# Gateway Generated Responses

> Understand the meaning of the responses produced by the API gateway.

For some API requests, the response body is created by the gateway. This is usually the case in error situations or changing the response generated by the actual API server.

A header is sent through which you can check whether a request was generated by the gateway. If the response headers contain the following header, this indicates that the request was created by the gateway:

```
X-Jojapi-Gateway-Response: true
```

Let’s examine the responses generated by the gateway.

## **Error Messages**

Error messages contain a message. An example response is like this:

```
{"message":"Invalid Server"}
```

Below is a list of error messages:
