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.
Not sure where to begin with the new SDK? See Where do I start?. Within each platform’s SDK, Yuno offers various integration methods allowing varying degrees of control over the UI and user experience. The integration method you select affects the level of maintenance effort required. It also determines how you manage payment methods, which may range from no-code configuration in the Yuno Dashboard to hands-on developer work. Some integration types also require certifications such as PCI-DSS or ISO, which affects your compliance obligations.
Recommended IntegrationYuno recommends using Seamless SDK for its flexibility and ease of integration. It provides pre-built UI components while giving you full control over the payment experience and automatic payment method display.
