Payment Integrations

Payment Gateway Integration Services

I specialize in merchant account and payment gateway integrations, helping businesses securely
accept credit card and online payments. Below are some of the payment providers and integration
methods I have worked with recently:

PSiGate Payment Gateway

  • HTML Messenger – Easy-to-use hosted payment form integration.
  • REST API – Modern, flexible API integration for real-time transactions.
  • XML API – Legacy but powerful integration for custom payment flows.

NMI (Network Merchants)

  • Collect.js – Secure client-side tokenization for PCI compliance.
  • Collect Checkout – Drop-in checkout experience with minimal setup.
  • QuickClick – Simplified hosted checkout link for fast payments.
  • Query API – Retrieve transaction and batch reporting data.
  • Payment API – Full control for processing payments directly through API calls.

Payroc

  • Hosted Payment Page (HPP) – Secure hosted checkout solution for merchants.

Nuvei

  • Payment Page – Seamless hosted payment page integration.

Plug’n Pay

  • Smart Screen v2 – Advanced checkout system for online merchants.

Whether you need API-based integrations, hosted payment pages, or
secure checkout solutions, I can help streamline your payment processing and ensure
your business is ready to accept payments online with confidence.
