# 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.

## Fields
- `issuerAuthenticationData` (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)
- `issuerScriptTemplate1` (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)
- `issuerScriptTemplate2` (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)
- `authorizationResponseCode` (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)
- `rawTlv` (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)
