To verify a digital signature for agentic payment mandates, use this framework to validate the SD-JWT with Key Binding. It confirms that the Cart Mandate was signed by the user with a hardware-backed key and is tamper-evident for the payment processor.

SD-JWT with Key Binding is a format for verifiable credentials that enables selective disclosure and holder binding. It ensures credentials are cryptographically signed, tamper-evident, and bound to the holder's hardware-backed key for secure presentation.

Manage the lifecycle of verifiable digital credentials by handling their creation, signing, presentation, verification, usage, and archival. This framework supports the full VDC lifecycle aligned with W3C standards for Verifiable Credentials.

Yes, the AP2 VDC framework works with the Payment Request API. It aligns with W3C standards for Verifiable Credentials to ensure secure, cryptographically signed payment authorization and verification during agentic transactions.

You need verifiable credentials for payment authorization when integrating with AP2 to ensure all payment mandates are properly issued, signed by the user with a hardware-backed key, and can be reliably verified by the payment processor.
