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.

Before reaching out to support with an issue, please carefully check your code for any variables incorrectly typed and headers not correctly passed along.
