The RestroPress Adyen Payment Gateway integrates Adyen’s secure card payment infrastructure directly with your RestroPress online ordering system. It renders Adyen’s secure payment fields on the checkout page, processes the transaction, handles 3D Secure (3DS) authentication redirect flows, and dynamically updates the order status using Adyen’s API responses and webhook notifications.
Key Features
- On-Site Secure Checkout: Renders Adyen’s official secure payment fields inline on your checkout page, keeping customers on your website.
- 3D Secure 2.0 (3DS) Redirects: Full support for 3DS redirect flows to comply with PSD2 and strong customer authentication (SCA) regulations.
- Dynamic Webhook Syncing: Dynamically updates order payment statuses in RestroPress via Adyen webhooks when payments are captured, authorized, or failed.
- Webhook HMAC Signature Verification: Built-in HMAC key validation secures webhook endpoints against unauthorized or spoofed payloads.
- Main Test/Live Toggle: Automatically switches between sandbox and production modes based on the primary RestroPress test mode setting.
Admin Configuration Fields
The extension adds a dedicated settings panel under RestroPress > Settings > Payment Gateways > Adyen containing:
- API Key (Separate fields for Test and Live keys)
- Merchant Account Identifier (Separate fields for Test and Live accounts)
- Client Key (Used to load Adyen secure fields securely on the frontend)
