Liqpay Payment Module for OpenCart

The LiqPay Module is a convenient solution for enabling payments through the LiqPay API 3.0 in your online store. Customers can pay for their orders using bank cards from any bank directly on the secure LiqPay payment page, while you automatically receive notifications about the payment status.

The LiqPay payment module integrates seamlessly into the standard checkout process of OpenCart and correctly handles successful, failed, and pending payments.

Main Features

• Transfer of order data to LiqPay (order ID, amount, currency, description).
• Support for API 3.0 (checkout).
• Automatic verification of payment signature and status.
• Handling payment statuses: success, failure, error, wait.
• Flexible configuration of order statuses for successful, failed, and pending payments.
• Geo-zone restriction support.
• Minimum order amount to enable the payment method.
• Payment page language selection (RU, UK, EN).
• Sort order configuration in the list of payment methods.

How the Module Works

After confirming the order, the customer is redirected to the secure LiqPay payment page. The module generates an encrypted data package (base64 + digital signature) and sends:

• Merchant ID (Public Key);
• Private signature (Private Key);
• Order amount and currency;
• Customer email and order number;

After the payment is completed, the store automatically updates the order status according to the response from the payment system.

Advantage for store owners: full automation of payment processing and minimal need for manual order verification.
Advantage for customers: secure and familiar card payment with any bank.

Setup

Setting up LiqPay in OpenCart takes just a few minutes:

1. Enter your Public Key (merchant ID).
2. Provide the Private Key (signature).
3. Verify the API URL (already filled in by default).
4. Configure order statuses and the geo-zone.
5. Enable the module and save the changes.

This module is perfect for Ukrainian and international stores that need to quickly connect online acquiring without complex development. Reliable, secure, and fully compatible with the standard OpenCart architecture.

Unlike the standard module, this LiqPay integration correctly detects the payment status and sets the appropriate order status.
The default LiqPay module always assigns the same order status even if the customer cancels the payment or has insufficient funds.
