WhatsApp Business is WhatsApp's offering for businesses to communicate with customers. The WhatsApp Business app is aimed at small businesses that manage customer conversations personally. The WhatsApp Business Platform is aimed at medium to large businesses that communicate with customers at scale through programmatic access (API), with message categories such as marketing, authentication, utility and service, and WhatsApp Flows. Both are delivered as cloud services and cannot be self-hosted.
WhatsApp Business is operated by WhatsApp LLC, part of Meta, a US company, so the service falls under US jurisdiction, including the CLOUD Act. For European businesses, WhatsApp Ireland Limited acts as processor under the published data processing terms. European data is transferred to WhatsApp LLC and Meta Platforms, Inc. under the EU-U.S. Data Privacy Framework, and WhatsApp may engage other Meta companies and third parties as sub-processors. WhatsApp documents no EU-only storage option. For a European organisation, this means message data can be processed in the United States.
