WordPress: Custom Payment Gateway Integration

When no plugin connects your store to the processor you need, we write the connection ourselves.

When No Plugin Exists

You’ve picked a payment processor, or your industry has picked one for you, and no WordPress plugin supports it. Maybe you bill in a way the standard checkout can’t handle, such as split payments or marketplace payouts.

We build custom payment connections for WooCommerce and WordPress. That can mean a specialized processor, a subscription billing system or a payment tool made for your industry. Tokenization, which swaps card numbers for a safe stand-in, keeps sensitive data off your servers.

What The Integration Includes

A custom connection to your processor’s API, whichever processor you use

Build practices that follow PCI rules for handling card data

Support for specialized billing, such as split payments or marketplace payouts

Tokenization and secure handling of payment data

From Processor To Checkout

1

Map Requirements

First we study your processor’s API and your billing model, including any split payments, payouts or regional rules.

2

Build Connection

The integration uses tokenization and direct API calls, so raw card data never sits on your site.

3

Test In Sandbox

Test cards run through successful payments, declines, refunds, partial captures and errors in a safe sandbox environment.

4

Go Live

Once every scenario passes, we switch your site over to live payments.

Why Choose System Strats

We’ve built and optimized WordPress sites for businesses of all sizes. We know how WordPress is put together and how it connects to the rest of a business, so a custom gateway fits the store you already run.
