API Reference

Welcome to the Zendesk API reference docs. Whether you're an experienced developer and Zendesk user or just starting out, this is where you'll find the documentation you need.

Most of our APIs are organized by product capabilities. You'll find APIs for ticketing, help center, live chat, voice, sales CRM as well as some features that span capabilities, such as omnichannel routing and custom data. For each API, you'll find information about who can authenticate requests, detailed descriptions of endpoints, example requests, and other essential information to help you unlock the full potential of Zendesk.
