使用第三方应用程序与 WhatsApp 用户聊天即将实现。Meta 将对第三方应用程序开放这一能力。该公司称，WhatsApp 要求其他聊天应用程序在连接时使用 WhatsApp 自己的协议发送消息。该协议是 Extensible Messaging and Presence Protocol（XMPP）的修改版本。消息的加密必须通过 WhatsApp 使用的 Signal 协议或类似的替代方案进行，与第三方服务器的连接使用 HTTP 进行，数据以 XML 文件的形式进行组织。同时 Meta 表示，在使用第三方应用程序时，无法保证端到端加密的持续性，因为它无法控制线路另一端的应用程序。因此在第三方服务器上可能存在被窃听的风险。开发者可向 Meta 申请互操作性。Meta 开放 WhatsApp 是应 DMA（欧盟数字市场法案）的要求，该法案要求，指定的消息传递服务必须允许第三方消息传递服务实现互操作，前提是第三方满足一系列资格，包括技术和安全要求。WhatsApp 应能够与其他应用程序交换消息、照片、视频和语音备忘录，但群组聊天和视频通话功能尚未实现。参考链接
The ability to chat with WhatsApp users using third-party applications will soon be realized. Meta is opening up this capability to third-party apps. The company states that WhatsApp requires other chat applications to use WhatsApp’s own protocol for message transmission. This protocol is a modified version of the Extensible Messaging and Presence Protocol (XMPP). Message encryption must be done through the Signal protocol used by WhatsApp or a similar alternative. The connection to third-party servers is done via HTTP, with data organized in XML files.
However, Meta acknowledges that when using third-party applications, it cannot guarantee the continuity of end-to-end encryption since it has no control over the application at the other end of the line. Therefore, there may be a risk of eavesdropping on the third-party server, according to the company.
Developers can apply to Meta for this capability. Meta’s opening of WhatsApp is in response to the requirements of the EU Digital Markets Act (DMA), which mandates that WhatsApp allows users to communicate with other applications through its platform. While WhatsApp should be able to exchange messages, photos, videos, and voice memos with other applications, group chats and video calling functionality have not yet been implemented.
