Alipay Native

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

Create and configure Alipay app

Sign in to the Alipay console with the account you have just registered.
Go to Web & Mobile Apps tab in My Application panel.
Click Create an App button to start configuring your application.
Name your application in Application Name following the naming conventions and upload your Application Icon, make sure you choose mobile application as App type. For building iOS App, a unique bundle ID is required. Also, application signature and application package name are required for Android apps.
After finishing creating the application, we come to the Overview page, where we should click add ability to add Third-party application authorization, Get member information and App Alipay login before enabling Alipay sign-in.
Go to Alipay Customer Center, and sign in with the Alipay developer account. Click Account Center on the top bar and go to APPID binding, whose entrance can be found at the bottom of the sidebar. Add binding by type in the APPID of the mobile application you just created in step 4. After finishing this step, you are expected to find abilities you have just added in step 5 kicks in.
Come back to Alipay open platform console page, and you can find Interface signing method in development information section. Click set up button, and you can find yourself on a page setting signing method. Public Key is the preferred signing mode, and fill in contents from the public key file you have generated in the text input box.
Set up Authorization Redirect URI by clicking set up button on the bottom of the Alipay console page. ${your_logto_origin}/callback/alipay-native is the default redirect URI used in Logto core.
After finishing all these steps, go back to the top right corner of Alipay console page, and click Submit for review. Once the review is approved, you are good to go with a smooth Alipay sign-in flow.

Set up the Logto Alipay Native connector settings

In the Alipay console workspace go to My application panel and click Web & Mobile Apps tab, you can find APPID of all applications.
In step 7 of the previous part, you have already generated a key pair including a private key and a public key.
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. Remember to use '\n' to replace all newlines.
- 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'

iOS

We assume you have integrated Logto iOS SDK 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:

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

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

Where callbackScheme is one of the custom URL Schemes that can navigate to your app.

Android

We assume you have integrated Logto Android SDK 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 to your project's app/libs folder:

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

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

Open your build.gradle file:

project-path/app/build.gradle

Add the dependency:

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.

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