If you don't know the concept of the connector or don't know how to add this connector to your Sign-in experience, please see [Logto tutorial](https://docs.logto.io/docs/tutorials/get-started/enable-social-sign-in).
> Even if you want to implement Sign in with Apple on a web app only, you still need to have an existing app that embraces the AppStore ecosystem (i.e., have a valid App ID).
You can do it via Xcode -> Project settings -> Signing & Capabilities, or visit [Certificates, Identifiers & Profiles](https://developer.apple.com/account/resources/identifiers/list/bundleId).
See the "Enable an App ID" section in [Apple official docs](https://developer.apple.com/documentation/sign_in_with_apple/configuring_your_environment_for_sign_in_with_apple) for more info.
### Create an identifier
1. Visit [Certificates, Identifiers & Profiles](https://developer.apple.com/account/resources/identifiers/list/serviceId), then click the "+" button next to "Identifier".
2. In the "Register a new identifier" page, choose "Services IDs" and click "Continue".
3. Fill out "Description" and "Identifier" (E.g., `Logto Test` and `io.logto.test`), then click "Continue".
4. Double-check the info and click "Register".
### Enable Sign in with Apple for your identifier
Click the identifier you just created. Check "Sign in with Apple" on the details page and click "Configure".
Enter the domain of your Logto instance without protocol and port, e.g., `your.logto.domain`; then enter the "Return URL" (i.e., Redirect URI), which is the Logto URL with `/callback/apple-universal`, e.g., `https://your.logto.domain/callback/apple-universal`.
> If you want to test locally, you need to edit `/etc/hosts` file to map localhost to a custom domain and set up a local HTTPS environment. [mkcert](https://github.com/FiloSottile/mkcert) can help you for setting up local HTTPS.
## Compose the connector JSON
You need to use the identifier that fills in the [Create an identifier](#create-an-identifier) section to compose the JSON:
```json
{
"clientId": "io.logto.test"
}
```
## Test Apple connector
That's it. The Apple connector should be available in both web and native apps. Don't forget to [Enable connector in sign-in experience](https://docs.logto.io/docs/tutorials/get-started/enable-social-sign-in#enable-connector-in-sign-in-experience).
大功告成。Apple 连接器应该在 web 和原生应用中都可用了。别忘了 [在登录体验中启用本连接器](https://docs.logto.io/zh-cn/docs/tutorials/get-started/enable-social-sign-in/#%E5%9C%A8%E7%99%BB%E5%BD%95%E4%BD%93%E9%AA%8C%E4%B8%AD%E5%90%AF%E7%94%A8%E8%BF%9E%E6%8E%A5%E5%99%A8)。
