Connect your shop system to the PostFinance payment solution

PostFinance offers free plug-ins for numerous shop systems that are widely used in Switzerland: Shopware, WooCommerce, Magento 2, OpenCart, PrestaShop, OXID and JTL. Third-party plug-ins are available for other systems (e.g. Drupal Commerce, nopCommerce, Joomla/VirtueMart), and SaaS solutions such as Shopify, Wix or Hostpoint can be connected directly via connected services.

A PostFinance plug-in is an extension provided by PostFinance for certain shop systems. Third-party plug-ins originate from external providers or communities and can be used if PostFinance does not offer its own plug-in for the shop system. Connected services connect SaaS shop solutions, e.g. Shopify or Wix, directly with the PostFinance payment solution without the need to install a traditional plug-in in your own shop.
