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 associated with the credit card) as usual in the payment payload.

• During connection setup in the DEUNA Admin, a per-merchant setting determines whether DEUNA should normalize the addresses before forwarding them to the processor.

  • Select the "Keep Original Address" option: DEUNA skips its internal normalization step and forwards the fields exactly as provided, including the country code in the format received.
  • "Keep Original Address" not selected (default): DEUNA runs the address through its 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 this behavior, go to the DEUNA Admin and select "Keep Original Address" if you do not want DEUNA to normalize the addresses you send.

• If you want DEUNA to normalize your addresses, no action is required, as this is the default behavior.
