Errors

In this guide, we will talk about what happens when something goes wrong while you work with the API. Let's 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 with the inputs and do some rudimentary debuggingl
