For iOS

For the iOS platform, you can authenticate with the authentication token signing key ("APNs key") obtained from the Apple Push Notification system(APNs) issues.

You can get the APNs key from the Apple Developer website and register it as the key itself or a certificate format on the Kakao platform as follows:

Register APNs certificate

To use the APNs certificate as authentication information, you firstly need to register a certificate issued from the Apple Developer website.

1. On your Mac, open the Keychain Access app, and then select [Keychain Access] > [Certificate Assistant] > [Request a Certificate From a Certification Authority...] menu.
2. Enter your Apple ID (Developer account) and your name, select the 'Save to Disk' option, and then click [Continue].
3. On the Apple Developer website, click [Add(+)] in [Ientifiers] > [App IDs] to register a new app. If you have already registered an app, select one or your app IDs to apply push notification.
4. To create a new APNs key, go to [Certificates, Identifiers & Profiles] > [Keys], and click [+] next to the title 'Keys'.
5. Enter the name of an APNs key, select the 'Apple Push Notifications service (APNs)' checkbox to enable the Apple Push Notification service, and then click [Continue].
6. Click [Confirm] and [Download], and then save the APNs key with the .P8 file extension. On the download screen, you can check your Key ID.
7. Drag the downloaded APNs key file to the Keychain Access app to add.
8. On the list of certificates in the Keychain Access app, right-click the APNs key you added and select [Export ${YOUR_APNS_KEY_NAME}].
9. Set the APNs certificate file name, storage location, and password. Notice that you cannot use blank passwords consisting of spaces only for Kakao platform Push notification.
10. In Kakao Developers, click [Register APNs certificate]' in [My Application] > [Push Notification] > [iOS Authentication Information], and then register the following information.

• APNs certificate: Upload the certificate file generated in the Keychain Access app. (Refer to step 8 above.)
• Certificate password: Enter the password specified when generating your certificate. (Refer to step 9 above.)

Register APNs key

To use the issued APNs key as authentication information,

1. On the Apple Developer website, click [Add(+)] in [Ientifiers] > [App IDs] to register a new app. If you have already registered an app, select one or your app IDs to apply push notification.
