Custom Payment Gateway Integration

Plugin from our shop or a scoped custom build—WooCommerce, Gravity Forms, EDD, Magento, PrestaShop, and AbanteCart. We integrate; your processor settles funds.

PatSaTECH connects stores and forms to the processors merchants already contract with—without breaking checkout. Since 2011, we have built and maintained payment gateway extensions for WooCommerce, Gravity Forms, Easy Digital Downloads, Magento, PrestaShop, and AbanteCart, plus custom integrations when catalog SKUs are the wrong fit.

We focus on secure transaction flows, clear error handling, and checkout behavior you can test in sandbox before production keys.

Quick answer

Custom payment gateway integration at PatSaTECH means either a maintained plugin from the shop (when your processor and cart match a listed SKU) or a quoted build when APIs, payouts, or carts fall outside the catalog. PatSaTECH provides software and services; your acquirer/processor authorizes and settles funds. Start at the platform hub below; if the processor is missing, use get a quote with sandbox access and flow notes.

Definition: A payment gateway integration connects checkout to your existing merchant account. PatSaTECH builds and supports that software—we do not replace your processor.


What payment gateway integration includes

  • Processor fit: Align checkout model (hosted vs direct), countries, and card products with what your contract actually issued—not a reseller’s generic name.
  • Checkout implementation: Hosted fields, redirects, tokenization, subscriptions/recurring where the SKU and processor support them.
  • Platform fit: WooCommerce, Gravity Forms, EDD, Magento, PrestaShop, AbanteCart, or scoped headless/custom carts.
  • Compliance awareness: Merchant PCI responsibilities, 3-D Secure where required, webhooks/IPNs documented for ops.
  • Testing: Sandbox transactions, failed-payment paths, go-live checklists (WooCommerce integration checklist).
  • Maintenance: Gateway API and platform updates—see site maintenance plans when the store is payment-critical.

When you need a custom integration

Commission bespoke work when:

  • Your gateway has no maintained plugin for your cart in the shop.
  • You need a private or regional acquirer with non-catalog APIs.
  • You operate marketplace, multi-vendor, or split-payout flows.
  • You must align ERP, accounting, or tax engines with payment events.

Deliverables (quoted): discovery notes, documented architecture, staged rollout, test plan, handover for your team.

Key takeaways

  • PatSaTECH has shipped payment gateway integrations since 2011 for major WordPress carts and select Magento/PrestaShop/AbanteCart modules.
  • PatSaTECH does not board merchant accounts or act as payment processor of record.
  • Prefer a catalog SKU when the processor and cart match; use custom integration for marketplaces, headless, or unlisted acquirers.
  • Run HPOS, Blocks, and webhook checklists on staging before production—compatibility is per SKU.
  • Agencies: pair this pillar with for agencies and the agency go-live runbook.

FAQs

How long does a typical integration take?
Depends on gateway documentation, sandbox access, and cart complexity. Catalog plugins configure quickly when the SKU fits; custom builds are quoted after discovery—no invented day counts in copy.

Do you support international and multi-currency setups?
Where the processor supports it, we align display, settlement, and gateway rules with your store configuration.

What about PCI DSS?
Merchants remain responsible for PCI scope. We implement patterns that reduce exposure (hosted fields, redirects, tokens) and document what your checklist should cover.

Can you help if checkout breaks after an update?
Start with troubleshooting runbooks (no payment methods, payment timeout). For site-wide breakage, see bounded repair services on services—gateway scope stays on the integration SKU or SOW.
