Update Custom Order Field using RESTful API

I’ve been trying to update a custom order field I created using the REST API with no luck, I couldn’t find any details on the subject in the documentation. There are options to update custom fields in other sections but not for an order. Would you guys guide me in the right direction with a tested code!
Thank you

Unfortunately we don’t yet support custom fields on Orders through the REST API. You can access them through the Legacy XML-RPC API until we get that feature completed.

Thank you for your reply Tom!
Any technical reason for that or it’s just something in progress?
Thank you


The REST implementation has only just been release months ago and is still in development. The will be adding features progressively.

Ok, thank you!
