Address Normalization

By default, DEUNA normalizes the billing and shipping addresses you send in the payment request before forwarding them to the processor. If your addresses are already normalized on your side, this behavior can be configured per merchant connection.

How it works:

• You send billing_address / shipping_address (and the address tied to the credit card) as usual in the payment payload.
• At connection setup in the DEUNA Admin, a per-merchant setting tells DEUNA whether your addresses already arrive normalized.
  • Normalized address: DEUNA skips its internal normalization step and forwards the fields exactly as sent — including the country code exactly as provided.
  • Not normalized address (default): DEUNA runs the address through an internal normalization service before sending it to the processor. This service may reformat fields — for example, expanding country codes to full country names — to match what the processor expects.
• To configure it, go to the DEUNA Admin and check the "Normalized address" option if you do not want DEUNA to normalize the address you send.
• If you want DEUNA to normalize your address, no action is needed.
