Description:
Meta Offline Conversions API (Offline CAPI) allows businesses to send offline event data—such as in-store purchases, phone orders, or other offline interactions—directly to Meta. This enables the measurement and optimization of ads beyond online touchpoints by linking offline conversion data with Meta ad campaigns. The Offline CAPI helps advertisers understand the true impact of their ads across the customer journey, improve attribution accuracy, and enhance targeting, all while maintaining user privacy through secure, server-to-server data transmission.
