Checkout for Shopware
This guide describes how to install, configure, and use the Checkout webshop module for Shopware 5.
Before you start
Before you start, you need an Checkout Portal account. See the guide Create account for more information about creating a free test account.
Shopware 5 has announced an end-of-support and end-of-life, in place from July 2024.
This means that Checkout is no longer actively supporting Shopware 5 with any new security patches or features. This can also affect your PCI DSS (Payment Card Industry Data Security Standard) compliance. For this reason, we recommend that you migrate or upgrade to Shopware 6.
