Description

The Paymill processes credit card payments directly in the WooCommerce checkout, integrating the Paymill API to authorize transactions without redirecting the customer outside the store. The gateway completes the purchase on the checkout page itself and is aimed at those who sell in European markets served by Paymill and want to keep the payment flow within the store’s domain.
