For Cloud Server and Dedicated Server managed in the Cloud Panel

The Cloud Server API is a programming interface that allows easy access to all functions of the Cloud Server. This programming interface follows the RESTful API design. REST (Representational State Transfer) is an architectural style for the realization of web services. This API uses standard HTTP methods to perform queries and operations, and it allows you to integrate the functions of the Cloud Server into any applications and services.

You can access the API using the following URL:

https://cloudpanel-api.ionos.com/v1

You can also send your HTTP requests to this URL.
