# Introduction

> Introduction to the e-CROSS APIs

e-CROSS APIs are the entry point to the e-CROSS platform. They allow you to manage your catalog (product content, prices and inventory) as well as your orders (order information, fulfillment, tracking, etc.).

The APIs are exposed over HTTPS and use the JSON format for both requests and responses.

## Authentication

All of the e-CROSS APIs are private!

For more information on how to authenticate and obtain a token, please refer to the [Authentication](/api-reference/overview/authentication) section.

## Pagination

e-CROSS APIs use token-based pagination to handle large datasets. Instead of returning all results in a single response, the API returns a token that can be used to retrieve the next page of results.

For more information on how to use pagination, please refer to the [Pagination](/api-reference/overview/pagination) section.
