Connect Datafeed to Woocommerce Store + 2 Tasks

I have a datafeed from my supplier and I wish to connect to it on Woocommerce. It should import all the products from supplier. There is thousands of products so it needs to run perfectly. It also needs to display the images of the products on my store. Requirements - It needs to import automatically using a cronjob. We currently have this feed setup on Opencart, so we can show you how it's all setup currently and you can replicate similar. The Next job is that when a customer orders on our website, we need it to automatically place that same order on our suppliers website. Documentation is attached, so please have a read. Third job, we need to have an export button to download our order details in CSV format. I can give you an example of the file and how everything should display. They should only be exported if the status is 'PAID'. If it's shipped or completed then it doesn't need to export, as well as orders that payment was not received. Have a read through documentation and let me know if you have any questions.
