<Eyebrow>API Reference</Eyebrow>
Every endpoint is a first-class, deep-linkable page generated directly from the canonical OpenAPI spec. Per-endpoint code samples in **curl, PowerShell, Python, Node, and Go**.
<StatStrip stats={[
{value: '549', label: 'Endpoints'},
{value: '38', label: 'Resource groups'},
{value: '5', label: 'Languages', hint: 'curl · PowerShell · Python · Node · Go'},
{value: 'v4', label: 'API version', hint: 'Stable, semver-tracked'}
]} />

## Start here

meta: '6 quick recipes'
},

## Common workflows
<CardGrid columns={2} cards={[
{
title: 'Channels',
icon: 'channels',
to: '/api/reference/channels',
description: 'Create, list, archive, and manage channels. Add and remove members, change channel type, set headers and purposes.'
},
{
title: 'Posts',
icon: 'channels',
to: '/api/reference/posts',
description: 'Post, edit, delete, pin, react. Search, fetch threads, retrieve flagged posts.'
},
{
title: 'Users',

},

}

## How it's generated
The canonical source is the OpenAPI specification in `mattermost/mattermost/api/v4/source/` (56 YAML fragments, one per resource). The build pipeline:
```bash
node docs-site/scripts/build-openapi.mjs # bundle 56 fragments → one YAML, 435 paths, 550 ops
npx docusaurus gen-api-docs all # emit ~589 MDX files (one per endpoint + tag pages)
```
When the upstream spec changes, this regenerates automatically. AI never authors API reference content — it's deterministic from the spec.

The legacy ReDoc-based reference at `developers.mattermost.com/api-documentation` is being decommissioned as part of the cutover (see PLAN.md §11.1 step 10).
