Genius CheckoutDeveloper Documentation

Card payments, tokenization, subscriptions, and webhooks. Built for the Caribbean and Latin America.

Hosted Checkout

One POST creates a session and returns a checkout URL. We render the payment page, run 3DS, and redirect the customer back. No PCI scope.

Build a checkout

Every successful payment auto-creates a reusable token. Charge it on any cadence — no card data ever touches your servers.

Charge a saved card

HMAC-SHA256-signed event payloads with retry. The authoritative source for "did this charge?".

Verify webhooks

USD, JMD, TTD, BBD, EUR, GYD out of the box. Tax, line items, and order details flow through to the gateway and the receipt.

Pass order details

Drop-in plugin for WooCommerce. Custom Payment Provider for HighLevel. A documented pattern for any other platform.

Pick a platform

Test API keys, test cards (frictionless and 3DS challenge), test sandbox transactions — verify the full flow before going live.
