AP2 Payment Challenge & Step-Up
Implements secure authentication challenges and step-up flows for agentic payment protocols, including 3DS2 and OTP verification.
This skill enables developers to integrate robust security mechanisms into agentic commerce systems using the AP2 protocol. It provides standardized patterns for handling 3DS2, One-Time Passwords (OTP), and redirect challenges by facilitating secure handoffs between AI agents and trusted authentication surfaces. By ensuring sensitive authentication occurs outside the agent conversation, it maintains high security standards while supporting complex multi-agent payment orchestration and reducing friction in automated transactions.
