R J Kirkwood commented on How can I see exact Errors via API testing.

this is what my json looks like:

{"order":{"customer":{"id":234692983},"financial_status":"pending","line_items":[{"variant_id":300018907,"quantity":1}]}}

which matches examples you give in api docs.

Please help: 

I am using the  ShopifyAPIClient .net library. and nowhere do i see a response back from shopify api as to what is missing/wrong.

All I get is error (422) when "dynamic createProductResponse = client.Post("/admin/orders.json", p1);" is executed.
