, although this typically does not need to be done simultaneously with renewing OneSignal certificates.
