BigCommerce

Last updated: October 19, 2026

Overview

Enhance your BigCommerce store with our payment plugin, offering secure, seamless, and efficient payment processing solutions.

Please note - Full functionality is tested in  test environment (UAT) and production functional testing is pending. 

Our BigCommerce payment extension helps you launch or expand your business rapidly. If you are launching your business first time on BigCommerce, we can help you to quickly roll out through our configuration capabilities. If you are already on BigCommerce and thinking of expansion, we offer a wide variety of secure local and global payment options.

Our BigCommerce extension which is built on Payments Orchestration Platform delivers a competitive advantage over payment gateways including payment processing optimization and advanced analytics through a single integration. We help you manage payments across multiple P2Ps, acquirers and banks across all channels — online, mobile or recurring — using a strategic, streamlined approach.

Compatibility

Our plugin supports following versions:

  • Node 18
  • Remix 2.0.1
  • React 18.2
  • Prisma 5.5

Important

It is strongly recommended that the plugin installation is first completed and validated in a non‑production environment (for example, a QA or staging environment) before proceeding with installation in production.

This plugin is designed to work with the out‑of‑the‑box (OOTB) native BigCommerce checkout.

If your store uses a custom checkout implementation or heavily modified checkout flow, additional customization by the merchant or their implementation partner (agency/integrator) may be required to ensure compatibility with the plugin.

Webhook configuration

The webhooks are HTTP-based callbacks that notify your plugin platform of all the events you subscribed for on an entity. Instead of constantly polling for updates, a webhook is set up once and only sends data when a specific event occurs. The events can be about tokens, payments, payment schedules, risks, or any transaction state updates related to payments or transactions connected to a payment, it is necessary to configure webhooks for seamless communication and transaction updates.
