What it does
This add-on connects your CS-Cart checkout to the Payrexx payment gateway. Customers are redirected to a secure Payrexx payment page and then returned to your store after payment completion. Payment results are synchronized through callback notifications, so order statuses stay accurate without manual checks.
Key features
- Accepts Payrexx payments - processes online payments through your Payrexx instance directly from checkout.
- Synchronizes statuses automatically - updates CS-Cart order status based on Payrexx transaction state.
- Supports webhook flow - handles asynchronous callbacks for reliable payment confirmation.
- Controls capture strategy - enables pre-authorization, charge-on-authorization, and reservation modes.
- Filters available methods - limits payment providers (PSP) and payment means according to your needs.
- Logs API request failures - records failed gateway requests for easier troubleshooting.
How it works
- Configure credentials - set your Payrexx instance name and API key in payment method settings.
- Set webhook URL - add the callback URL in your Payrexx Webhooks section.
- Process payments - customer pays on Payrexx, then the add-on applies returned payment status to the order.
Requirements
- Active Payrexx merchant account
- Valid Payrexx API key and configured webhook endpoint
