# Todo App API Documentation
## Version: 1.0
Base URL: `http://localhost:8080/api/v1`
## Overview
This API provides access to the Todo App functionality with versioned endpoints. The API uses API key authentication for protected endpoints, while some endpoints (like the marketplace) are publicly accessible.
## Authentication
### API Key Authentication
Most endpoints require an API key for authentication. The API key should be included in the `X-API-Key` header.
**Header:**
```
X-API-Key: todo_your_api_key_here
```
### Register a New User
**Endpoint:** `POST /api/v1/auth/register`
**Request Body:**
```json
{
"email": "user@example.com",
"password": "your_password",
"name": "John Doe",
"avatar_url": "https://example.com/avatar.jpg",
"settings": {
"theme": "dark",
"language": "en"
}
}
```
**Response:**
```json
{
"success": true,
"message": "User registered successfully",
"data": {
"user": {
"id": "user-uuid",
"email": "user@example.com",
"name": "John Doe",
"avatar_url": "https://example.com/avatar.jpg",
"settings": {"theme": "dark"},
"created_at": "2025-01-01 00:00:00",
"updated_at": "2025-01-01 00:00:00"
},
"api_key": "todo_abc123...",
"key_prefix": "todo_abc1"
}
}
```
**Important:** Store the API key securely. You won't be able to retrieve it again.
### Login
**Endpoint:** `POST /api/v1/auth/login`
**Request Body:**
```json
{
"email": "user@example.com",
"password": "your_password"
}
```
**Response (New API Key Created):**
```json
{
"success": true,
"message": "Login successful",
"data": {
"user": {
"id": "user-uuid",
"email": "user@example.com",
"name": "John Doe"
},
"api_key": "todo_abc123...",
"key_prefix": "todo_abc1"
}
}
```
**Response (Using Existing API Key):**
```json
{
"success": true,
"message": "Login successful",
"data": {
"user": {
"id": "user-uuid",
"email": "user@example.com",
"name": "John Doe"
},
"api_key_prefix": "todo_abc1",
"message": "Using existing API key"
}
}
```
**Note:** If you already have an active API key, the login will return the key prefix only (not the full key for security). You should store your API key securely after the first login.
### Creating an API Key (Legacy)
To create an additional API key, you can use this endpoint:
**Endpoint:** `POST /api/v1/auth/api-key`
**Request Body:**
```json
{
"email": "user@example.com",
"password": "your_password",
"name": "My App Key",
"scopes": ["read", "write"],
"expires_at": "2026-12-31 23:59:59"
}
```
**Response:**
```json
{
"success": true,
"message": "API key created successfully",
"data": {
"key": "todo_abc123...",
"prefix": "todo_abc1",
"name": "My App Key",
"scopes": ["read", "write"],
"expires_at": "2026-12-31 23:59:59"
}
}
```
### Scopes
API keys can have the following scopes:
- `read` - Read-only access to data
- `write` - Full access to create, update, and delete data
If no scopes are specified, the key will have full access.
## Public Endpoints
These endpoints do not require authentication.

"price": 0,
"is_free": true,
"created_at": "2025-01-01 00:00:00"

-H "X-API-Key: todo_your_key_here"
```
---
## API Documentation
The API is fully documented using the **OpenAPI 3.0** specification.
| Resource | Location |
|----------|----------|
| OpenAPI spec (canonical) | [`openapi/openapi.yaml`](openapi/openapi.yaml) |
| Generated HTML docs | `public/api-docs.html` (generated, see below) |
| Swagger/Postman import | Use `openapi/openapi.yaml` directly |
### Generating API Docs
From the project root:
```bash
# Generate HTML documentation page
php spark generate:api-docs
# Validate spec only (no file written)
php spark generate:api-docs --watch
# Open http://localhost:8080/api-docs.html after generating
```
The generated HTML uses [Redoc](https://redocly.com/redoc) for rendering and is
fully self-contained (the spec is embedded as a base64 data URI).
### Importing into Tools
- **Postman**: File → Import → choose `openapi/openapi.yaml`
- **Insomnia**: Import → From File → choose `openapi/openapi.yaml`
- **Swagger Editor**: Paste the contents of `openapi/openapi.yaml`
- **cURL/HTTPie**: Examples are in the OpenAPI spec under each endpoint
---
## Authentication
The API supports two authentication methods:
### 1. API Key Authentication (Primary)
```
X-API-Key: todo_abc123def456...
```
Used by most protected endpoints. Keys are obtained on registration or can be
created via `POST /user/api-keys`. Keys can be scoped (`read`, `write`) and
optionally expire.
### 2. JWT Bearer Authentication
```
Authorization: Bearer eyJ0eXAiOiJKV1Qi...
```
Available via the `/auth/jwt/*` endpoints. Tokens are valid for 1 hour and can
be refreshed via `/auth/jwt/refresh`.
