# contentful-api

A reference skill for the Contentful REST API: content management, delivery, preview, images and GraphQL. Every example is curl, so it stays language-agnostic.

## What it does

The skill is split by API. Content Management API handles creating and updating entries, content types, assets and environments. Content Delivery API reads published content only. Preview API serves drafts through the same endpoints with a different host and token. Images API does on-the-fly transformations through URL parameters, and GraphQL gets its own section.

Inside are reference files: authentication with token types and US/EU base URLs, plus HTTP conventions for version locking, rate limits, pagination and errors. CMA has separate files for entries, content types, assets and environments. CDA covers filters and search operators, the include parameter, locales and incremental sync. A quick reference holds ready curl commands for creating a draft entry and fetching entries.

You need Contentful tokens to use it: a CMA token for writes, a CDA token for reads. Images API needs no authentication. Publishing an entry is a separate request with the `X-Contentful-Version` header, so a draft will not go live on its own.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add contentful/skills --skill contentful-api -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/contentful-api/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/contentful-api/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add contentful/skills --skill contentful-api -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/contentful-api/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add contentful/skills --skill contentful-api -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/contentful-api/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install contentful/skills contentful-api
```

2. **Manually: put the files in place**
- File: `.github/skills/contentful-api/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add contentful/skills --skill contentful-api -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/contentful/skills --path skills/contentful-api
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/contentful-api/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add contentful/skills --skill contentful-api -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/contentful/skills/tree/HEAD/skills/contentful-api/SKILL.md

## When to use it
- create a draft entry and publish it through CMA
- fetch published entries by content type through CDA
- set up locales and fallback chains for multilingual content
- run incremental content sync
- transform images with URL parameters and no auth

## Example prompts
- Show me how to create a draft blogPost entry via CMA and then publish it
- How do I fetch all entries with content_type=blogPost via CDA and resolve links with include?
- Explain how sync works for incremental content synchronization

# Contentful REST API Guide

Language-agnostic guide for Contentful APIs using HTTP/curl.

## Shared References

- **[Authentication](references/authentication.md)** — Token types, auth headers, API base URLs (US/EU)
- **[HTTP Conventions](references/http-conventions.md)** — Version locking, rate limits, pagination, errors, locale structure

## Content Management API (CMA)

Read/write API for managing content, content types, assets, and environments.

**Start here**: [references/content-management/overview.md](references/content-management/overview.md)

- [**entries.md**](references/content-management/entries.md) — CRUD, publish/unpublish, versioning, query parameters
- [**content-types.md**](references/content-management/content-types.md) — Define/update content models, field types, validations
- [**assets.md**](references/content-management/assets.md) — Upload, process, publish media files
- [**environments.md**](references/content-management/environments.md) — Create, clone, manage environments and aliases

## Content Delivery API (CDA)

Read-only API for fetching published content.

**Start here**: [references/content-delivery/overview.md](references/content-delivery/overview.md)

- [**querying.md**](references/content-delivery/querying.md) — Filters, search operators, pagination, ordering
- [**includes-links.md**](references/content-delivery/includes-links.md) — Include parameter, link resolution
- [**localization.md**](references/content-delivery/localization.md) — Locale parameter, fallback chains
- [**sync.md**](references/content-delivery/sync.md) — Incremental content synchronization

## Content Preview API

Draft + published content via same CDA endpoints, different host/token.

**Reference**: [references/content-preview/overview.md](references/content-preview/overview.md)

## Images API

On-the-fly image transformations via URL parameters. No authentication needed.

**Reference**: [references/images/overview.md](references/images/overview.md)

## GraphQL API

Query content via GraphQL with CDA tokens.

**Reference**: [references/graphql/overview.md](references/graphql/overview.md)

## Quick Reference

```bash
# CMA: Create a draft entry
curl -X POST https://api.contentful.com/spaces/{space_id}/environments/{env_id}/entries \
  -H "Authorization: Bearer {cma_token}" \
  -H "Content-Type: application/vnd.contentful.management.v1+json" \
