I'm having an issue fulfilling items on orders via the fulfillments.json api.
as far as I can tell, this functionality used to work. I'm not sure when it ceased to do so.
We have items that can be added to an order as a service - a spray on a product. They are not a physical product and have no tracking.
When fulfilling via the api, i'm getting a 404 error every time. I can only think this is a limitation of the type of product. Is there a way to continue fulfilling this via the api. it causes big problems issueing refunds when the despatch hasn't gone through in the first instance.
