Liqpay API Opencart - online payment for Opencart 3 and 2.x, OcStore 3 and 2.х.

Liqpay API — online payment — is a fully functional integration of the LiqPay payment system for online stores on OpenCart 3.x / ocStore 3.x. The module allows you to accept online payments from customers conveniently, securely and flexibly — from standard card payments to Apple Pay, Google Pay and fiscalized receipts.

The package consists of three related modules:

• Main module — a full-fledged payment method via LiqPay (standard payment or embedded widget).
• Prepayment — a separate method for partial payment (fixed amount or percentage of the order).
• eSupport — a copy of the main module with separate API keys, designed to accept payments under the eSupport state program (or any other alternative LiqPay account).
