Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-11-12 05:58 UTC.

`EmvIssuerResponseData`

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

The issuer's EMV response to an online chip authorization: the data a terminal hands back to the card to complete the transaction. After an online authorization the chip expects the issuer's authentication data and any issuer scripts before it produces its final cryptogram, so a terminal application reads these values from the transaction response and passes them to its EMV kernel.

Values

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Fields

Field Type Description

issuerAuthenticationData required

string

Issuer authentication data, EMV tag `91`: the value only, as hexadecimal. The terminal passes it to the card so the card can authenticate the issuer's response. Null when the issuer returned none. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

issuerScriptTemplate1 required

string

Issuer script template 1, EMV tag `71`: every template of this kind the issuer returned, each with its tag and length, concatenated in the order received, as hexadecimal. The terminal runs these scripts before the final GENERATE AC. Null when the issuer returned none. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

issuerScriptTemplate2 required

string

Issuer script template 2, EMV tag `72`: every template of this kind the issuer returned, each with its tag and length, concatenated in the order received, as hexadecimal. The terminal runs these scripts after the final GENERATE AC. Null when the issuer returned none. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

authorizationResponseCode required

string

Authorization response code, EMV tag `8A`: the value only, as hexadecimal (two ASCII characters, so an approval reads `3030`). Null when the processor didn't return the tag. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

rawTlv required

string

The complete EMV response data the processor returned, as hexadecimal TLV. It includes the tags above and any other tag the processor sent. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
