# Activating the Wi-Fi via Weixin Plug-in

To call all other APIs of Wi-Fi via Weixin, you must activate the "Wi-Fi via Weixin" plug-in by using either of the following ways: (1) Add the Wi-Fi via Weixin plug-in on the Weixin Official Accounts Platform by performing relevant operations. (2) Activate the plug-in by calling this API.

Note: Since the activated plug-in can only be called by third-party platforms, Official Accounts developers need to activate the plug-in on the Weixin Official Accounts Platform. For information on how to access a third-party platform, please see the Weixin Open Platform.

# 3. Guide User to the Plug-in Activation Page

The third-party platform can add the entry to "Activate Wi-Fi via Weixin" in its webpage to guide users to the plug-in activation page. It is recommended to allow users to open the plug-in activation page over the current page.

URL: https://wifi.weixin.qq.com/biz/mp/thirdProviderPlugin.xhtml?token=xxxx, where the third-party platform needs to provide the obtained wifi_token.

# 4. User Enters Information and Activates Plug-in

The user needs to enter relevant information on the plug-in activation page to activate the plug-in.

# 5. Redirect to callback_url

After the plug-in is activated, the page automatically redirects to the callback_url provided when the third-party platform calls the "Get Plug-in's wifi_token" API to complete the activation process. Then, the third-party platform can call other APIs to provide the Wi-Fi via Weixin service for users.
