verifyAuthRequestCryptogram

Verifies Authorization Request Cryptogram (ARQC) for a EMV chip payment card authorization. For more information, see Verify auth request cryptogram in the Amazon Web Services Payment Cryptography User Guide.

ARQC generation is done outside of Amazon Web Services Payment Cryptography and is typically generated on a point of sale terminal for an EMV chip card to obtain payment authorization during transaction time. For ARQC verification, you must first import the ARQC generated outside of Amazon Web Services Payment Cryptography by calling ImportKey. This operation uses the imported ARQC and an major encryption key (DUKPT) created by calling CreateKey to either provide a boolean ARQC verification result or provide an APRC (Authorization Response Cryptogram) response using Method 1 or Method 2. The ARPC_METHOD_1 uses AuthResponseCode to generate ARPC and ARPC_METHOD_2 uses CardStatusUpdate to generate ARPC.

For information about valid keys for this operation, see Understanding key attributes and Key types for specific data operations in the Amazon Web Services Payment Cryptography User Guide.
