Posting JSON in Ruby with HTTParty Returns invalid_request

Question

It seems that my post is reaching the host, however it may be formatted incorrectly? Not coming in as JSON?

The host's result is presenting me with an error Code: invalid_request Message: Validation failed on the request.

Host Docs:

This means that Automatic Ordering didn't have enough information to place the order. This almost always occurs because you haven't fully filled out your Amazon account information on your Automatic Ordering section.

My error result includes the following:

According to Zinc Docs you should send json object in body but you are sending json array. To send JSON Object, you should start your body with curly braces "{}" and not square brackets "[]"

@ZincResult=HTTParty.post(zincUrl,
    :body => {.........}.to_json,
    :headers => { 'Content-Type' => 'application/json' } )
