Reverse Engineering the Denon Amplifier Web API

Posted by on 09 May 2021 in Web Authoring

We've just purchased a Denon AVR-X3700H AV amplifier. We're now reverse engineering how the web-based application works, and potentially the Android App too, so that we can detail what HTTP GET requests we can make when building our own automation applications.

Reverse Engineering the Denon Amplifier Web API
Screen capture of the Denon web-based user interface to their amplifier.

In General

The web application uses JQuery AJAX calls which prevents the client cache returning a previously fetched response by appending a timestamp parameter to each call with a key of '_' and a value in milliseconds since epoch.

Note, all GET requests are to an HTTPS server with a self signed certification that you will need to trust or exempt.

Status

Home

https://${HOST}:10443/ajax/home/get_config?type=${type}&_=${time}
The basic format of the 'home' get_config HTTP GET request.
URL Parameter Values
HOST The IP address or hostname of your amplifier on your network.
type An integer value from 1..1 inclusive, see next table below for responses for each type value.
time The time stamp in milliseconds.
'Home' Status URL Parameters.
