vads_initial_issuer_transaction_identifier

Description Unique transaction reference generated by the issuer.

Called a "chaining reference", it is used under PSD2 for processing MIT transactions to indicate to the issuer that the transaction is part of a series of payments for which the cardholder authenticated himself in the first payment.

Without this information, the issuer can refuse an MIT transaction for lack of authentication (soft decline).

Output field, returned in the response (IPN and Return URL).
