Order Desk is not an e-commerce platform, but an order management tool that connects multiple platforms. This means Order Desk is not used to import and manage products. You have to create your product in your SPOD app, download the CSV file and use the information in the platform of your choice (ex: Amazon, Etsy).
Once an order arrives in Order Desk from one of these platforms, if the SKU matches the product you created with SPOD, you will be able to ask for fulfilment and send it to us.
There is currently no automatic way to import a product from your SPOD App to the platform of your choice. It is all done via CSV files that you can find in your Product List. We do want to improve that process for you in a near future. We also plan on adding Dynamic printing.
Check out the steps in our tutorial on how to connect SPOD to Etsy using Order Desk. We explain how to publish a product in this use case and how to fulfill an order.
