16:05GDPR & EU Compliance
Can EU companies use WhatsApp Cloud API under GDPR?
GDPR compliance for WhatsApp depends on your architecture: who processes message content, where it flows, and what each party stores. Dualhook's direct-routing approach keeps message data between Meta and your server, which simplifies the compliance picture for EU teams.
- Belgian company
- Zero message storage
- Direct Meta webhooks
Dualhook does not store or use WhatsApp message content as part of its service. Meta routes message-path webhooks directly to your server, while Dualhook focuses on management events and routing diagnostics.
How does WhatsApp message data flow in a Dualhook setup?
In a standard Dualhook configuration, message-path webhooks flow in a straight line from Meta to your server. Dualhook sits alongside this path as a configuration and operations layer rather than as a shared inbox or message-storage layer.
Compare this with a BSP or shared inbox platform, where message content routes through a third-party server before reaching yours. That additional hop introduces another party into the message data flow, which has direct implications for your GDPR analysis.

How does Dualhook's architecture relate to GDPR roles?
The GDPR framework distinguishes between data controllers and data processors. The specific roles depend on the details of each business relationship and data flow, and the EDPB's guidance on these distinctions is nuanced. Here is how Dualhook's architecture typically factors into that analysis:
- Message content
Message-path webhooks are routed to your server rather than being stored in Dualhook. The relevant parties for ongoing message handling are typically Meta (which operates the WhatsApp platform) and your business (which receives and processes the messages on your own server), while Dualhook focuses on management events and routing diagnostics.
- Operational metadata
Dualhook processes configuration data and operational metadata such as account identifiers, webhook URLs, template metadata, and management event logs. The GDPR role for this processing is defined in Dualhook's data processing agreement.
- Why this matters
Fewer parties processing message content typically means a simpler compliance posture. With Dualhook, you do not need to account for a third-party BSP or inbox provider in your message data flow analysis.
The controller/processor determination for your specific setup depends on your business context and agreements. Consult your data protection officer or qualified legal counsel for definitive guidance.
What Dualhook does not store
- Message text bodies
- Media files (images, video, documents)
- Conversation history or archives
- End-user personal data from messages
What Dualhook does store
- Connection identifiers and configuration state
- Webhook URL and verify-token configuration
- Operational logs for management events
- Health, template, and compliance-oriented metadata
How does this architecture affect data processing agreements?
Because Dualhook is designed around operational metadata and routing configuration rather than conversation storage, the scope of any data processing agreement with Dualhook is narrower than a DPA with a BSP or shared inbox provider, where the agreement typically needs to cover message content, media, and conversation data.
This does not eliminate the need for proper agreements; it narrows the scope of what those agreements need to cover. Your relationship with Meta for the WhatsApp Business Platform is separate and governed by Meta's own data processing terms.

EU businesses operate under some of the strictest privacy regulations in the world. When adopting WhatsApp for customer communication, the choice of architecture directly affects your compliance posture.
- Simpler inbound data flow
Meta sends inbound message webhooks directly to your server. Dualhook's outbound runtime and Cloudflare process supported send requests transiently without storing message content.
- Reduced third-party exposure
No extra vendor sits in the inbound message path, and outbound content is processed only transiently without retention: fewer data processing agreements to manage and fewer parties to audit.
- Belgian roots
Dualhook is a Belgian company built with EU privacy expectations at its core. The zero message storage architecture is not an afterthought; it is the foundational design decision.
- Control over message data
Your messages stay on your server. You decide the retention, access, and security policies for customer conversation data.
