Note that in the following sections, we give examples in CURL format. These can quickly be converted into any language of your choosing by using a tool such as Postman.
This is a two step process where step one would be to import our CURL example into Postman, and step two is to have Postman generate code in your preferred language.

Object-based POST requests use the relevant object key in the URL along with the headers outlined below:
