Hi Vaun,
You may be confusing the request type/method and how data is formatted in the request based on it.
If the type is GET, you would use a query string, which is appended to the URL.
If the type is POST, the properties you define in the contract are sent in the request body by default. You can further manipulate how this data is formatted and sent if you need to (sometimes you do), but most of the time you don't have to.
It sounds like you have an API endpoint you must POST data to.
Thanks,
