Title: JSON has objects, not hashes

It’s confusing for the docs to refer to “hashes” when the API’s representation format is JSON, and in JSON parlance that data structure is called an “object” not a “hash”. Since users of the API may be using various languages that may or may not have a data structure called a “hash” it’s better to use the platform-agnostic parlance of JSON.
