# Which Problems Are Solved

The `/apis/introduction` page did not give developers clear guidance on
which API version to use. v1 and v2 were presented as equal choices, the
v2 resource list was incomplete, the API path prefix block was
misleading, and several links used inconsistent relative paths.

- No clear recommendation to use v2 for new integrations
- v1 APIs not labelled as legacy
- "APIs v2" section only listed 3 of 15 available v2 services
- Path prefix block only listed 5 of 15 v2 gRPC service paths, with no
distinction between REST and gRPC/Connect access patterns
- `/ui/` path listed as a single entry — the Management Console
(`/ui/console/`) and hosted Login UI (`/ui/login/`) were not
distinguished
- Relative links (`../guides/...`, `./assets/assets`) inconsistent with
the rest of the page
- Auth disclaimer paragraph was confusing; "Custom" section heading was
unclear

# How the Problems Are Solved

- **v2-first framing**: Added a clear directive — "Use the v2 APIs for
all new integrations" — and renamed the old section to "Legacy v1 APIs"
- **Complete v2 resource list**: All 15 v2 services now listed with
one-line descriptions (User, Session, Org, Instance, Project,
Application, IDP, Group, Settings, Feature, Authorization, Action,
WebKey, OIDC, SAML)
- **Full path prefix list**: All 15 v2 gRPC service paths listed; split
into `# REST (HTTP/JSON transcoding): /v2/` and `# gRPC + Connect
protocol (binary or JSON via connectRPC):`
- **`/ui/` paths clarified**: Split into `/ui/console/` (Management
Console) and `/ui/login/` (Hosted Login UI) with inline comments
- **Fixed relative links**: `../guides/...` → `/guides/...`;
`./assets/assets` → `/apis/assets/assets`
- **Section copy improvements**: Auth disclaimer removed; "Custom"
renamed to "Session-based and custom login" with clear bullet list; v1
API card descriptions updated with v2 pointers; Assets card, System card
title fix
- **Client libraries section**: Replaced noisy "API definitions" section
with cleaner "Client libraries & schemas"

@zitadel/docs

Documentation for Zitadel, built with Fumadocs and Next.js.

Getting Started

Ensure you have followed the root quick start to set up dependencies.

Local Development

Start the development server:

pnpm nx run @zitadel/docs:dev

The site will be available at http://localhost:3000.

Scripts

Key scripts for documentation workflows:

Script Description
dev Starts the development server.
build Builds the production application.
fetch:remote-content Fetches remote tags and referenced content.
generate Runs all generation steps (fetch:remote-content, generate:proto-docs, generate:api-reference, generate:index-pages).
check:links Validates content integrity (broken links, missing frontmatter, schema errors).
check-types Validates typescript types.
test Runs all validation steps (check-types, check:links).
lint checks for code style and syntax errors (ESLint).
clean Cleans the build output and generated files.

Validation

  • Code Quality: Run pnpm lint to check for syntax and style issues in JS/TS/MDX files.
  • Content Integrity: Run pnpm check:links to validate content structure, including:
    • Broken internal links
    • Missing required front-matter (e.g., title)
    • Image references

Build Process

The docs build process automatically handling the following steps via generate:

  1. Downloads required protoc plugins.
  2. Generates gRPC documentation from proto files.
  3. Generates API documentation from OpenAPI specs.
  4. Generates index files for directory structures.

Style Guide

  • Variables: Use environment variables in code snippets where possible.
  • Embedded Content: Use _filename.mdx for content embedded in other pages (not indexed individually).
  • Code Embedding: Use the file property in code blocks to embed code from the repo.
  • Voice: Use active voice and sentence case for titles.

Refer to the Google Developer Style Guide for general guidelines.

Adding Content

All documentation content is located in the content directory. Note that the system strictly accepts only .mdx files.

To add a new page:

  1. Create a .mdx file in the appropriate subdirectory of content.
  2. Register the new page in the sidebar settings at lib/sidebar-data.ts to make it accessible in the navigation.

Pull Requests

Use docs(<scope>): <short summary> for PR titles. Pass quality checks before submitting:

pnpm nx run @zitadel/docs:build
pnpm nx run @zitadel/docs:check:links

You can also run specific steps individually:

  • pnpm fetch:remote-content
  • pnpm generate:api-reference
