WhatsApp Set to Launch Third-Party Chat Support in the European Union to Meet DMA Compliance
January 7, 2026
=========================================================================================================================
WhatsApp, the popular messaging platform owned by Meta, is preparing to introduce third-party chat support across the European Union as part of its compliance efforts with the Digital Markets Act (DMA). This move signals a significant shift towards interoperability, allowing users to communicate more seamlessly across different messaging services while maintaining security and privacy standards.
Interoperability with BirdyChat and Haiket
Meta has announced that the initial third-party apps to integrate with WhatsApp are BirdyChat and Haiket. After successful testing over recent months, these partnerships will enable WhatsApp users on iOS and Android to share messages, images, voice messages, videos, and files with contacts on these platforms.
Future Features and Limitations
Meta indicated that there will be an option to create groups with third-party users once their partners are ready to support this feature. Currently, the interoperability support appears to be exclusively mobile-focused, with no mention of web or desktop app integration.
Security and Privacy Standards
To ensure security, all third-party messaging apps must employ the same level of end-to-end encryption (E2EE) as WhatsApp. Meta emphasizes that this requirement is to preserve user privacy and security, aligning with the DMA's core principles.
A Collaborative Approach
According to Meta, the partnerships with BirdyChat and Haiket are the culmination of over three years of cooperation with European messaging services and authorities. The goal has been to develop solutions that meet DMA requirements without compromising user privacy and security.
Guidelines and User Experience
Meta outlined three guiding principles for this initiative:
- Protecting user security and privacy: Ensuring third-party apps use equal levels of E2EE.
- Clear and simple user experience: Providing an easy onboarding process that clearly differentiates WhatsApp chats from third-party chats.
- Availability within Europe: Making the feature accessible exclusively to European users, as mandated by the DMA.
User Notifications and Future Expansion
Over the coming months, European WhatsApp users will see notifications within the app settings, guiding them on how to opt-in to connect with third-party services. Meta aims to expand interoperability features further in response to DMA requirements and will update users on new developments as they occur.
Background and Motivation
WhatsApp has been developing interoperability features for several years, with Meta stating that its efforts are driven partly by the DMA and partly by strategic improvements to user experience and cross-platform communication.
Conclusion
The rollout of third-party chat support marks a significant step towards open messaging ecosystems within the European Union, emphasizing security, privacy, and user control.
