# Introduction

Our REST APIs allow applications to integrate with Pagero Online.

The APIs are based on REST principles with resources represented in JSON format.

The API consists of several individual APIs that handle different parts of the Pagero Online platform. These APIs are managed separately but they all follow the same general principles and guidelines, making it easy to work with them in a consistent way.

Start with the API guidelines for more detailed information about our API.

To access the API, an authentication token is required. Please see the API authentication section for more info on how to obtain this.

Then, move on to the API reference section which provides the full documentation for each of the APIs.
