WooCommerce Checkout.fi

Overview

The WooCommerce Checkout (Finland) Payment Gateway plugin extends WooCommerce, allowing you to take payments via the Checkout.fi payment portal. You need to register for a contract with Checkout.fi to use this plugin.

Heads up! We’ve retired this plugin in favor of Paytrail for WooCommerce. Now that the Checkout.fi has merged with Paytrail, they’re offering a new service with an improved payment platform and comprehensive range of payment methods. Learn more here. If you are an existing Checkout.fi customer, you can continue to use this plugin to process your payments until the Checkout.fi service is discontinued in August 2022. We’re migrating you to the new plugin before then to avoid disruptions to your payment processing. Please update your plugin and follow the migration instructions.
