OneLink API 2.0: The new deep linking infrastructure built for growth and scale

The article highlights the shift to multi-channel and programmatic growth in 2025, where owned-media conversions grew 67% and web-to-app journeys over 250%.
Manual link creation can no longer scale, making deep linking critical infrastructure.
AppsFlyer's OneLink API 2.0 addresses this by enabling programmatic QR generation, custom time-to-live controls for secure flows, and an upgraded developer experience.
Key use cases include QR code integration across CTV, retail, and print; personalized CRM journeys that boost spending and LTV; and secure authentication with short-lived links.
Brands like Albertsons saw a 113% increase in marketing-driven app traffic and 1.2 million QR visitors in two months, while Apartment List achieved a 2× increase in Day 0 logins and 30% higher LTV.
The API ensures scale, context, and governance across all channels, supporting AI-driven workflows.
Investing in a smart linking layer is essential for converting users and maintaining competitive advantage.
