Just like the previous two chapters, your homework in this chapter will involve finishing the refactor for the other two modules. You'll be doing your work in the -incomplete codebase for this chapter, just as you did earlier. You will need to set up a few new queries for user management as what was previously a query, find by email, now is the ID-based lookup and thus not a query. Try supporting querying by name, where a single input will match against either the first or last name.

For the credit-processing project, there isn't even a REST endpoint there yet, as it wasn't needed up to this point. For extra credit, if you feel so inclined, add an endpoint and support a way to lookup credit transactions by the card holder's name.
