-If a web hook is invalid, it'll never hit your loops - so you're only dealing with valid hook requests.
+If a web hook is invalid, it'll never hit your loops - so you're only dealing with valid hook requests. All hash keys will be strings (I normally prefer symbols, but hashes within hashes had string keys, so opting with that as a default).
 
 Also: it's best to keep your loops short and sweet - don't put business logic in your initializer, but somewhere else where you've got some test coverage. As a rule of thumb, if you've got more than one line inside a loop block, then you should probably consider whether that code could be somewhere else.
 
 Finally, make sure Chargify is set up to send its hooks your way. This library adds a route that accepts POST requests to @/chargify/hooks@ - so if your site is @www.example.com@, then you'll want to tell Chargify to send hooks to @http://www.example.com/chargify/hooks@.
