# API Overview

> Explore the Collate API for programmatic access to metadata, integrations, automation workflows, and management of data assets, discovery, governance, and quality.

# Overview

The Collate API provides programmatic access to all metadata in your data catalog. Use it to build integrations, automate workflows, and manage your data assets at scale through REST APIs or native SDKs for Python, Java, and Go.

All API interactions happen over HTTPS using JSON. Authenticate every request with a JWT Bearer token. Admins obtain bot tokens under **Settings** > **Bots**. For a personal token, open **Profile** > **Access Tokens**.

For more information about token types and security best practices, see [Authentication](/ai-2-0/developer-guide/api-reference/authentication).
