# WeChat native connector
|
||
|
||
The official Logto connector for WeChat social sign-in in native apps (iOS and Android).
|
||
|
||
微信原生应用社交登录官方 Logto 连接器（iOS 和 Android）[中文文档](#微信原生连接器)
|
||
|
||
## Get started
|
||
|
||
If you don't know the concept of the connector or haven't add this connector to your Sign-in experience yet, please see [Logto tutorial](https://docs.logto.io/docs/tutorials/get-started/enable-social-sign-in).
|
||
|
||
In native apps, you cannot use the web as a sign-in method of WeChat. Navigation to WeChat is required, and it also requires using their SDK.
|
||
|
||
We know it sounds scary, but don't worry. We'll handle it easily in this tutorial.
|
||
|
||
## Create a mobile app in the WeChat Open Platform
|
||
|
||
> **Note**
|
||
>
|
||
> You can skip some sections if you already finished.
|
||
|
||
### Create an account
|
||
|
||
Open https://open.weixin.qq.com/, click the "Sign Up" button in the upper-right corner, then finish the sign-up process.
|
||
|
||
### Create a mobile app
|
||
|
||
Sign in with the account you just created. In the "Mobile Application" (移动应用) tab, click the big green button "Create a mobile app" (创建移动应用).
|
||
|
||
|
||
|
||
Let's fill out the required info in the application form.
|
||
|
||
|
||
|
||
### Basic info
|
||
|
||
Most of them are pretty straightforward, and we have several tips here:
|
||
|
||
- If you just want to test WeChat sign-in and the app is not on the App Store, in the "App is available" section, choose "No" to skip the "App download link".
|
||
- The "App operation flow chart" looks tricky. From our experience, you need to prepare a simple flowchart and several app screenshots to improve the possibility of passing the review.
|
||
|
||
Click "Next step" to move on.
|
||
|
||
### Platform info
|
||
|
||
Check "iOS app" (iOS 应用), then check the target device type of your app accordingly.
|
||
|
||
|
||
|
||
If you chose "No" for the App Store availability, you cloud skip filling out "AppStore download address" here.
|
||
|
||
Fill out _Bundle ID_, _Test version Bundle ID_, and _Universal Links_ (actually, only one link is needed 😂).
|
||
|
||
> **Note**
|
||
>
|
||
> _Bundle ID_ and _Test version Bundle ID_ can be the same value.
|
||
|
||
> **Warning**
|
||
>
|
||
> WeChat requires Universal Link for native sign-in. If you haven't set up or don't know it, please refer to the [Apple official doc](https://developer.apple.com/ios/universal-links/).
|
||
|
||
Click "Submit Review" to continue.
|
||
|
||
### Waiting for the review result
|
||
|
||
Usually, the review goes fast, which will end within 1-2 days.
|
||
|
||
We suspect the reviewer is allocated randomly on each submission, and the standard is floating. You may get rejected the first time, but don't give up! State your status quo and ask the reviewer how to modify it.
|
||
|
||
## Compose the connector JSON
|
||
|
||
After passing the review, go to the application details page and generate an AppSecret. Compose the connector JSON with the following format:
|
||
|
||
```json
|
||
{
|
||
"appId": "wx123456789",
|
||
"appSecret": "some-random-string",
|
||
"universalLink": "https://your.universal.link/path/"
|
||
}
|
||
```
|
||
|
||
## Add the Logto social plugin to your app
|
||
|
||
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 WeChat SDK doc:
|
||
|
||
**1. Add `LogtoSocialPluginWechat` to your Xcode project**
|
||
|
||
Add the framework:
|
||
|
||
|
||
|
||
And add `-ObjC` to your Build Settings > Linking > Other Linker Flags:
|
||
|
||
|
||
|
||
**2. Add the plugin to your `LogtoClient` init options**
|
||
|
||
```swift
|
||
let logtoClient = LogtoClient(
|
||
useConfig: config,
|
||
socialPlugins: [LogtoSocialPluginWechat()]
|
||
)
|
||
```
|
||
|
||
**3. Handle `onOpenURL` properly**
|
||
|
||
> **Note**
|
||
>
|
||
> The function `LogtoClient.handle(url:)` will handle all the native connectors you enabled. You only need to call it once.
|
||
|
||
```swift
|
||
// SwiftUI
|
||
YourRootView()
|
||
.onOpenURL { url in
|
||
LogtoClient.handle(url: url)
|
||
}
|
||
|
||
// or AppDelegate
|
||
func application(_ app: UIApplication, open url: URL, options: /*...*/) -> Bool {
|
||
LogtoClient.handle(url: url)
|
||
}
|
||
```
|
||
|
||
That's it. 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).
|
||
|
||
After WeChat native connector is enabled, you can build and run your app to see if it works.
|
||
|
||
> **Note**
|
||
>
|
||
> WeChat doesn't have a plan for those devices without the WeChat app installed. Logto will hide this connector during sign-in if so (which is the recommended way from the [official development guide](https://developers.weixin.qq.com/doc/oplatform/en/Mobile_App/WeChat_Login/Development_Guide.html)).
