## API Endpoints Summary

### Public Endpoints (No Auth Required)
```
GET    /api/users                      - List all users
GET    /api/users/{id}                 - Get user by ID
GET    /api/users/email/{email}        - Get user by email
```

### Protected Endpoints (Auth Required)
```
POST   /api/users                      - Create new user
PUT    /api/users/{id}                 - Update user
DELETE /api/users/{id}                 - Soft delete user
GET    /api/users/trashed/all          - List trashed users
POST   /api/users/{id}/restore         - Restore deleted user
DELETE /api/users/{id}/force           - Force delete user (permanent)
```

## Quick Start Examples

### Create User
```bash
curl -X POST http://localhost:8000/api/users \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "John Doe",
    "email": "john@example.com",
    "password": "SecurePass123"
  }'
```

### Update User
```bash
curl -X PUT http://localhost:8000/api/users/1 \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "John Smith"}'
```

### Soft Delete User
```bash
curl -X DELETE http://localhost:8000/api/users/1 \
  -H "Authorization: Bearer YOUR_TOKEN"
```

### Restore User
```bash
curl -X POST http://localhost:8000/api/users/1/restore \
  -H "Authorization: Bearer YOUR_TOKEN"
```

## Validation Rules

### Create User
- `name`: required, string, max 255 characters
- `email`: required, valid email, unique, max 255 characters
- `password`: required, string, minimum 8 characters

### Update User
- `name`: optional, string, max 255 characters
- `email`: optional, valid email, unique (except current user), max 255 characters
- `password`: optional, string, minimum 8 characters

## Service Layer Methods

```php
UserService::listAll()                    // Get all users
UserService::findById(int $id)            // Find by ID
UserService::findByEmail(string $email)   // Find by email
UserService::create(array $data)          // Create new user
UserService::update(int $id, array $data) // Update user
UserService::delete(int $id)              // Soft delete
UserService::listTrashed()                // Get deleted users
UserService::restore(int $id)             // Restore user
UserService::forceDelete(int $id)         // Permanent delete
```

## Integration Points

### Works With
- **Auth Module** (`AuthService`) - Login/logout functionality
- **Clients Module** - `added_by` and `updated_by` tracking
- **Sectors Module** - `added_by` and `updated_by` tracking
- **Projects Module** - User relationship tracking
- **Sections Module** - User relationship tracking
- **Laravel Sanctum** - API token authentication

## Database Fields

```
id               - Primary key
name             - User's full name
email            - Unique email address
email_verified_at - Email verification timestamp (optional)
password         - Hashed password (bcrypt)
remember_token   - Remember me token
deleted_at       - Soft delete timestamp
created_at       - Creation timestamp
updated_at       - Last update timestamp
```

## Best Practices

1. **Always use UserService** - Don't bypass the service layer
2. **Passwords are auto-hashed** - Service handles hashing automatically
3. **Check for null returns** - Service methods return null if user not found
4. **Use soft delete first** - Only force delete when absolutely necessary
5. **Validate email uniqueness** - Always validate before create/update
6. **Tokens are auto-revoked** - On user deletion, tokens are cleaned up

## Testing the Module

Use the provided examples in `API_EXAMPLES.http` (examples 36-48) with VS Code REST Client extension, or use tools like:
- Postman
- Insomnia
- cURL
- PHPUnit tests

## Common Use Cases

### User Management System
Create, read, update, and delete users with proper authentication and authorization.

### User Profile Updates
Allow users to update their own profile information including password changes.

### Account Recovery
Soft delete allows for account recovery within a grace period before permanent deletion.

### Administrative Actions
Admins can manage all users, including viewing deleted accounts and restoring them.

### Bulk User Operations
The service layer makes it easy to perform bulk operations on users programmatically.

## Next Steps

Consider adding:
- User roles and permissions system
- Email verification workflow
- Password reset functionality
- Two-factor authentication
- User profile pictures/avatars
- Activity logging
- Pagination for user lists
- Advanced search and filtering
- User preferences/settings
