As another question. Is there documentation on how to create an order programmatically? Or is it just: Order > Add Items > Advance State > Add Shipment > Add Payments > Finalise

I’d try to use this: https://github.com/solidusio/solidus/blob/main/core/lib/spree/core/importer/order.rb If you pass the right params, it will do all the work. Its specs might help as documentation.

Thanks!
