In line with the changes dictated by SEPA Credit Transfer, published by the European Payments Council, on November 20, 2023, we will change the method of receiving the address for the recipient in foreign transfers.

Detailed information about changes for /EEA, /nonEEA endpoints and for transfer batches in the areas regarding EEA and nonEEA transfers, are included in the detailed documentation on our website. IMPORTANT: We do not change domestic transfers (/domestic)!
