after trying different ways of using the API from sightengine I can' get it to work, I followed the instructions on their site , installing via composer, but when I try to use it, I get the Class not found error in apache:
PHP Fatal error: Uncaught Error: Class 'Sightengine\\SightengineClient' not found in /var/www/html/photobooth/app.php
PHP file:
<?php
use Sightengine\SightengineClient;
$client = new SightengineClient('xxxxxxx', 'xxxxxxxxx');
