Monkeys Commerce Payment Adyen

MonkeysCommerce Payment: Adyen

Adyen payment integration using the Checkout API v71 and Drop-in UI component. PCI-compliant card input, 250+ local payment methods, and HMAC-signed webhooks.

This is an official payment gateway for MonkeysCommerce. It implements the PaymentGatewayInterface plugin system — providing createPayment, capture, refund, and handleWebhook methods.

Features

• Adyen Drop-in Component: PCI-compliant, conversion-optimized checkout UI that adapts to the customer's location and device.

• 3D Secure 2: Native 3DS2 challenge flow for Strong Customer Authentication (SCA) compliance.
• HMAC-Signed Webhooks: Cryptographically verified asynchronous status updates for captures, refunds, and disputes.
