How do we test API requests in a Rubygem to make sure that we're integrating correctly with our backend? We'll learn how to use stubs to fake out the request and test our code without any network requests.

The core of an API wrapper Rubygem is defining the Resource endpoints so developers can make requests cleanly. We'll also learn how to handle pagination for endpoints that return a list of results.
When you receive a JSON response from an API endpoint, it's really easy to convert this to a Ruby hash. But hashes don't feel very Ruby-ish when you're working with them and you can't add methods and treat them like objects.
