This page documents a legacy SDK. Starting a new integration? Use the Yuno SDK. Already on a legacy SDK? Follow the migration guide.The new Yuno SDK (Web v2.x, iOS v3.x, Android v3.x) replaces the Full, Lite, Seamless, Render, Headless, and Secure Fields SDKs with one API across every platform. Legacy SDKs remain supported side by side during the transition and are scheduled for deprecation in 2027. Contact your Account Manager for migration planning.
Yuno’s secure-fields provide a way to securely collect sensitive payment information while maintaining PCI compliance. This approach allows you to build custom user interfaces while keeping sensitive data secure. For SDK setup, see Quickstart guide.
