WooCommerce API: No order data specified to edit order

Yesterday I received my Barcode scanner, after a little playing scanning everything in sight I got to work on programming a Raspberry PI in Python to use the barcode scanner to update orders in WooCommerce.

I’m not going to go into full details in this post on how. but I will write it up soon.

A BIG problem I hit though was updating orders using the WooCommerce API. I kept getting error code 400 ‘No order data specified to edit order’. I’d followed the example but changed it to fit my code i.e dont print the output but return it for error checking.

Searching google for that exact phrase gave just 1 result, and it’s someone commenting they are getting the error with no response (and it’s 4 months old on a 2 year old post).

After looking through the API code and trying to follow along (I’m not the best programmer but I can generally follow what it’s trying). I found it looking for ‘order’

So after looking at how the bulk update is done and with a bit of playing I found that instead of

data = {'status': 'completed'}

you need

data = {"order":{"status":"completed"}}

Hey Presto it works. My specific code is now

def WooCommerceUpdateOrder(order, data):
   global wcapi
   putstring = "orders/%s" % order
   result = wcapi.put(putstring, data)
   return result

which is called using

data = { 'order': { "status": "completed" } }
updateresult = WooCommerceUpdateOrder(order, data)

Hope this helps someone.  I’ll post the full python program for the barcode reader later in the week. Basically it uses a PI, PI LCD Screen with 4 buttons, Barcode Reader, Speakers. 🙂

  1. Thanks! Just ran into this problem and found your page by searching "No order data specified to edit order". Saved me a bunch of time. It's kind of a pain sometimes how the WC api responds with and expects the data bound to an attribute on the response objects.
