Send Emails with PHP / Laravel

Learn how to send transactional emails using PostStack and PHP / Laravel.

1. Install the SDK

bash

# No external packages needed — uses built-in cURL

2. Initialize the client

php

$apiKey = 'sk_live_...';
$baseUrl = 'https://api.poststack.dev';

3. Send an email

php

<?php
$apiKey = getenv('POSTSTACK_API_KEY');

$payload = json_encode([
    'from' => 'hello@yourdomain.com',
    'to' => 'user@example.com',
    'subject' => 'Hello from PHP!',
    'html' => '<h1>Welcome!</h1>',
]);

$ch = curl_init('https://api.poststack.dev/v1/emails');
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $payload,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer ' . $apiKey,
        'Content-Type: application/json',
    ],
]);

$response = curl_exec($ch);
curl_close($ch);

echo $response;

Notes

Uses built-in PHP cURL — no Composer packages required
For Laravel, you can also configure PostStack as an SMTP transport in config/mail.php
