Hi Erjen ,
Thanks for you post.
Recurring Exports use the Action Scheduler included in WooCommerce. You can view the scheduled actions by accessing Tools -> Scheduled Actions from your site's Amin Dashboard.
Here you can view how our scheduled actions look on that page:
Code support is out of the scope of this forum, but you can read all the AS docs by accessing the above link. You can also find how we use it through the two classes you can find in the folder: /atum-export-pro/classes/Components/Queues
Hope this helps,
