The tutorial never has had a connector example. It would be helpful to include one, especially one that showed how to use what was conceptually explained in the tutorial chapter. This example could be created in a way that involves interfacing with a 3rd party API, but should not be limited to this. Think of it as "fielder's choice", a baseball term that leaves the choice and details up to you.
I guessed on the estimate for how long it would take to create such an example, then document it. Feel free to adjust this accordingly.
