BigCommerce

Accept payments with Finix on BigCommerce.

BigCommerce Overview

BigCommerce is a leading open SaaS eCommerce platform trusted by more than 130,000 mid-market and enterprise merchants worldwide. It offers a flexible, headless architecture with built-in tools for storefront management, multi-channel selling, inventory, and promotions — without requiring a full platform replatform. Finix integrates with BigCommerce through the Cybersource payment gateway, enabling merchants to accept payments directly within their BigCommerce checkout.

Finix Requirements

• Finix Live Account
• Active BigCommerce account

Integration

Step 1: Sign up for a Finix Account

To create a Finix account, you can follow our step-by-step guide or sign up directly for a live or sandbox account.

We recommend choosing Direct Merchant as your Customer Type.

Step 2: Create a Cybersource Gateway Integration

Finix supports BigCommerce via our Cybersource Gateway integration. Please note that there is an additional fee for using our Cybersource integration.
