## Authentication

All Super Admin endpoints require JWT authentication with super-admin privileges.

```http
Authorization: Bearer <jwt_token>
```

### Getting Authentication Token
1. Login through the authentication endpoint:
   ```http
   POST /api/v1/auth/login
   Content-Type: application/json

   {
     "email": "admin@bitcrate.co.uk",
     "password": "your_password"
   }
   ```

2. Use the returned JWT token in all subsequent requests

## Rate Limits

API calls are rate limited to ensure system stability:
- **Admin endpoints:** 200 requests per minute
- **Analytics endpoints:** 100 requests per minute

Rate limit headers are included in all responses:
- `X-RateLimit-Limit`: Maximum requests allowed
- `X-RateLimit-Remaining`: Remaining requests in current window

### Pagination
All list endpoints support pagination:

```

Response includes pagination metadata:
```json
{
  "success": true,
  "data": {
    "companies": [...],
    "pagination": {
      "page": 1,
      "limit": 25,
      "total": 100,
      "pages": 4
    }
  }
}
```

### Filtering
Most endpoints support filtering parameters:
```http
GET /api/v1/super-admin/licenses?company_id=123&status=active&expires_soon=true
```

### Sorting
Results can be sorted by supported fields:
```http
GET /api/v1/super-admin/companies?sort_by=created_at&sort_order=desc
```

### Search
Text search is available on relevant endpoints:
```http
GET /api/v1/super-admin/users?search=john@example.com
```

## Error Handling

All endpoints return consistent error responses:

### Success Response
```json
{
  "success": true,
  "data": {
    // Response data
  }
}
```

### Error Response
```json
{
  "success": false,
  "error": "Error message describing what went wrong"
}
```

### HTTP Status Codes
- `200` - Success
- `201` - Created
- `400` - Bad Request (invalid parameters)
- `401` - Unauthorized (invalid/missing token)
- `403` - Forbidden (insufficient permissions)
- `404` - Not Found
- `409` - Conflict (resource already exists)
- `429` - Rate Limit Exceeded
- `500` - Internal Server Error

## Usage Examples

### Get All Companies
```bash
curl -X GET "https://license.bitcrate.co.uk/api/v1/super-admin/companies" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json"
```

### Create a New License
```bash
curl -X POST "https://license.bitcrate.co.uk/api/v1/super-admin/licenses" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "user@company.com",
    "product_id": "550e8400-e29b-41d4-a716-446655440002",

    "expires_at": "2024-12-31T23:59:59Z"
  }'
```

```bash
curl -X GET "https://license.bitcrate.co.uk/api/v1/super-admin/api-keys?company_id=550e8400-e29b-41d4-a716-446655440000&status=active" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json"
```

## Security Considerations

### Authorization
- All endpoints require super-admin role
- JWT token must be valid and not expired
- Session-based authentication with secure tokens

### Rate Limiting
- Comprehensive rate limiting across all endpoints
- Per-IP and per-user rate limiting
- Configurable limits based on subscription tiers

### Audit Logging
- All super-admin actions are logged
- Complete audit trail for compliance
- Security event monitoring and alerting

### Data Protection
- Sensitive data encryption at rest and in transit
- PII protection with access controls
- GDPR compliance for user data handling
