README

Modern, lightweight PHP SDK for Freelo API.

Features

PHP 8.1+ with strict types
PSR-18/17/7/16 compliant (bring your own HTTP client)
Full API coverage (projects, tasks, files, comments, time tracking, etc.)
Dynamic credentials with server-safe per-request switching
Low-level call() method for arbitrary API endpoints
Automatic pagination support
Rate limiting detection
Typed exceptions for error handling

Installation

composer require freeloapp/php-sdk

Install an HTTP client (e.g., Guzzle):

composer require guzzlehttp/guzzle php-http/guzzle7-adapter nyholm/psr7

Quick Start

use Freelo\Sdk\Freelo;
use Freelo\Sdk\Auth\ApiKeyCredentials;

$freelo = new Freelo(
    new ApiKeyCredentials('your-api-key', 'your-email@example.com'),
    userAgent: 'MyApp/1.0',
);

// List projects
foreach ($freelo->projects()->list() as $project) {
    echo $project->name . "\n";
}

// Create a task
$task = $freelo->tasks()->create(
    projectId: 123,
    tasklistId: 456,
    data: ['name' => 'New task', 'priority_enum' => 'h']
);

Authentication

Get your API key from Freelo Settings (scroll to API section).

use Freelo\Sdk\Auth\ApiKeyCredentials;

// Using environment variables (recommended)
$credentials = new ApiKeyCredentials(
    apiKey: getenv('FREELO_API_KEY'),
    email: getenv('FREELO_EMAIL')
);

$freelo = new Freelo($credentials, userAgent: 'MyApp/1.0');

Usage Examples

Projects

$projects = $freelo->projects()->list();           // List active projects
$project = $freelo->projects()->get(123);          // Get project by ID
$freelo->projects()->archive(123);                 // Archive project
$freelo->projects()->activate(123);                // Activate archived project

// Paginated results
$result = $freelo->projects()->getAll(['p' => 0]);
echo "Total: " . $result->getTotal();

Tasks

$tasks = $freelo->tasks()->listInTasklist(123, 456);  // List tasks in tasklist
$task = $freelo->tasks()->get(789);                    // Get task by ID
$freelo->tasks()->finish(789);                         // Mark as complete
$freelo->tasks()->activate(789);                       // Reopen task
$freelo->tasks()->move(789, 999);                      // Move to another tasklist
$freelo->tasks()->addComment(789, 'Comment text');     // Add comment

Time Tracking

$freelo->timeTracking()->start(taskId: 123, note: 'Working');
$report = $freelo->timeTracking()->stop();

// Manual work report
$freelo->workReports()->create(123, [
    'minutes' => 120,
    'date_reported' => '2024-01-15',
    'note' => 'Development work',
]);

Files

$freelo->files()->uploadToTask(taskId: 123, filePath: '/path/to/file.pdf');
$freelo->files()->download(fileId: 456, destination: '/path/to/save.pdf');

Dynamic Credentials

Per-request credentials (server-safe)

Use withCredentials() to create an isolated instance with different credentials. Each derived instance has its own client and state — safe for concurrent requests in multi-tenant server applications.

// Shared base instance (e.g. in a service provider)
$freelo = new Freelo(new ApiKeyCredentials(
    apiKey: 'default-key',
    email: 'default@example.com'
));

// Per-request — fully isolated, concurrency-safe
$userFreelo = $freelo->withCredentials(new ApiKeyCredentials(
    apiKey: $user->apiKey,
    email: $user->email
));

// Optionally override userAgent per tenant
$userFreelo = $freelo->withCredentials(
    new ApiKeyCredentials($user->apiKey, $user->email),
    userAgent: 'TenantApp/1.0',
);

$projects = $userFreelo->projects()->list();

For simple single-user scripts, you can swap credentials in place with setCredentials():

$freelo->setCredentials(new ApiKeyCredentials(
    apiKey: 'new-key',
    email: 'new@example.com'
));

// With userAgent override
$freelo->setCredentials(
    new ApiKeyCredentials('new-key', 'new@example.com'),
    userAgent: 'MyApp/2.0',
);

Note: setCredentials() mutates the shared instance and is not safe for concurrent requests.

Lazy initialization

The SDK supports creating a client without credentials upfront. Credentials can be provided later via setCredentials() — validation is deferred to the first API request.

$freelo = new Freelo();

// ... later, when credentials are available
$freelo->setCredentials(new ApiKeyCredentials(
    apiKey: $apiKey,
    email: $email
));

$freelo->projects()->list(); // works

Low-level API Calls

Use call() to hit arbitrary API endpoints not yet covered by typed resource classes:

// GET request with query parameters
$response = $freelo->call('/projects', 'GET', params: ['p' => 0]);
$data = $response->json();

// POST request with body
$response = $freelo->call('/projects/123/tasklists/456/tasks', 'POST', data: [
    'name' => 'New task',
    'priority_enum' => 'h',
]);

// Also available on derived instances
$userFreelo = $freelo->withCredentials($credentials);
$response = $userFreelo->call('/users/me', 'GET');

Pagination

use Freelo\Sdk\Http\Paginator;

// Auto-paginate through all results
foreach (Paginator::fetchAll(fn($p) => $freelo->projects()->getAll(['p' => $p])) as $project) {
    echo $project->name . "\n";
}

// Manual pagination
$page = $freelo->tasks()->getAll(['p' => 0]);
echo "Page {$page->getPage()} of " . ceil($page->getTotal() / 20);
if ($page->hasNextPage()) {
    $nextPage = $freelo->tasks()->getAll(['p' => $page->getNextPage()]);
}

Error Handling

use Freelo\Sdk\Exception\{
    ApiException,
    AuthenticationException,
    NotFoundException,
    RateLimitException,
    ValidationException
};

try {
    $project = $freelo->projects()->get(999);
} catch (NotFoundException $e) {
    // Resource not found (404)
} catch (AuthenticationException $e) {
    // Invalid credentials (401)
} catch (RateLimitException $e) {
    // Rate limited (429) - retry after $e->getRetryAfter() seconds
} catch (ValidationException $e) {
    // Invalid input (422)
} catch (ApiException $e) {
    // Other API errors
}

Rate Limiting

The API allows 25 requests/minute. The SDK tracks limits automatically:

$limiter = $freelo->getClient()->getRateLimiter();
if ($limiter->isLimitExceeded()) {
    sleep($limiter->getSecondsUntilReset());
}

Custom HTTP Client

use GuzzleHttp\Client;
use Http\Adapter\Guzzle7\Client as GuzzleAdapter;

$httpClient = new GuzzleAdapter(new Client(['timeout' => 30]));
$freelo = new Freelo($credentials, httpClient: $httpClient);

Caching (Optional)

use Symfony\Component\Cache\Psr16Cache;
use Symfony\Component\Cache\Adapter\FilesystemAdapter;

$cache = new Psr16Cache(new FilesystemAdapter('freelo', 3600));
$freelo = new Freelo($credentials, cache: $cache);

Development

composer install     # Install dependencies
composer test        # Run tests
composer phpstan     # Static analysis
composer check       # Run all checks

Requirements
