WooCommerce Order API always creates empty orders - wordpress

Question

Im playing around with Woo Commerce API (v3.4.4). I can get a product with:
curl -X GET \
'http://localhost/wp-json/wc/v2/products/7?oauth_consumer_key=ck_8cbe42fb09c04954a63994c22145270f27871dec&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1535381325&oauth_nonce=iApWJblA1A5&oauth_version=1.0&oauth_signature=9T1T43FvOpBzVBU+RQS90zMB/XM=' \
-H 'Cache-Control: no-cache' \
-H 'Postman-Token: bdb7f5c9-5719-4bcf-b4fc-38aed3bd5d08'
I get the response:

This works running the request using CURL on the command line, and running the request in Postman.
But now I try to create an order:
curl -X POST \
'http://localhost/wp-json/wc/v2/orders?oauth_consumer_key=ck_8cbe42fb09c04954a63994c22145270f27871dec&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1535382336&oauth_nonce=P8RWaD9DnZ9&oauth_version=1.0&oauth_signature=GFxtI7+gqbah5fu68gSdqL4V3fs=' \

When I run the above request with Postman, it creates an empty order and I get the response:

Bizarrely, when i run the EXACT same request with CURL on the command line, I get the response:
{"code":"woocommerce_rest_authentication_error","message":"Invalid signature - provided signature does not match.","data":{"status":401}}
If I run the request in Postman, but for "product_id" I use "this is a completely fake id" it still creates an empty order and responds with:

]
}
}
So I have a number of problems:
1/ No matter what product_id I use, the order that's created is always empty
2/ Even if I provide a fake product_id, an order is still created by Woo Commerce. Surely this is incorrect?
3/ Running the create order requests on the command line is giving different responses to Postman

Answer 1

I was missing:
-H 'Content-Type: application/json' \
from the request. I had this entered in Postman, but had not ticked the check box:
