Configuration

Create a .env file in your project root:

N8N_BASE_URL=https://your-n8n-instance.com

The .env file is automatically loaded when you use the Config class.

Backend (ajax.php)

<?php

require 'vendor/autoload.php';

use Digilopment\N8NClient\Services\Handler;

$data = [
    'tema' => $_POST['tema'] ?? null,
];

$errorData = [
    'message' => 'Chyba pri generovaní',
    'details' => null,
];

(new Handler())
    ->setData($data)
    ->handleJson('generuj-obsah')
    ->getAll()
    ->ifError($errorData)
    ->getData();
