Tencent's (0700.HK) mobile messaging app Weixin recently began opening API ports to add support for third-party application connectivity. Third-party developers can apply for developer accounts to receive API authorization to develop application support for the service. Wexin has already added interactivity between Tencent properties including QQ Instant Messenger, QQ Mail, Tencent Microblog, and Tencent News. On April 24, online fashion community Meilishuo.com announced that it would allow its users to share content directly with their Wexin contacts as one of the first third-party applications to launch for the service.
According to official figures from Tencent, there are currently more than 120 mln registered Wexin users.
