## 🔐 AUTHENTICATION

### JWT Token Authentication
The API uses JSON Web Tokens (JWT) for secure authentication. All API endpoints (except authentication endpoints) require a valid JWT token.

#### 1. Login and Obtain Token
```bash
curl -X POST http://yoursite.com/wp-json/care/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{
    "username": "admin",
    "password": "password"
  }'
```

#### Response Format
```json
{
  "success": true,
  "data": {
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
    "expires_in": 3600,
    "user": {
      "id": 1,
      "user_type": "administrator",
      "full_name": "Administrator",
      "email": "admin@example.com",
      "clinic_id": null
    }
  }
}
```

#### 2. Use Token in Requests
Include the JWT token in the Authorization header for all API calls:

```bash
curl -X GET http://yoursite.com/wp-json/care/v1/patients \
  -H "Authorization: Bearer YOUR_JWT_TOKEN_HERE" \
  -H "Content-Type: application/json"
```

#### 3. Refresh Token
When your token expires, use the refresh token to obtain a new one:

```bash
curl -X POST http://yoursite.com/wp-json/care/v1/auth/refresh \
  -H "Content-Type: application/json" \
  -d '{"refresh_token": "YOUR_REFRESH_TOKEN_HERE"}'
```

### Role-Based Access Control
The API supports different user roles with specific permissions:

| Role | Permissions |
|------|------------|
| **Administrator** | Full access to all endpoints and data |
| **Clinic Admin** | Manage clinic data, doctors, patients, appointments |
| **Doctor** | Access own patients, appointments, create prescriptions |
| **Patient** | View own medical data, book appointments |
| **Receptionist** | Manage appointments, basic patient information |

```

### Monitorização em Tempo Real
```bash
# Métricas de performance
curl -X GET http://yoursite.com/wp-json/kivicare/v1/system/performance \
  -H "Authorization: Bearer TOKEN"

# Response time, memory usage, query count, cache hits/misses
```

## 🔒 SEGURANÇA & COMPLIANCE

### Funcionalidades de Segurança
- **🔐 JWT Authentication** - Tokens seguros com expiração
- **🏥 Clinic Isolation** - Isolamento rigoroso entre clínicas  
- **👤 Role-based Access** - Controle de acesso por função
- **🛡️ Input Validation** - Validação completa de inputs
- **📝 Audit Logging** - Logs detalhados de segurança
- **🚫 Rate Limiting** - Proteção contra abuse

### Matriz de Permissões
```php
'administrator' => ['all_operations'],
'doctor' => ['read_own_patients', 'create_encounters', 'prescriptions'],
'patient' => ['read_own_data', 'book_appointments'],
'receptionist' => ['manage_appointments', 'basic_patient_data']
```

## 🔧 TROUBLESHOOTING

### Common Issues

#### Plugin Activation Problems
```bash
# Check if KiviCare base plugin is active
wp plugin list --status=active | grep kivicare

# Check PHP version compatibility
php -v  # Should be 8.1+

# Check WordPress debug logs
tail -f /wp-content/debug.log | grep care-api

# Verify composer dependencies
composer install --no-dev
```

#### API Endpoint 500 Errors
```bash
# Check file permissions
find /wp-content/plugins/kivicare-api -type f -exec chmod 644 {} \;
find /wp-content/plugins/kivicare-api -type d -exec chmod 755 {} \;

# Check memory limit
wp config get WP_MEMORY_LIMIT  # Should be 512M+

# Enable debug mode temporarily
wp config set WP_DEBUG true
wp config set CARE_API_DEBUG true
```

#### JWT Authentication Issues
```bash
# Apache - add to .htaccess
RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.+)$
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# Or add this line:
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
```

For Nginx, add to your server configuration:
```nginx
location ~ \.php$ {
    fastcgi_param HTTP_AUTHORIZATION $http_authorization;
    # ... other fastcgi params
}
```

#### Database Connection Issues
```bash
# Test database connectivity
wp db check

# Verify KiviCare tables exist
wp db query "SHOW TABLES LIKE 'kc_%'"

# Check database permissions
wp db query "SHOW GRANTS FOR CURRENT_USER()"
```

### Performance Optimization

#### Enable Caching
```php
// In wp-config.php
define('CARE_API_CACHE_TTL', 3600); // 1 hour
define('WP_CACHE', true);
```

#### Server Requirements
- **PHP Memory Limit**: 512MB minimum, 1GB recommended
- **Max Execution Time**: 60 seconds minimum
- **Upload Max Size**: 32MB minimum for file uploads
- **Database**: Ensure proper indexing on KiviCare tables

    if (data) {
      options.body = JSON.stringify(data);
    }

    const response = await fetch(url, options);
    return response.json();
  }

        instructions: 'Take with food'
      });

      // 4. Generate bill
      const bill = await this.request('bills', 'POST', {
        patient_id: patientId,
        encounter_id: encounter.data.id,
        clinic_id: clinicId,
        total_amount: 150.00,

    "message": "Patient with ID 999 does not exist",
    "details": {
      "patient_id": 999,
      "clinic_id": 1
    }
  }
}

// Error handling in requests
async function safeApiCall() {
  try {
    const response = await fetch('/wp-json/care/v1/patients/999', {
      headers: { 'Authorization': 'Bearer ' + token }
    });
    
    const result = await response.json();
    
    if (!result.success) {
      console.error('API Error:', result.data.message);
      return null;
    }
    
    return result.data;
  } catch (error) {
    console.error('Network Error:', error);
    return null;
  }
}
```
