PostFinance Pay for PrestaShop

PostFinance Pay is the established payment solution from PostFinance. Combined with PrestaShop, the open-source shop system with a large community, you offer your customers exactly the payment option they expect at checkout. With zahls.ch you connect the two without any coding: create an account, set up the integration, activate PostFinance Pay. It then appears directly in the checkout of your PrestaShop store, and all transactions are gathered clearly in your dashboard.

PrestaShop is an open source shop system with a large community and thousands of modules. You host the store yourself, keeping full control over data, design, and extensions.

To connect it to zahls.ch, download the official zahls module from GitHub, install it in the PrestaShop back office, link it with your API keys, and activate the payment methods you want at checkout.

The payment status is passed to the order automatically; refunds and reporting are handled in the zahls.ch dashboard.

PrestaShop suits merchants who prefer a free open source foundation and want to grow their store step by step with modules.
