# Cortina API Overview

The Cortina API documentation provides comprehensive information about the various available endpoints. The API enables a payment gateway (Integrator) to process payments via Nayax systems. This guide will help you understand the API's structure, endpoints, and usage.

## Backward Compatibility

Nayax reserves the right, at its sole discretion, to modify its APIs from time to time, for purposes including but not limited to the introduction of new functionality, enhanced data reporting, or regulatory compliance. Nayax will use commercially reasonable efforts to provide the Customer with no less than **fourteen (14) calendar days' advance written notice**.

Notwithstanding the foregoing, Nayax shall use reasonable efforts to maintain existing fields in a manner that does not break backward compatibility.

The above notice period shall not apply to modifications required to remediate a security vulnerability, comply with a legal or regulatory obligation, or address an urgent operational issue.
