# 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.
