I'm having trouble writing a PHP listener script for Paypal notification webhooks. I simply need a script to listen for and request the Paypal json data. I have created one for Stripe successfully, thanks to plenty of online documentation. This is what I have:

<?php require_once('./lib/Stripe.php');
    Stripe::setApiKey("my_secret_stripe_key");

    $input = @file_get_contents("php://input");
    $event_json = json_decode($input);

    // then I request the json data from a Stripe event... //
    $event_json->type == 'charge.succeeded'
    // etc... //
?>

I just need something similar to handle Paypal event json.

PayPal just released a new version, PayPal PHP-SDK 1.4.0; this has a webhook listener.

https://github.com/paypal/PayPal-PHP-SDK/releases/tag/v1.4.0

The file is ValidateWebhookEvent.php

It is in the samples.
PayPal-PHP-SDK/paypal/rest-api-sdk-php/sample/notifications/ValidateWebhookEvent.php

The docs are here
