Overview

Don’t know which part of the documentation to read?
This section will give a brief overview of integration options for your use case.
E-commerce Solutions
Citcon's e-commerce solutions give merchants a few ways to accept payments. Ready-made plugins cover major platforms like Shopify, WooCommerce, and Magento, letting merchants add payment acceptance with little to no custom development. Pay-by-Link (also known as Invoice 2.0) covers simpler cases like phone orders or emailed invoices via a shareable payment link. Merchants wanting full control over the checkout experience can instead integrate directly against the Universal API (UPI) or the Classic Endpoints, which requires merchant-side development work.

Across all paths, merchants get the same underlying capabilities: global payment method coverage, built-in risk tools (Sift, 3D Secure), and a dashboard for transactions, settlements, and disputes.
Universal Payment interface (UPI)-API
Citcon's Universal Payment Interface (UPI) is a single, unified API that lets merchants accept dozens of payment methods around the world through one integration, rather than building and maintaining separate connections for cards, wallets, bank transfers, and buy-now-pay-later options in every market they operate in.
Features
Citcon's Universal Payment Interface (UPI) gives merchants a single API to accept more than 100 payment methods across the globe — cards, digital wallets, buy-now-pay-later, bank/cash-based rails, and crypto — so expanding into a new market or adding a new payment method is mostly a configuration change, not a new integration project.
  • One API for 100+ payment methods worldwide — cards, wallets, BNPL, bank transfers, and regional rails
  • Layered fraud and security tools: 3D Secure, CVV/AVS checks, and payment method verification
  • Built-in tokenization and vaulting for stored credentials and recurring/subscription payments
  • Mobile iOS and  Android SDKs support
CHOP API (Legacy)
Citcon CHOP solution fits for merchants looking for an easy flexible solution for their web and mobile browser payment experience. CHOP offers forms that are mobile-optimized and designed to reduce friction in your customer experience. You can use CHOP’s payment form template technology to create a brand-consistent, seamless checkout experience for your shoppers.
