**Define error reponses for your APIs.**

## Overview

The Error Response allows you to specify a response that will be sent back to the client when an error occurs during the API endpoint execution. You are able to set a `Status Code`, `Response Header` as well as a `Response Body` to provide additional information to the client.

For the Error Response, choose a `4xx` status code for client errors and `500` for server errors.

Lastly, through the toggle you are able to allow further action blocks to be executed after a response has been sent.

## Example

Down below you can see an error response in it's most simple form:
