This document presents the steps for integrating the Geidea payment gateway with your OpenCart store.


OpenCart is an online store management system. It is PHP-based, using a MySQL database and HTML components. It is designed for small to large online merchants to set up e-commerce sites seamlessly and quickly. Geidea Payments Online is a gateway plugin that extends OpenCart, allowing you to accept payments through Geidea. You can easily accept credit card payments and other payments through wallet providers or Buy-Now-Pay-Later (BNPL) providers.

Integrating our payment gateway with OpenCart's online stores has never been easier. Through the Geidea Online Payments plugin in our GitHub repository, our payment gateway can be seamlessly integrated with just a few lines of code.


You will need a merchant account with Geidea and the following software running in your hosting environment to accept payments using the Geidea payment gateway.

OpenCart4.0.2.0 or greater
Geidea Online Payments plugin3.1.1
PHP8.2.0 or greater


While we make every effort to test software or module or plugin updates rigorously, there is no guarantee that a plugin or module would work seamlessly with your hosting environment. So please back up your website before updating any plugins or modules. This helps you restore your website from backup in case you run into unexpected errors.

Software and plugin or module updates involve programming code changes. The updates may often request upgrades to the server or other hosting software such as PHP as well.
