Check if Mollie payment is paid - php

Question

I have been stuck on this for weeks now so I'm dropping my question here, hopefully someone can help me. I have a website where people can sell their car. You buy an advertisement and you can upload your vehicle. I have integrated Mollie Payment API so people can pay with iDeal, but it doesn't seem to read the payment status.
When the payment has been successful, my system doesn't give out an advertisement. How can I check if the payment has been successful and then automatically give out an advertisement if the order has been paid?
This is the code that processes the payments:
<?php
namespace AutoListingsFrontend;
require_once __DIR__ . "/../mollie-api-php/vendor/autoload.php";
require_once __DIR__ . "/../mollie-api-php/examples/functions.php";

add_action( 'auto_listings_send_to_gateway', array( $this, 'send_to_gateway' ) );

Solved. I used the Mollie Webhook to check the status of the payment: https://github.com/mollie/mollie-api-php/blob/master/examples/payments/webhook.php.
