Errors
What happens when something goes wrong while you are interacting with the API? Mistakes happen, so let's take a look at some status codes and error types you might encounter.
You can tell if your request was successful by checking the status code when receiving an API response. If a response comes back unsuccessful, you can use the error type and error message to figure out what has gone wrong and do some rudimentary debugging.
