# Introduction

## What is the Emidat API?

The Emidat API is designed for manufacturers integrating from ERP systems or any
automated workflow. It lets you create product instances and supplier products
programmatically.

## Preview endpoints

Some endpoints carry a <span className="badge badge-warn">Preview</span> tag in the navigation. They are
live and supported, but their contract is not frozen yet: request and response
shapes, field names, and error codes may still change in ways that break existing
integrations, and we may do so without a deprecation period.
