I'm would like to update the internalNotes field of an existing orders with our shipping cost (Status = awaiting_shipment) before I complete the Marked Ship API.
I sent the API with the Order Number, OrderId and OrderKey (along with all the other required header fields) and I get the error below. We validated that the OrderId exists, so we aren't sure why we are getting this message. At first I was getting an 400 error because I didn't have all the required fields, so I added them. I am confused by the note "This call does not currently support partial updates; the entire resource must be provided in the body of the request". I added all the required fields to get the 200 status code, but now it can't find the ORderID.
Anyone have this issue?
"errorMessage": "Order 1004529220 not found. If you are attempting to create a new order please omit the orderId and try again."
