# Response Headers

When an API request is sent to the Mocklets server, it responds with the data set by the user for that API. But apart from the user data, Mocklets also returns other configuration data as response headers which help in debugging the request. Here are the headers which Mocklets returns.

### x-mocklets-src

This header lets what is the source of the response data. It can have 2 values `mock` or `proxy`. If the value is `mock` it means the data is fetched from the mock response provided the user, and if the value is `proxy`, it signifies that the response served to the user is from proxy server.

### x-mocklets-proxy-url

�This header is returned when the api request has been forwarded to a proxy server. It contains the url of the proxy server to which the request has been forwarded to.

### x-mocklets-delay

This header signifies the delay added to the api request (in seconds).
