fulfilment api 404

[Simon62]

Hi

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.

{"fulfillment":{"location_id":3408011397,"tracking_number":null,"tracking_company":null,"tracking_url":null,"notify_customer":false,"line_items":[{"id":10668179128419}]}}

this just returns a 404

The order ID 

4181654831203, location and lineitem id matchup with the order

the only thing is this - 

any ideas how I can get round this?

fixed it (can't delete the post) - the fulfilment location was wrong afterall
