Payments: Custom Payment Gateway Integration

Your choice of processor shouldn’t depend on which plug-ins your store happens to offer.

No Plug-In for Your Processor

You’ve picked the payment processor you want, and your ecommerce platform has no ready-made way to connect to it. Or you need split payments or another feature the standard plug-in can’t do.

We build the custom connection. We link to your processor’s API, handle tokenization, which swaps card numbers for safe stand-ins, and manage webhooks, the messages that report each payment event. The result is a PCI-compliant setup on any platform.

How We Build the Connection

1

Review the requirements

We look at your platform, your processor and any special needs, such as split payments or recurring billing.

2

Connect the API

Direct calls to the processor’s API, plus tokenization, keep card data off your servers.

3

Handle payment events

Webhooks carry each payment update from the processor back to your platform.

4

Build to PCI-DSS

PCI-DSS rules for secure development shape the work, so your site never touches raw card numbers.

Why Choose System Strats

We’ve consolidated payment infrastructure for a range of businesses. We know the processor options, the costs and the compliance rules, and that knowledge goes into each connection we build.