### Authentication Flow
1. **Register** → receive API key + key prefix
2. **Login** → receive the same or existing API key
3. Include `X-API-Key` header on all protected requests
4. Optionally use JWT endpoints for short-lived bearer tokens

---
## Testing
### Running Tests
```bash
# Run all tests via composer
composer run test
# Or use phpunit directly
./vendor/bin/phpunit
# Run only API tests
./vendor/bin/phpunit tests/api
# With code coverage
./vendor/bin/phpunit --coverage-text
```
### Database Setup
Integration tests use your configured MySQL database. Make sure migrations are applied first:
```bash
php spark migrate
```
For a dedicated test database, uncomment the test DB config in `phpunit.xml.dist`:
```xml
<env name="database.tests.hostname" value="localhost"/>
<env name="database.tests.database" value="todo_app_test"/>
<env name="database.tests.username" value="root"/>
<env name="database.tests.password" value=""/>
<env name="database.tests.DBDriver" value="MySQLi"/>
```
Then create it and migrate:
```bash
mysql -e "CREATE DATABASE IF NOT EXISTS todo_app_test;"
php spark migrate
```
### Test Suite
| Directory | Description |
|-----------|-------------|
| `tests/api/ApiTest.php` | Full API integration tests (auth, CRUD, filtering, error handling) |
| `tests/unit/` | Unit tests for individual components |
| `tests/database/` | Database migration and seed tests |
| `tests/session/` | Session-related tests |
The API test suite covers:
- Registration and login
- Authentication errors (missing key, invalid credentials)
- Full CRUD for all resources (categories, projects, todos, recurring tasks)
- Category-todo / category-recurring-task linking
- Status and sort filtering
- Activity logging verification
- Ownership isolation (cross-user access denied)
- Validation error responses
- Pagination structure

## Database
### Schema Overview
The database consists of 12 tables:
| Table | Description |
|-------|-------------|
| `users` | User accounts (email, password hash, settings) |
| `api_auth_keys` | API keys (hashed, scoped, expirable) |
| `categories` | User-defined categories (with hex color) |
| `projects` | User-defined projects |
| `todos` | Tasks with status, due dates, project links |
| `todo_categories` | Many-to-many: todos ↔ categories |
| `recurring_tasks` | Recurring task templates (daily/weekly/etc.) |
| `recurring_task_categories` | Many-to-many: recurring_tasks ↔ categories |
| `activity_logs` | Audit trail (CRUD events, login, etc.) |
| `marketplace_themes` | Published theme definitions |
| `user_themes` | Per-user theme installations |
| `ai_chats / ai_messages / ai_providers / user_ai_settings / user_api_keys` | AI assistant features |
### Migrations
```bash
# Run all pending migrations
php spark migrate
# Roll back all migrations
php spark migrate:rollback
# Seed sample data
php spark db:seed SampleDataSeeder
```
---
## Development
### Adding a New Endpoint
1. Add the route in `app/Config/Routes.php`
2. Create the controller method (extends `App\Controllers\Api\BaseController`)
3. Create the model (extends `CodeIgniter\Model`)
4. Write migration if needed
5. Update `openapi/openapi.yaml` with the new endpoint
6. Run `php spark generate:api-docs` to regenerate HTML docs
7. Write tests in `tests/api/ApiTest.php`
### Updating Documentation
The **single source of truth** is `openapi/openapi.yaml`. After any API change:
1. Update the YAML spec
2. Run `php spark generate:api-docs`
3. Commit both files
### Available Spark Commands
```bash
php spark list # List all available commands
php spark generate:api-docs # Generate HTML docs from OpenAPI spec
php spark generate:api-docs --watch # Validate spec only
php spark migrate # Run database migrations
php spark db:seed # Seed the database
composer run test # Run all tests
php spark test:models # Test models
```
### Common Workflows
**New todo with category:**
```bash
KEY="todo_your_key_here"
# Create category
CAT=$(curl -s -X POST http://localhost:8080/api/v1/categories \
-H "X-API-Key: $KEY" \
-H "Content-Type: application/json" \
-d '{"name":"Work","color":"#3B82F6"}')
CAT_ID=$(echo $CAT | grep -o '"id":"[^"]*"' | head -1 | cut -d'"' -f4)
# Create todo with that category
curl -s -X POST http://localhost:8080/api/v1/todos \
-H "X-API-Key: $KEY" \
-H "Content-Type: application/json" \
-d "{\"title\":\"Finish report\",\"status\":\"open\",\"category_id\":\"$CAT_ID\"}"
```
**Filter and sort todos:**
```bash
curl -s "http://localhost:8080/api/v1/todos?status=open&sort=-due_date,title&per_page=5" \
-H "X-API-Key: $KEY"
```
---
## Contributing
1. Keep the OpenAPI spec (`openapi/openapi.yaml`) in sync with code changes
2. Run `php spark generate:api-docs --watch` to validate your YAML changes
3. Write tests for new endpoints
4. Run the full test suite before pushing
5. Follow CodeIgniter 4 conventions
