## Get started

Alipay Native connector works closely with Logto SDK on mobile platforms. It takes advantage of Alipay's OAuth 2.0 authentication workflow and enables Alipay users to sign in to other Apps using public Alipay user profiles without going through a troublesome register process.

## Register Alipay developer account

[Register an Alipay developer account](https://certifyweb.alipay.com/certify/reg/guide#/) if you don't have one.

## Create and configure Alipay app

1. Sign in to the [Alipay console](https://open.alipay.com/) with the account you have just registered.
2. Go to "Web & Mobile Apps" (网页&移动应用) tab in "My Application" (我的应用) panel.
3. Click "Create an App" (立即创建) button to start configuring your application.
4. Name your application in "Application Name" (应用名称) following the naming conventions and upload your "Application Icon" (应用图标), make sure you choose "mobile application" (移动应用) as "App type" (应用类型). For building iOS App, a unique "Bundle ID" is required. Also, "application signature" (应用签名) and "application package name" (应用包名) are required for Android apps.
5. After finishing creating the application, we come to the Overview page, where we should click "add ability" (添加能力) to add "Third-party application authorization" (第三方应用授权), "Get member information" (获取会员信息) and "App Alipay login" (App 支付宝登录) before enabling Alipay sign-in.
6. Go to [Alipay Customer Center](https://b.alipay.com/index2.htm), and sign in with the Alipay developer account. Click "Account Center" (账号中心) on the topbar and go to "APPID binding" (APPID 绑定), whose entrance can be found at the bottom of the sidebar. "Add binding" (添加绑定) by type in the APPID of the mobile application you just created in step 4.
7. Click on "Sign" button of "App Alipay login", and finish signing process following the guide. After finishing this step, you are expected to find abilities you have just added in step 5 kicks in.
8. Come back to Alipay open platform console page, and you can find "Interface signing method" (接口加签方式（密钥/证书）) in "development information" (开发信息) section. Click "set up" (设置) button, and you can find yourself on a page setting signing method. "Public Key" (公钥) is the preferred signing mode, and fill in contents from the public key file you have generated in the text input box.
9. Set up "Authorization Redirect URI" (授权回调地址) by clicking "set up" (设置) button on the bottom of the Alipay console page. `${your_logto_origin}/callback/${connector_id}` is the default redirect URI used in Logto core. The `connector_id` can be found on the top bar of the Logto Admin Console connector details page.
10. After finishing all these steps, go back to the top right corner of Alipay console page, and click "Submit for review" (提交审核). Once the review is approved, you are good to go with a smooth Alipay sign-in flow.

> ℹ️ **Note**
> 
> You can use _openssl_ to generate key pairs on your local machine by executing following code snippet in terminal.
> 
> ```bash
> openssl genrsa -out private.pem 2048
> openssl rsa -in private.pem -outform PEM -pubout -out public.pem
> ```
> 
> When filling in the public key on the Alipay app setup website, you need to remove the header and footer of `public.pem`, delete all newline characters, and paste the rest of the contents into the text input box for "public key".

## Set up the Logto Alipay Native connector settings

1. In [the Alipay console workspace](https://open.alipay.com/dev/workspace) go to "My application" (我的应用) panel and click "Web & Mobile Apps" (网页&移动应用) tab, you can find APPID of all applications.
2. In step 7 of the previous part, you have already generated a key pair including a private key and a public key.
3. Fill out the Logto connector settings:
    - Fill out the `appId` field with APPID you've got from step 1.
    - Fill out the `privateKey` field with contents from the private key file mentioned in step 2. Please MAKE SURE to use '\n' to replace all newline characters. You don't need to remove header and footer in private key file.
    - Fill out the `signType` filed with 'RSA2' due to the `Public key` signing mode we chose in step 7 of "Create And Configure Alipay Apps".

