# PLANNING STRIPE - DÉVELOPPEUR BACKEND PHP
## API PHP 8.3 - Intégration Stripe Connect + Terminal
### Période : 25/08/2024 - 05/09/2024

---

## 📅 LUNDI 25/08 - Setup et architecture (8h)

### 🌅 Matin (4h)
```bash
# Installation Stripe PHP SDK
cd api
composer require stripe/stripe-php
```

#### ✅ Configuration environnement
- [x] Créer configuration Stripe dans `AppConfig.php` avec clés TEST
- [x] Ajouter variables de configuration :
  ```php
  'stripe' => [
    'public_key_test' => 'pk_test_51QwoVN00pblGEgsXkf8qlXm...',
    'secret_key_test' => 'sk_test_51QwoVN00pblGEgsXnvqi8qf...',
    'webhook_secret_test' => 'whsec_test_...',
    'api_version' => '2024-06-20',
    'application_fee_percent' => 0, // DECISION: 0% commission
    'mode' => 'test'
  ]
  ```
- [x] Créer service `StripeService.php` singleton
- [x] Configurer authentification Session-based API

- Commented out Logger class calls (class not found)

#### **StripeService.php** 
- Added proper Stripe SDK imports (`use Stripe\Account`)
- Fixed `Account::retrieve()` → `$this->stripe->accounts->retrieve()`
- **CRUCIAL**: Added data decryption support:
  ```php
  $nom = !empty($entite['encrypted_name']) ? 
    \ApiService::decryptData($entite['encrypted_name']) : '';
  $email = !empty($entite['encrypted_email']) ? 
    \ApiService::decryptSearchableData($entite['encrypted_email']) : null;
  ```
- Fixed address mapping (adresse1, adresse2 vs adresse)
- **REMOVED commission calculation - set to 0%**

#### **Router.php**
- Commented out excessive debug logging causing nginx 502 errors:
  ```php
  // error_log("Recherche de route pour: méthode=$method, uri=$uri");
  // error_log("Test pattern: $pattern contre uri: $uri");
  ```

#### **AppConfig.php**
- Set `application_fee_percent` to 0 (was 2.5)
- Set `application_fee_minimum` to 0 (was 50)
- **Policy**: 100% of payments go to amicales

### 📊 TESTS ET VALIDATION

#### **Tests Réussis**
1. **POST /api/stripe/accounts** → 200 OK (Compte créé: acct_1S2YfNP63A07c33Y)
2. **GET /api/stripe/accounts/5/status** → 200 OK (charges_enabled: true)
3. **POST /api/stripe/locations** → 200 OK (Location: tml_GLJ21w7KCYX4Wj)
4. **POST /api/stripe/accounts/.../onboarding-link** → 200 OK (Link generated)
5. **Onboarding Stripe** → Completed successfully by user

#### **Erreurs Résolues**
- ❌ 500 "Class App\Controllers\Database not found" → ✅ Fixed
- ❌ 400 "Invalid email address: " → ✅ Fixed (decryption added)
- ❌ 502 "upstream sent too big header" → ✅ Fixed (logs removed)
- ❌ SQL "Column not found: details_submitted" → ✅ Fixed

### 🚀 ARCHITECTURE TECHNIQUE

#### **Services Implémentés**
- **StripeService**: Singleton pour interactions Stripe API
- **StripeController**: Endpoints REST avec gestion sessions
- **StripeWebhookController**: Handler événements webhook
- **ApiService**: Déchiffrement données encrypted fields

#### **Sécurité**
- Validation signatures webhook Stripe
- Authentification session-based pour APIs privées
- Public endpoints: webhook uniquement
- Pas de stockage clés secrètes en base

#### **Base de données**
- Utilisation tables existantes (entites)
- Pas de nouvelles tables créées (pas nécessaire pour V1)
- Champs encrypted_email et encrypted_name supportés
- Déchiffrement automatique avant envoi Stripe

### 🎯 PROCHAINES ÉTAPES API
1. **Tests paiements réels** avec PaymentIntents
2. **Endpoints statistiques** pour dashboard amicales  
3. **Webhooks production** avec clés live
4. **Monitoring et logs** des transactions
5. **Rate limiting** sur endpoints sensibles
