WhatsApp plans to collaborate with other messaging apps, allowing seamless chatting across platforms. Learn more about this feature
WhatsApp is preparing a significant update to enable its 2 billion users to message individuals on different platforms, eliminating the need for multiple app downloads. This marks a groundbreaking shift for the platform, previously known for its closed ecosystem. In an interview with Wired, Dick Brouwer, an engineering director at WhatsApp, has outlined the platform’s strategy for interoperating with other messaging apps.
Although there’s no official launch schedule yet, WhatsApp has announced that it will provide more details about its plans next month. In the meantime, here’s an overview of everything the platform has in store for the future of messaging.
Interoperability has been in development for two years
As per Brouwer, the company has been developing interoperability for approximately two years. This development coincides with WhatsApp’s parent company, Meta, being classified as a ‘gatekeeper’ company under the EU’s Digital Markets Act, mandating the opening of its messaging services within six months.
Initially, there will be no group chats or calls
Interoperability will enable WhatsApp users to share messages, images, videos, and files with individuals on different messaging platforms. Brouwer stated that the initial focus will be on one-on-one messaging, rather than group chats or calls. Users will need to opt in to use this feature. Notably, WhatsApp will keep messages from other apps separate; they will be displayed in a ‘third-party chats’ section rather than the main inbox. This approach is aimed at maintaining WhatsApp’s stringent privacy standards.
There is a “real tension” in balancing access with security
Enabling cross-platform messaging presents technical challenges, particularly for encrypted apps like WhatsApp. Various platforms employ different protocols and adhere to diverse privacy standards. Brouwer acknowledged the “real tension” in balancing access and security. WhatsApp plans to release technical specifications in March for third-party integration with its system. Companies must sign an agreement and adhere to WhatsApp’s terms to connect their apps.
Signal’s encryption protocol is the most favored
WhatsApp prefers that third parties use the same Signal encryption protocol as WhatsApp, which is also used by publicly available apps like Google Messages and Skype. To send messages, apps will need to encrypt using Signal and package content into XML message formats. For message reception, they will need to connect to WhatsApp’s servers.
Brouwer stated that this architecture, leveraging WhatsApp’s existing client-server system, is the “best approach.” WhatsApp has been collaborating with other companies and will document its protocols to enable direct integration by third-party clients. There will also be options for proxies between their apps and WhatsApp’s server for developers seeking more flexibility.
It appears to be challenging to persuade other apps to establish connections
Currently, WhatsApp has not disclosed which platforms might participate in the linkage. Major messaging apps such as Telegram, Signal, Snap, and Google have not commented on their plans regarding WhatsApp interoperability. Due to the technical complexities involved, it might take some time for third parties to implement integrations after WhatsApp publishes its guidance in March.
The EU requires interoperability to be implemented within six months
According to EU regulations, interoperability must be launched within a six-month timeframe. However, it remains uncertain whether it will initially be limited to Europe. WhatsApp has not clarified whether the feature will be globally available. Once activated, users will see a “third party chats” section, as previously observed in WhatsApp beta versions by WABetaInfo, although this page is currently not directly accessible or functional.
Will iMessage also open up?
Apple’s iMessage might also need to provide interoperability as per the EU’s Digital Markets Act. However, Apple has not provided any comments on its plans. In the US, there is separate scrutiny regarding the maintenance of iMessage as a closed platform. Opening it up could enhance communication between iOS and Android users.
Summing up…
In summary, WhatsApp’s upcoming changes are substantial. If services are interconnected, users won’t require multiple apps to message various contacts. However, the adoption of these changes hinges on third-party integration, which could be time-consuming due to its complexities. It’s also crucial to address any privacy risks that may arise from lower security standards.
