Creating orders with wp-cli. Need syntax for order_meta.

I’m using wp-cli to create orders from a script. It’s working great at this point, but now I need to add a custom field to my orders. My understanding is that I should be able to pass that along using order_meta, but I’m unsure of the syntax I should use to specify a name and a value. I can’t find it documented anywhere.

My order creation command looks like this:

wp wc order create --path=/home/mqwr/public_html/wordpress --status='processing' --customer_id=324 --billing_address.first_name='Chester' --billing_address.last_name='Tester' --billing_address.address_1='123 Testing Lane'

... blah blah blah more fields and values and then ...

shipping_address.country='US' --note='Ship Via: FedEx Ground' --line_items.0.product_id=119 --line_items.0.quantity=1 --line_items.1.product_id=130 --line_items.1.quantity=2

So I need to add “–order_meta=[insert solution here]”.

The name will be “hubpoid” and the value will be a 16 digit number.

Any ideas?

Thanks,
Marshall
