Mollie Payments for Shopware 6
by Mollie B.V.
The Mollie Payments Plugin for Shopware 6 is Mollie B.V.'s official open-source extension for integrating its payment services with Shopware 6. It connects your store to your Mollie account using API keys and makes the payment methods enabled there available to customers during checkout.
Configuration takes place directly in the Shopware Administration. Once connected to Mollie, payment methods can be assigned to the required sales channels and validated in test mode before the store goes live. This allows the payment setup to be tailored to the needs of each sales channel.
Beyond payment processing, the extension supports the management of full and partial refunds from the Shopware backend. It also supports modern commerce scenarios through Shopware 6 Flow Builder integration, headless storefronts, Shopware PWA, recurring payments, and Mollie POS terminals.
