WooCommerce Zapier send data asynchronously (rather than immediately)

wczapier.php

<?php
/*
The following code will tell the WooCommerce Zapier extension (v1.7.x - v1.9.x) to send data to 
Zapier asynchronously via WordPress cron, rather than sending the data immediately.

This snippet does not apply for WooCommerce Zapier version 2.0+, which uses WooCommerce core's webhook devliery mechanism instead.

Please note that we only suggest doing this if your WP-Cron facility is working reliably.

Save this file as wczaper.php and place it in your wp-content/mu-plugins/ directory.
