PHP

There is no official PHP package yet. On WordPress, use the plugin instead of raw cURL. Otherwise use cURL (or Guzzle) against the same HTTP API as Quick Start.

<?php
$base = getenv('JSONTOIMG_BASE_URL'); // e.g. https://app.jsontoimg.com
$key = getenv('JSONTOIMG_API_KEY');

$ch = curl_init($base . '/api/v1/render?wait=60');
curl_setopt_array($ch, [
  CURLOPT_POST => true,
  CURLOPT_HTTPHEADER => [
    'Authorization: Bearer ' . $key,
    'Content-Type: application/json',
  ],
  CURLOPT_POSTFIELDS => json_encode([
    'template' => '<design-id>',
    'format' => 'png',
    'layers' => ['headline' => ['text' => 'Hello']],
  ]),
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_TIMEOUT => 90,
]);

$body = curl_exec($ch);
curl_close($ch);
$job = json_decode($body, true);
echo $job['status'], ' ', $job['assetUrl'] ?? '', "\n";

Auth, errors, and wait/SSE behave like the API reference. For Node.js, use the typed SDK.
