Platform Integrations

Genius Checkout ships first-class integrations for the platforms below, plus a documented pattern for anything not on the list. Each plugin/app surface is built on the same public /api/v1 endpoints — there are no platform-specific backend hooks.

WooCommerce

A drop-in WordPress plugin for WooCommerce stores. Supports Block and classic checkout, WooCommerce Subscriptions, refunds from the WP admin, and detailed private order notes.

→ WooCommerce Plugin guide

HighLevel (Lead Connector)

A Custom Payment Provider with full OAuth install flow. Once installed by a HighLevel agency or location, it appears as a payment option in funnels, order forms, and subscription products. Handles tokenization, subscriptions (we run the schedule, not HighLevel), and refunds from inside HighLevel.

Install entry point: https://app.geniuscheckout.com/lc/install

Give (WordPress donations)

WordPress plugin for the Give donation form builder. Uses only public /api/v1/* endpoints — no Give-specific surface on the platform. Supports refunds, tokenized recurring donations, and 4-locale buyer messaging.

→ Give Plugin guide

PrestaShop 8.x

Drop-in module that adds Genius Checkout as a payment option at PrestaShop checkout. Hosted-redirect flow with HMAC-verified webhook receiver.

→ PrestaShop Plugin guide

OpenCart 4.x

Payment extension for OpenCart 4. Hosted-redirect, refund propagation on payment.refunded, multi-language admin.

→ OpenCart Plugin guide

Magento 2

Payment-method module for Magento 2 — admin config UI, Knockout frontend renderer, saved-card picker (via the server-side proxy), refund through Magento's credit-memo flow.

→ Magento 2 Plugin guide

Wix (Velo)

Velo Service Plugin SDK starter — drop into a Wix Studio merchant's Velo backend without going through Wix App Market review. Hosted-redirect + refund.

→ Wix Plugin guide

Odoo

Native Odoo payment provider supporting hosted card checkout, refunds (full + partial), saved cards / tokenization, Odoo Subscriptions integration, and HMAC-verified webhooks. Versions 17 / 18 / 19, with a 16 backport.

→ Odoo Plugin guide

Zapier & Make.com

REST-hook subscribe / unsubscribe / sample-payments endpoints back the official Zapier app and the Make.com module. The same surface is callable from any system that supports the REST-hook pattern.

→ Zapier / Make.com guide

Any Other Platform

The standard pattern for integrating any custom or third-party platform:

1. Create a checkout session with order details and customer info.
2. Redirect the customer to checkout_url.
3. Verify on return via GET /checkout-sessions/{id} — never trust the redirect URL.
4. Listen for webhooks as the authoritative confirmation.
5. Store token_id if you need to charge again later (renewals, top-ups).
6. Refund via POST /payments/{transaction_id}/refund.

Anywhere you can make an outbound HTTPS call and expose a webhook endpoint, you can integrate Genius Checkout.
