Send with PHP

Use the official PHP SDK.

1. Install

composer require resend/resend-php

2. Point the SDK at Postwave

RESEND_BASE_URL=https://post-waves.com

3. Send an email

<?php
require __DIR__ . '/vendor/autoload.php';

$client = Resend::client(getenv('API_KEY'));

$email = $client->emails->send([
  'from' => 'Acme <onboarding@yourdomain.com>',
  'to' => ['delivered@postwave.test'],
  'subject' => 'Hello world',
  'html' => '<strong>It works!</strong>',
]);

echo $email->id;

4. Run it

API_KEY=pw_xxxxxxxxx php send.php

You'll get back { "id": "…" }. Open Emails in the dashboard to see it arrive and its delivery status update.

Tip: delivered@postwave.test is a test address: it simulates a delivery without emailing anyone. Swap in a real address when you're ready.
