Overview

Block1 CreditReversalReqBlock1Type Complex Type

Contains a series of required and optional elements

Note: CardData, ClientTxnId, and GatewayTxnId are mutually exclusive, but it is required that one of these fields be provided.

Note: Always run reversals with either GatewayTxnId or ClientTxnId. If only CardData is used the results are not guaranteed as the original transaction may not be uniquely identified.

All

GatewayTxnId optional txnIdType Simple Type

ReaderPresent optional booleanType Simple Type

Indicates whether or not a reader was present at the time of the transaction

CVV2 optional Restriction of cvv2Type Simple Type

CVV Number ("Card Verification Value"); 3 digits on VISA, MasterCard, Discover and UnionPay and 4 on American Express.

CVV numbers are also known as CSC numbers ("Card Security Code"), as well as CVV2 numbers, which are the same as CVV numbers, except that they have been generated by a 2nd generation process.

Note: This field is not used for EBT transactions.

CVV2Status optional cvv2Status Simple Type

Indicates why the CVV2 value was not provided; see the associated Type enumerations for specific values supported.

Note: This field is not used for EBT transactions.

EncryptionData optional EncryptionDataType Complex Type

If the supplied card data was encrypted, this must be supplied.

All

DataFormat optional encryptedDataFormatType Simple Type

EncryptionDataFormat is an optional field to be used for encryption Version "05" to define the encryption encoding format

EncryptionDataFormat 1 Denotes the CardData sent to PORTICO is Binary

EncryptionDataFormat 2 Denotes the CardData sent to PORTICO is ASCII

Version encryptionVersionType Simple Type

The encryption version used on the supplied data.

For PAN encryption, use version "02" or "04" for Heartland E3 encryption. This requires the client to parse the E3 MSR output. The encrypted PAN is passed in the card data element as the manual entry card number. The KTB must be provided as part of the encryption data. If sending an encrypted CVV2, use version "04" which expects the PAN and CVV2 to be encrypted.

For PAN encryption, use version "05" for TDES DUKPT encryption with and without CVV encryption. This requires the client to parse the output. The encrypted PAN is passed in the card data element as the manual entry card number. The KSN must be provided as part of the encryption data.

For track encryption, use version "01", "02", or "04" for Heartland E3 encryption. Version "01" will not require parsing and it will not require additional fields in the encryption data, but the full E3 MSR output must be passed in the card data element as track data. Version "02" and "04" requires the client to parse the E3 MSR output. The KTB must be provided as part of the encryption data. In addition, the client must parse the data specific to either encrypted track 1 or track 2 and provide this in the card data element as track data as well as supply the track number as EncryptedTrackNumber.

For track encryption, use either version "03" for AES encryption with DUKPT, or "05" for TDES encryption with DUKPT. The "03" option supports the IdTECH card readers. The "05" option will work with any device that supports TDES with DUKPT data encryption per AINSI 9.24-1. Both options require the client to parse reader output. The KSN must be provided as part of the encryption data. In addition, the client must parse the data specific to either encrypted track 1 or track 2 and provide this in the card data element as track data as well as supply the track number as EncryptedTrackNumber.

For track encryption "05" is used for TDES encryption with DUKPT. The "05" option will work with any device that supports TDES with DUKPT data encryption per ANSI 9.24-1. Both options require the client to parse reader output. The KSN must be provided as part of the encryption data. In addition, the client must parse the data specific to either encrypted track 1 or track 2 and provide this in the card data element as track data, as well as supply the track number as EncryptedTrackNumber.

EncryptedTrackNumber optional encryptedTrackNumberType Simple Type

Required for encryption version "02","03","04" and "05"; indicates which track is being supplied encrypted (i.e. "1" or "2").

Not Applicable for Reward Cash transactions.

All

Mapping optional TokenMappingType Simple Type

This indicates the type of token to return; see the associated Type enumerations for specific values supported.

Note: If not supplied, "CONSTANT" is assumed. This means that the same token will be returned for the same card data.

Amt amtTypeGlobal Simple Type

This must match the authorization amount from the original transaction. This is required for both full and partial reversals. If not supplied an error response will be returned.

AuthAmt optional amtTypeGlobal Simple Type

This field is required for a partial reversal and indicates the desired new authorization amount once the reversal has been processed. If not supplied it will be defaulted to zero indicating a full reversal.
