<h2>About Adyen API</h2>

The Adyen Payment API is a comprehensive set of endpoints designed to facilitate various payment operations on the Adyen payments platform. This API enables businesses to initiate, settle, and modify payments, supporting a wide range of payment methods including card payments (with features like One-Click and 3D Secure), bank transfers, and e-wallets.
Key features of the Adyen API include: 
<ol>
 <li>Versatile payment processing: Handles authorizations, captures, cancellations, and refunds.</li>
 <li>Multi-method support: Accommodates various payment methods to cater to diverse customer preferences.</li>
 <li>Security features: Implements 3D Secure and 3D Secure 2 for enhanced transaction security.</li>
 <li>Flexible operations: Allows for partial captures, multiple refunds, and authorization adjustments.</li>
 <li>Custom references: Supports operations using merchant-defined references for easier reconciliation.</li>
</ol>
The API is designed for what Adyen calls a "Classic integration," providing developers with granular control over the payment flow. It's particularly useful for businesses requiring complex payment scenarios or those looking to build a fully customized payment experience.
