# Introduction

> Programmatic access to data and UI workflows

DUI API gives developers a simple, RESTful interface to query resources, trigger UI workflows, and build integrations — all over standard HTTP.

DUI API is a developer-first REST API that gives you programmatic access to your data and UI-driven workflows. Whether you're building internal tools, automating repetitive tasks, or integrating DUI into your existing stack, DUI API provides the endpoints, authentication, and documentation you need to ship fast. It's designed for developers who want a clean interface, predictable responses, and the flexibility to build whatever they need.
