How do I link the Mollie payment system to osCommerce?

Mollie facilitates accepting payment methods such as iDEAL, PayPal and credit card in your osCommerce webshop. For this purpose, we have developed a module (plugin) that can be seamlessly integrated into any osCommerce installation.

Please take note: FTP access to your web server is required for the installation of this module. Never done this before? Then let your website builder or server administrator install this module for you.

  1. Download the latest Mollie module for osCommerce ( via our GitHub page:
  2. Upload the 'catalog' folder to the osCommerce installation. Overwrite old files if asked to do so.
  3. Go to the admin environment of osCommerce and use the main menu to navigate to Modules & Payments. In the top right corner, click on the 'Install Module' button. On the drop-down list are several Mollie payment methods. Activate all the necessary payment methods by clicking on the payment method and next on 'Install Module'.
  4. Fill out the API key from your website profile for one of the payment methods. The settings are automatically applied to all Mollie payment methods.

If you want to make some test payments first, use the test key instead of the live key.
