# Story 3.6: Documentation OpenAPI (Swagger + ReDoc)
Status: done
<!-- Note: Validation is optional. Run validate-create-story for quality check before dev-story. -->
## Story
En tant que **Développeur/API User**,
Je veux **avoir une documentation API interactive et complète**,
de sorte que **je puisse comprendre et tester tous les endpoints de l'API facilement**.
## Acceptance Criteria
1. **Swagger UI Accessible**: GET `/docs` affiche Swagger UI avec tous les endpoints. (FR35, NFR18)
2. **ReDoc Accessible**: GET `/redoc` affiche ReDoc avec documentation claire et lisible.
3. **Schémas Complets**: Tous les request/response schemas sont documentés avec types et descriptions.
4. **Authentification Documentée**: Méthodes JWT et API Key sont documentées dans OpenAPI avec exemples.
5. **Codes Erreur Documentés**: Tous les codes d'erreur sont listés avec exemples JSON.
6. **Version API**: La version (v1) est clairement visible dans la documentation.
7. **Try It Out**: Swagger UI permet de tester les endpoints directement depuis l'interface.

## Dev Notes
### État Actuel de la Documentation
**Documentation EXISTANTE** (FastAPI génère automatiquement):
- `/docs` - Swagger UI (par défaut) ✅
- `/redoc` - ReDoc (par défaut) ✅
- `/openapi.json` - Spec OpenAPI brute ✅
**CE QUI MANQUE**:
- ❌ Descriptions complètes pour tous les endpoints
- ❌ Exemples de request/response
- ❌ Documentation des codes d'erreur
- ❌ Documentation des schémas d'authentification
- ❌ Modèles Pydantic pour toutes les requests/responses
- ❌ Exemples concrets pour tester depuis Swagger UI
### Architecture OpenAPI FastAPI
**FastAPI génère automatiquement OpenAPI 3.0**, mais nécessite configuration:
```python
# main.py - Configuration de base
from fastapi import FastAPI
app = FastAPI(
title="Office Translator API",
version="1.0.0",
description="API de traduction de documents Office (Excel, Word, PowerPoint)",
docs_url="/docs", # Swagger UI
redoc_url="/redoc", # ReDoc
openapi_url="/openapi.json" # OpenAPI spec
)
```
**Configuration AVANCÉE recommandée**:
```python
# main.py
from fastapi import FastAPI
from fastapi.openapi.utils import get_openapi
def custom_openapi():
if app.openapi_schema:
return app.openapi_schema
openapi_schema = get_openapi(
title="Office Translator API",
version="1.0.0",
description="""
API de traduction de documents Office avec préservation du format.
## Authentification
L'API supporte deux méthodes d'authentification:
### 1. JWT (Web Dashboard)
- Obtenez un token via `/api/v1/auth/login`
- Utilisez le header: `Authorization: Bearer <token>`
- Token expire en 15 minutes (access) ou 7 jours (refresh)
### 2. API Key (Automation)
- Générez une clé via `/api/v1/api-keys` (Pro users only)
- Utilisez le header: `X-API-Key: sk_live_xxx`
- Clé statique, révocable
## Endpoints Principaux
- **Translation**: POST /api/v1/translate
- **Status**: GET /api/v1/translations/{id}
- **Download**: GET /api/v1/download/{id}
- **Languages**: GET /api/v1/languages
## Codes d'Erreur
Tous les codes d'erreur suivent le format:
```json
{
"error": "ERROR_CODE",
"message": "Description lisible",
"details": {...}
}
```
Codes courants: `INVALID_FORMAT`, `QUOTA_EXCEEDED`, `UNAUTHORIZED`, `PROVIDER_ERROR`
""",
routes=app.routes,
)
# Configuration des security schemes
openapi_schema["components"]["securitySchemes"] = {
"JWT": {
"type": "http",
"scheme": "bearer",
"bearerFormat": "JWT",
"description": "JWT token from /api/v1/auth/login"
},
"APIKey": {
"type": "apiKey",

## Intelligence des Stories Précédentes (Epic 3)
### Story 3.1 (API Key Generation) - Enseignements
1. **Routeur api_key_routes.py** utilise `prefix="/api/v1/api-keys"` ✅
2. **Pattern de réponse** `{data: {...}, meta: {...}}` établi
3. **Tests complets** avec fixtures dans `tests/conftest.py`
### Story 3.2 (API Key Revocation User) - Enseignements
1. **Soft delete** avec `is_active=False`
2. **Fonction `get_user_by_api_key`** dans `services/auth_service.py`
3. **Format d'erreur structuré** `{error, message, details?}`
### Story 3.3 (Admin API Key Revocation) - Enseignements
1. **Routes admin dans main.py** - à migrer vers `routes/admin_routes.py`
2. **Dépendance `require_admin`** pour l'authentification admin
