Yes, you can display information on the terminal during a checkout by setting the TerminalCheckout note parameter to the partner name, setting an invoice/order number that is also visible on the partner platform, and setting the reference_id parameter to a unique human-readable reference number. This typically helps in reconciling payments across the partner and Square platforms. However, please note that the Terminal API doesn’t support itemized transactions. Transactions processed with the Terminal API appear on buyer receipts and in the Seller Dashboard with an optional note and the total transaction amount.
