WeChat social identity provider

Social authentication is deprecated and will be removed in a future release of IDM. For more information, see Deprecation.

These procedures assume that you have a WeChat developer account with access to create WeChat web application credentials. To verify access, you’ll need the WeChat app on your mobile device.

Set up WeChat

To set up WeChat as a social identity provider, you’ll need to get the following information for your WeChat app. The name may be different in WeChat.

Client ID (WeChat uses appid as of this writing.)
Client Secret (WeChat uses secret as of this writing.)
Scope
Authorization Endpoint URL
Token Endpoint URL
User Info Endpoint URL
Redirect URI, normally something like http://openidm.example.com/

WeChat unique requirements

Before testing WeChat, be prepared for the following special requirements:

WeChat works only if you deploy IDM on one of the following ports: 80 or 443.

For more information on how to configure IDM to use these ports, see Host and port information.
For registration and sign-in, WeChat requires the use of a mobile device with a QR code reader.
For sign-in, you’ll also need to install the WeChat app on your mobile device.

Configure a WeChat social identity provider

To configure a WeChat social identity provider using the admin UI:

From the navigation bar, click Configure > Social ID Providers.
On the Social Identity Providers page, enable WeChat.
In the WeChat Provider window, enter applicable values in the fields, and click Save. For a complete list of fields, see WeChat Social Identity Provider Configuration Details.

After you save the social identity provider configuration, IDM generates a conf/identityProvider-wechat.json file:

{
    "provider" : "wechat",
    ...
    "clientId" : "<someUUID>",
    "clientSecret" : {
       "$crypto" : {
           "type" : "x-simple-encryption",
              "value" : {
               "cipher" : "AES/CBC/PKCS5Padding",
               "stableId" : "openidm-sym-default",
               "salt" : "<hashValue>",
               "data" : "<encryptedValue>",
               "keySize" : 16,
               "purpose" : "idm.config.encryption",
               "iv" : "<encryptedValue>",
               "mac" : "<hashValue>"
           }
       }
    },
    "authorizationEndpoint" : "https://open.weixin.qq.com/connect/qrconnect",
    "tokenEndpoint" : "https://api.wechat.com/sns/oauth2/access_token",
    "refreshTokenEndpoint" : "https://api.wechat.com/sns/oauth2/refresh_token",
    "userInfoEndpoint" : "https://api.wechat.com/sns/userinfo",
    "redirectUri" : "http://openidm.example.com:8080/",
    "scope" : [
        "snsapi_login"
    ],
...

The file includes schema information, which includes properties for each social identity account, as collected by IDM, as well as the order in which it appears in the admin UI. When you’ve registered a user with a WeChat social identity, you can verify this by selecting Manage > WeChat, and then selecting a user.

Another part of the file includes a propertyMap, which maps user information entries between the source (social identity provider) and the target (IDM).

If you need more information about the properties in this file, refer to the following appendix: WeChat Social Identity Provider Configuration Details.

Configure user registration to link to WeChat

Once you’ve configured the WeChat social identity provider, you can activate it through User Registration. To do so in the admin UI, select Configure > User Registration, and activate that feature. Under the Social tab that appears, enable Social Registration. For more information on IDM user self-service features, see Self-service end user UI.

When you enable Social Registration, you’re allowing users to register on IDM through all active social identity providers.

You can set up the WeChat social identity provider through the admin UI or in a conf/identityProvider-wechat.json file. IDM generates the identityProvider-wechat.json file when you configure and enable this social identity provider in the admin UI. Alternatively, you can create the file manually.

The following table includes the information shown in the admin UI WeChat Provider pop-up window, along with associated information in the identityProvider-wechat.json file.

WeChat supports URLs on one of the following ports: 80 or 443. For more information on how to configure IDM to use these ports, see Host and port information.
