Legacy gateway, existing credentials only. Mastercard stopped enrolling new merchants on Simplify Commerce in 2025, so new Simplify accounts are not available. This plugin is for merchants who already hold working Simplify credentials and need their checkout to keep running on Joomla 6.

Keep Taking Simplify Payments on J2Commerce 6

Your Simplify account still works, but the previous plugin does not run on J2Commerce 6. This plugin adds tokenized card entry, sandbox and live modes and order notifications for paid orders.

What the Plugin Does

Tokenized checkout, order event routing, geozone control, surcharges and card icons for light and dark mode.

Card Tokenization
Card details are tokenized in the customer's browser, so your server receives a token, never the card number, expiry or CVV.
Sandbox and Live Modes
Switch between test and live credentials with one setting.
Order Notifications on Every Paid Order
Approved payments go through J2Commerce order management, so confirmation emails send, downloads unlock and the order history records the payment.
Four Card Brands, Light & Dark Icons
Choose which cards you accept: Visa, Mastercard, Discover and American Express. The icons you enable appear at checkout, with a light and a dark version of each.
Geozone and Order Size Gates
Show Simplify only in the regions and order-total range your account covers.
Surcharge Support
Add a named surcharge with a percentage, a flat amount and a tax class, shown as an order line.
Configurable Order Status Mapping
Pick one order status for approved charges and another for declines.
Per-Field Error Messages
Each card field shows its own error message, and the submit button shows progress while the payment processes.
Custom Messages at Every Step
Add messaging when customers select this payment method, above the card form, and on the post-payment screen. Set a custom error message for declined charges. Rename the Place Order button. Link a full Joomla article as the post-payment destination.

Card Data That Never Reaches Your Server

The card form in your checkout turns card details into a short-lived token in the customer's browser before anything is submitted. Your server receives the token, never a raw card number.

Raw card numbers never transit your infrastructure
CVV codes never appear in your server logs or database
Card data is tokenized in the browser, which can reduce your PCI scope
Debug logging masks transaction IDs

What Happens After a Payment Is Approved

Every approved charge goes through J2Commerce order management, so these steps run in order.

Confirmation email sends to the customer
Digital product download links unlock immediately
A descriptive history entry records the payment outcome
Declined charges get their own status in your order queue

Use Cases

The Mid-Migration Merchant

A long-time Simplify merchant moving to J2Commerce 6 installs the plugin, enters their existing API keys and launches on schedule, then changes processors later.
