Questions and answers about the Sylius integration
Is there a Payrexx plugin for Sylius?
A Payrexx checkout plugin is available for Sylius, developed by the agency Comvation and provided on GitHub. It integrates Payrexx via the Payum gateway system of Sylius, so that the payment remains part of the shop's regular state machine. You can find the download and installation steps in the Payrexx documentation.
How do I integrate the Payrexx plugin into Sylius?
You download the plugin as a ZIP file from the GitHub repository and follow the steps in the included README file to install it in your Sylius project. Afterwards, you store the instance name and API key from your Payrexx Comerciante administration in the gateway configuration. The complete instructions are described in the Payrexx documentation.
Do I need developer skills for the Sylius integration?
The installation of the plugin is specifically aimed at developers with experience in the Symfony framework and not at end users. Since Sylius is a framework and not an out-of-the-box shop system, the setup is done via the project structure and the configuration of the shop. No programming knowledge is required for ongoing operations thereafter.
Which functions does the Payrexx plugin for Sylius offer?
The plugin supports multi-currency capability, the display of payment method logos in the checkout, as well as an individual configuration of the offered payment methods. In addition, the look and feel of the payment page can be customized and webhooks can be set up, which report the payment status back to Sylius.
Which payment methods does the Sylius plugin support?
Through Payrexx, all relevant payment methods are available in the Sylius checkout with a single acceptance contract: Mastercard, Visa, AMEX, Maestro, PayPal, Apple Pay, TWINT, Google Pay, Samsung Pay, PostFinance Card, Invoice, bank transfer, Centi, HeidiPay, WIRpay, Masterpass, Reka, and Klarna. You determine which methods appear in the checkout in the plugin configuration and in your Payrexx account.
Does the sylius plugin support multiple currencies?
Multi-currency capability is a core feature of Sylius and is supported by the Payrexx plugin. This allows you to operate international shops and offer prices in multiple currencies, while payment processing continues to run centrally via Payrexx.

How are the funds from sylius transactions paid out?
Payrexx pays out the payments received via your Sylius shop directly to your deposited bank account. The payout takes place at regular intervals, with transaction fees already deducted. You can find out how payouts work in detail in our documentation.
How secure is Payrexx for Comerciantes?
If you integrate Payrexx into your Sylius shop, every transaction is secured according to the highest global security standard for payment data: Payrexx is fully PCI DSS Level 1 certified. Personal data, both yours and that of your customers, is stored in a GDPR-compliant manner. The 3-D Secure process adds an additional layer of identification to payments, thereby minimizing fraud risks and chargebacks.
