WhatsApp interoperability EU is now entering a new phase, as WhatsApp prepares to connect with the first two third-party messaging apps across Europe. Meta confirmed that BirdyChat and Haiket will soon be able to exchange messages with WhatsApp users. This update follows the requirements of the EU’s Digital Markets Act (DMA) and signals the start of a more open, cross-platform messaging system in the region.
Meta began working on interoperability in 2023. Since then, the company has run several small tests to ensure stable communication between WhatsApp, BirdyChat and Haiket. Because these tests were successful, the rollout will begin across Europe “soon,” according to Meta.
What WhatsApp interoperability EU means for users
When the integration launches, users will be able to send and receive text messages, images, videos, voice notes and files. In addition, the feature will work on both Android and iOS, which ensures a consistent experience across devices.
However, there is an important condition. Any service that connects to WhatsApp must provide end-to-end encryption that meets WhatsApp’s security standards. This requirement is mandatory under the DMA, which aims to protect user privacy even when messages move between different platforms.
WhatsApp users will see a new option in the Settings section once the feature becomes available. There, they will find instructions on how to enable communication with third-party apps. The feature is completely optional, and users can disable it at any time.
Group chats will come later
Earlier this year, Meta released technical documentation explaining how WhatsApp would integrate with other messengers. According to those details, users will eventually be able to create cross-platform group chats with friends using partner apps. Even so, this capability will not be included at launch.
BirdyChat, Haiket and future partner apps need additional development time before group chat support becomes possible. Meta says the feature will roll out once these platforms complete the required technical work.
Why WhatsApp interoperability EU matters for the broader messaging ecosystem
This update is a key milestone for WhatsApp interoperability EU, because it introduces real cross-platform communication for the first time. As a result, the messaging landscape in Europe will look very different. Users will no longer be forced into a single platform just to stay connected with their contacts, which is one of the core goals of the DMA.
The EU designed the law to reduce platform lock-in, increase competition and give consumers more choice. Because WhatsApp is one of the largest messaging services in the region, interoperability has the potential to reshape how millions of people communicate every day.
More third-party apps will be added in the future
Meta made it clear that BirdyChat and Haiket are only the beginning. Under the DMA, WhatsApp must continue expanding its interoperability with additional messaging services over time. Consequently, more apps will join the list in future updates.
As WhatsApp interoperability EU continues to expand, users can expect a more flexible, open and competitive digital environment. This change may also push other large platforms to rethink how they handle messaging in regulated markets.