### Config types

| Name       | Type        | Enum values     |
|------------|-------------|-----------------|
| appId      | string      | N/A             |
| privateKey | string      | N/A             |
| signType   | enum string | 'RSA' \| 'RSA2' |

## Enable Alipay native sign-in in your app

### iOS

We assume you have integrated [Logto iOS SDK](https://docs.logto.io/docs/recipes/integrate-logto/ios) in your app. In this case, things are pretty simple, and you don't even need to read the Alipay SDK doc:

**1. Add `LogtoSocialPluginAlipay` to your Xcode project**

Add the framework:

![Add framework](/packages/connectors/connector-alipay-native/docs/add-framework.png)

> ℹ️ **Note**
> 
> The plugin includes Alipay "minimalist SDK" (极简版 SDK). You can directly use `import AFServiceSDK` once imported the plugin.

**2. Add the plugin to your `LogtoClient` init options**

```swift
let logtoClient = LogtoClient(
  useConfig: config,
  socialPlugins: [LogtoSocialPluginAlipay(callbackScheme: "your-scheme")]
)
```

Where `callbackScheme` is one of the [custom URL Schemes](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app) that can navigate to your app.

### Android

We assume you have integrated [Logto Android SDK](https://docs.logto.io/docs/recipes/integrate-logto/android) in your app. In this case, things are pretty simple, and you don't even need to read the Alipay SDK doc:

**1. Download the Alipay "minimalist SDK" and add it to your project**

Download the Alipay "minimalist SDK" (极简版 SDK) from [Logto 3rd-party Social SDKs](https://github.com/logto-io/social-sdks/blob/master/alipay/android/alipaySdk-15.7.9-20200727142846.aar) to your project's `app/libs` folder:

```bash
project-path/app/libs/alipaySdk-15.7.9-20200727142846.aar
```

**2. Add the Alipay "minimalist SDK" as a dependency**

Open your `build.gradle` file:

```bash
project-path/app/build.gradle
```

Add the dependency:

```kotlin
dependencies {
  // ...
  implementation(files("./libs/alipaySdk-15.7.9-20200727142846.aar"))  // kotlin-script
  // or
  implementation files('./libs/alipaySdk-15.7.9-20200727142846.aar')  // groovy-script
}
```

### Test Alipay native connector

That's it. Don't forget to [Enable connector in sign-in experience](https://docs.logto.io/docs/tutorials/get-started/passwordless-sign-in-by-adding-connectors#enable-social-sign-in).

Once Alipay native connector is enabled, you can build and run your app to see if it works.

## 在你的应用中启用支付宝原生登录

### iOS

我们假设你已经在你的应用中集成了 [Logto iOS SDK](https://docs.logto.io/docs/recipes/integrate-logto/ios)。之后的流程很简单，你甚至不需要阅读支付宝 SDK 文档：

**1. 添加 `LogtoSocialPluginAlipay` 到你的 Xcode 工程**

添加 framework：

![Add framework](/packages/connectors/connector-alipay-native/docs/add-framework.png)

> ℹ️ **Note**
>
> 该插件已包含支付宝极简 SDK。在引入插件后你可以直接使用 `import AFServiceSDK`。

**2. 将插件添加至 `LogtoClient` 的初始化项**

```swift
let logtoClient = LogtoClient(
  useConfig: config,
  socialPlugins: [LogtoSocialPluginAlipay(callbackScheme: "your-scheme")]
)
```

其中 `callbackScheme` 是 [custom URL Schemes](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app) 中之一，它将被用来在登录成功后跳转回应用。

### Android

我们假设你已经在你的应用中集成了 [Logto Android SDK](https://docs.logto.io/docs/recipes/integrate-logto/android)。之后的流程很简单，你甚至不需要阅读支付宝 SDK 文档：

**1. 下载支付宝极简版 SDK 到你的项目中**

从 [Logto 3rd-party Social SDKs](https://github.com/logto-io/social-sdks/blob/master/alipay/android/alipaySdk-15.7.9-20200727142846.aar) 下载支付宝极简版 SDK 到项目的 `app/libs` 目录下:

```bash
project-path/app/libs/alipaySdk-15.7.9-20200727142846.aar
```

**2. 添加支付宝极简版 SDK 为项目依赖项**
