# Server2Server

{% hint style="info" %}

#### PCI DSS Compliance

A direct API integration places the responsibility of handling cardholder data on your servers. Therefore, achieving and maintaining compliance with the **Payment Card Industry Data Security Standard (PCI DSS)** is mandatory. This ensures that sensitive payment information is protected according to the highest industry security standards.

For detailed requirements, please consult the official PCI Security Standards Council documentation.

## Design your payment experience

Our Server-to-Server API empowers you to process card payments directly on your website or application. This solution provides maximum control, allowing you to design a fully integrated and seamless checkout experience that lives entirely within your platform.

## Core advantages

A direct API integration offers several key benefits:

* **Total brand control:** Craft a payment journey that perfectly mirrors your brand. You control the entire user experience, ensuring a consistent and personalized interaction from start to finish.
* **Enhanced customer trust:** Maintain customer confidence by keeping users on your site throughout the payment process. A familiar environment assures customers that their sensitive data is being handled securely by a brand they trust.
* **Optimized for conversion:** Take full ownership of your checkout flow. By removing redirects and controlling every step, you can minimize friction and optimize your way to higher conversion rates.
