Woocommerce CrediMax MPGS Payment Gateway 2.8

WooCommerce CrediMax MPGS Payment Gateway is a specialized WordPress plugin designed for e-commerce stores in the Middle East—particularly in Bahrain—that wish to accept secure online payments via CrediMax, the kingdom's pioneering card issuer.1

The "MPGS" in the name stands for Mastercard Payment Gateway Services, which is the robust global technology infrastructure that CrediMax uses to process transactions.2

## Core Features

Hosted Checkout & Lightbox: You can choose to redirect customers to a secure CrediMax-hosted page or display a "pop-up" lightbox so users never technically leave your site.3

3-D Secure (3DS v2) Support: Fully compliant with modern security standards to reduce fraud and provide "Strong Customer Authentication" (SCA).4

Full Transaction Control: Supports "Authorize and Capture" (holding funds and then capturing them when you ship) as well as direct "Sale" transactions.

Refund Integration: Process refunds or void transactions directly from the WooCommerce order screen without logging into the CrediMax merchant portal.5

WordPress Blocks Support: Compatible with the modern WooCommerce "Checkout Block," ensuring it works with the latest Gutenberg-based themes.6

### Configuration Requirements

To use this gateway, you cannot simply install the plugin; you must have an active merchant agreement with CrediMax. You will need the following credentials from them:

Merchant ID: Your unique business identifier.7

API Password: A secure key to authenticate your site's requests.

MPGS URL: The specific endpoint for CrediMax (typically https://credimax.gateway.mastercard.com).

Webhooks Secret: (Optional) To allow the bank to automatically update order statuses on your site.

### Installation & Setup

Install: Upload the plugin zip file (usually provided by developers like PluginsMaker) via Plugins > Add New.8

Navigate: Go to WooCommerce > Settings > Payments.9

Manage: Locate "CrediMax MPGS" and click Manage.

Sandbox Mode: Always start by checking "Enable Test Mode."10 CrediMax provides a set of test card numbers to verify that the connection is working before you take real money.

Go Live: Once testing is successful, uncheck "Test Mode" and enter your live Production credentials.

### Why choose MPGS over MIGS?

If you are migrating an older site, you might see references to MIGS (Mastercard Internet Gateway Service). MPGS is the newer, more secure replacement. MIGS is being phased out globally, so if you are starting a new project in 2026, you should exclusively use the MPGS version of the plugin.
