// Verifies Authorization Request Cryptogram (ARQC) for a EMV chip payment card
// authorization. For more information, see Verify auth request cryptogram (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/data-operations.verifyauthrequestcryptogram.html)
// 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 (https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_ImportKey.html)
// . This operation uses the imported ARQC and an major encryption key (DUKPT)
// created by calling CreateKey (https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_CreateKey.html)
// 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 (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/keys-validattributes.html)
// and Key types for specific data operations (https://docs.aws.amazon.com/payment-cryptography/latest/userguide/crypto-ops-validkeys-ops.html)

// This operation can't be used across different Amazon Web Services accounts.
