Deprecated
Deprecation of legacy iFrame and non-secure tokenization
November 2nd, 2026
As of October 31, 2026, legacy iFrame (version 1.140 and older) and non-secure tokenization are deprecated. End of life is December 31, 2028.
What this means for you
Nothing changes in how tokenization works today, and no action will break your current integration. Deprecated integrations receive only critical bug fixes, security fixes, and updates needed for PCI DSS compliance. New features and enhancements are delivered only on the Checkout SDK.
Recommended path
We recommend migrating to the Checkout SDK, available for Web, iOS, Android, and React Native. It offers Headless (Hosted Fields) and Express integration paths. Your account team can help plan your migration and answer questions about your integration.