3. **Audit logging** avec `logger.info()`
### Story 3.4 (API Auth X-API-Key) - Enseignements
1. **Coexistence JWT + API Key** dans `get_authenticated_user`
2. **Middleware d'auth** dans `routes/translate_routes.py`
3. **Priorité API key sur JWT** si les deux présents
### Story 3.5 (API Versioning) - Enseignements
1. **Tous les endpoints** sont maintenant sous `/api/v1/` ✅
2. **Exceptions documentées**: `/health`, `/ready`, `/docs`, `/redoc` accessibles sans préfixe
3. **Routeur principal** `routes/api_v1_router.py` composé de sous-routeurs
4. **Configuration FastAPI** avec `title`, `version`, `description` dans main.py
## Intelligence Git (Commits Récents)
Derniers commits pertinents:
- `3d37ce4`: PostgreSQL database infrastructure
- `550f351`: Database migrations avec Alembic
- `c4d6cae`: Security hardening, Redis sessions
**Patterns identifiés**:
- Tests avec `pytest` dans `tests/`
- Fixtures dans `tests/conftest.py`
- Configuration via `config.py` et variables d'environnement
## Contexte Métier
### Epic 3: API & Automation (Pro)
Cette story est la **sixième de l'Epic 3** qui permet aux utilisateurs Pro d'automatiser les traductions:
1. ~~API Keys - Génération~~ (Story 3.1 ✅)
2. ~~API Keys - Révocation User~~ (Story 3.2 ✅)
3. ~~API Keys - Révocation Admin~~ (Story 3.3 ✅)
4. ~~Authentification X-API-Key~~ (Story 3.4 ✅)
5. ~~API Versioning~~ (Story 3.5 ✅)
6. **Documentation OpenAPI** (cette story)
7. Webhooks (Stories 3.7-3.8 - backlog)
8. Glossaires (Stories 3.9-3.10 - backlog)
9. Custom Prompts (Stories 3.11-3.12 - backlog)
### Valeur Business
La documentation OpenAPI est critique pour:
- **Adoption**: Thomas (Pro user) peut explorer l'API sans lire de doc externe
- **Testabilité**: Swagger UI permet de tester directement dans le navigateur
- **Intégration**: Les clients peuvent générer du code client depuis la spec OpenAPI
- **Maintenance**: La documentation est toujours à jour (générée depuis le code)
- **Professionalisme**: Standard de l'industrie pour les APIs REST
### Dépendances
- **Stories 3.1-3.5** (prérequis): Tous les endpoints doivent exister et être versionnés ✅
- **Stories futures** (impact): Webhooks, Glossaires, Custom Prompts devront être documentés
## Guardrails Développeur
### ❌ À NE PAS FAIRE
1. **NE PAS** supprimer ou déplacer `/docs`, `/redoc`, `/openapi.json`
2. **NE PAS** utiliser des docstrings vides ou génériques
3. **NE PAS** oublier de documenter les codes d'erreur
4. **NE PAS** créer des modèles Pydantic incomplets (tous les champs doivent avoir des descriptions et exemples)
5. **NE PAS** ignorer les exemples de request/response
6. **NE PAS** oublier de documenter l'authentification (JWT + API Key)
### ✅ À FAIRE
1. **TOUJOURS** ajouter des descriptions complètes dans les endpoints
2. **TOUJOURS** créer des modèles Pydantic pour toutes les requests/responses
3. **TOUJOURS** documenter TOUS les codes d'erreur possibles
4. **TOUJOURS** ajouter des exemples concrets (example parameter dans Field)
5. **TOUJOURS** utiliser le dict `responses={}` pour documenter les erreurs HTTP
6. **CRÉER** un fichier `schemas/errors.py` avec tous les codes d'erreur
7. **CRÉER** un fichier `schemas/` pour organiser les modèles Pydantic
8. **CONFIGURER** `custom_openapi()` dans main.py pour la documentation personnalisée

## Authentification
L'API supporte deux méthodes d'authentification:
### 1. JWT (Web Dashboard & Admin)
Utilisé pour l'interface web et le dashboard admin.
**Obtenir un token:**
```bash
POST /api/v1/auth/login
{
"email": "user@example.com",
"password": "password123"
}
```
**Utiliser le token:**
```
Authorization: Bearer eyJhbGciOiJIUzI1NiIs...
```
**Détails:**
- Access token expire en 15 minutes
- Refresh token expire en 7 jours
- Utilisez `/api/v1/auth/refresh` pour renouveler l'access token
### 2. API Key (Automation)
Utilisé pour l'automatisation et l'intégration (Pro users only).
**Obtenir une clé:**
```bash
POST /api/v1/api-keys
Authorization: Bearer <jwt_token>
```
**Utiliser la clé:**
```
X-API-Key: sk_live_abc123def456...
```
**Détails:**
- Clé statique, pas d'expiration
- Peut être révoquée à tout moment
- Uniquement pour utilisateurs Pro
