To install Mollie Plus plugin for Craft CMS, follow these steps:

  2. Then tell Composer to load the plugin:
    composer require white-nl/commerce-mollie-plus

You can also install the Mollie Plus plugin using the Plugin Store in the Craft Control Panel. Go to Settings → Plugins and click the “Install” button for Commerce Mollie Plus.

"Mollie Plus" versus "Mollie for Craft Commerce"

Mollie plus is a drop-in replacement* for Pixel & Tonic’s Mollie for Commerce plugin. We advise to replace it by Mollie Plus. It will be a seamless transition, since they function similarly.

* The plugin will run completely independently from the Mollie plugin. You even can run both plugins at the same time.


To add a Mollie payment gateway

  1. Go to Commerce → System Settings → Gateways
  2. Create a new gateway, and set the gateway type to “Mollie Plus”.
  3. You have to provide a valid API Key to make this plugin work. You can obtain it in your Mollie control panel.

Tip: The API Key setting can be set to environment variables. See Environmental Configuration in the Craft docs to learn more about that.

Order status to automatically capture payments

When a Craft order status changes to one of defined statuses, any uncaptured Mollie transactions associated with it are going to be captured automatically.

Add Klarna

To offer Klarna in your checkout, there are no extra plugin settings required. However, make sure you have submitted a request for the Klarna payment methods via the Mollie Control panel.

Mollie Plus supports three Klarna payment methods additionally:

  • Klarna Pay Later
  • Klarna Slice it
  • Klarna Pay Now

Front-end customization

An example payment method selection form comes with the install of the plugin, but can be adjusted to your needs. You can add custom styling, display icons and run custom code.


All responses from Mollie are captured in the transaction list of the order, similar to the original Mollie plugin.

Limited support for refunding of Klarna transactions

Refunding payments via Craft works via the Mollie Payment API, whilst transactions are created via the Orders API. Refunding of arbitrary amounts via Craft control panel for Klarna transactions, may result in unexpected behaviour. We recommend using the Mollie control panel to refund specific lines of an order.

No support for vouchers

Mollie voucher services are not supported by this plugin.
