Book wizzard

In order to link LuluDirect to my website I need someone with knowledge of json, java, etc., because it is by API. It is only easy when you have a Shopify or WooCommerce site, but I will have a Strato.es shop. Lulu is a self-publisher, and I am an author who wants to sell print-on-demand only for the moment this way worldwide. I have the programming codes downloaded from their site which you can do as well to see if you can get the job done.
