shorter/sdk

PHP SDK for the shorter.sh URL shortener. Requires PHP >=8.1 and Guzzle 7.

Installation

composer require shorter/sdk

Quick Start

use Shorter\Sdk\ShorterClient;

$client = new ShorterClient(
    api_key: 'sk_your_key_here', // or set SHORTER_API_KEY env var
);

// Shorten a URL
$result = $client->shorten('https://example.com');
echo $result->short_url;  // https://shorter.sh/xK9mP2

// List your URLs
$list = $client->list(page: 1, limit: 50);
foreach ($list->urls as $url) {
    echo "{$url->short_url} → {$url->original_url} ({$url->click_count} clicks)\n";
}
echo "Total clicks: {$list->total_clicks}\n";

// Delete a URL
$client->delete('xK9mP2');

Authentication

The API key is resolved in order:

1. api_key constructor parameter
2. SHORTER_API_KEY environment variable

The key must start with sk_.

Analytics

// Overview analytics
$overview = $client->analytics->overview(
    start: '2024-01-01',
    end: '2024-01-31',
);
echo "Total clicks: {$overview->total_clicks}\n";
echo "Unique visitors: {$overview->unique_visitors}\n";

// Top URLs
foreach ($overview->top_urls as $url) {
    echo "{$url->short_url}: {$url->clicks} clicks\n";
}

// Breakdowns (country, device, browser, os, referrer)
foreach ($overview->country_breakdown as $item) {
    echo "{$item->value}: {$item->clicks} ({$item->percentage}%)\n";
}

// Per-URL analytics
$stats = $client->analytics->url('xK9mP2');
echo "Clicks: {$stats->summary->total_clicks}\n";
echo "Top country: {$stats->summary->top_country}\n";

// Per-URL with a specific breakdown dimension
$stats = $client->analytics->url('xK9mP2', dimension: 'country');
echo "Breakdown: {$stats->breakdown->dimension}\n";
foreach ($stats->breakdown->data as $item) {
    echo "  {$item->value}: {$item->clicks}\n";
}

// Detailed analytics (all breakdowns at once)
$detail = $client->analytics->url('xK9mP2', detail: true);
echo "Original URL: {$detail->url->original_url}\n";
foreach ($detail->breakdowns as $dimension => $breakdown) {
    echo "{$dimension}: {$breakdown->total} total\n";
}

Dimensions

Available breakdown dimensions: country, device_type, browser, os, referrer_domain, language
