Subsonic API

The Subsonic API allows anyone to build their own programs using Subsonic as the server, whether they're on the web, the desktop or on mobile devices. As an example, the Subsonic Android and iPhone apps are built using the Subsonic API.

Feel free to join the Subsonic App Developers group for discussions, suggestions and questions.

Introduction

The Subsonic API allows you to call methods that respond in REST style xml. Individual methods are detailed below.

Please note that all methods take the following parameters:

Parameter	Required	Default	Comment
u	Yes		The username.
p	Yes		The password, either in clear text or hex-encoded with a "enc:" prefix.
v	Yes		The protocol version implemented by the client, i.e., the version of the subsonic-rest-api.xsd schema used (see below).
c	Yes		A unique string identifying the client application.

For example:

http://your-server/rest/getIndexes.view?u=joe&p=sesame&v=1.1.0&c=myapp, or
http://your-server/rest/getIndexes.view?u=joe&p=enc:736573616d65&v=1.1.0&c=myapp

Starting with API version 1.2.0 it is deprecated to send the username and password as part of the URL. Instead, HTTP Basic authentication should be used. (Only preemptive authentication is supported, meaning that the credentials should be supplied by the client without being challenged for it.)

Note that UTF-8 should be used when sending parameters to API methods. The XML returned will also be encoded with UTF-8.

All methods (except those that return binary data) returns XML documents conforming to the subsonic-rest-api.xsd schema. This schema (as well as example XML documents) can be found at http://your-server/xsd/

Error handling

If a method fails it will return an error code and message in an <error> element. In addition, the status attribute of the <subsonic-response> root element will be set to failed instead of ok. For example:

   <?xml version="1.0" encoding="UTF-8"?>
   <subsonic-response xmlns="http://subsonic.org/restapi"
                      status="failed" version="1.1.0">
       <error code="40" message="Wrong username or password"/>
   </subsonic-response>
            

The following error codes are defined:

Code	Description
0	A generic error.
10	Required parameter is missing.
20	Incompatible Subsonic REST protocol version. Client must upgrade.
30	Incompatible Subsonic REST protocol version. Server must upgrade.
40	Wrong username or password.
50	User is not authorized for the given operation.
60	The trial period for the Subsonic server is over. Please donate to get a license key. Visit subsonic.org for details.
70	The requested data was not found.

Versions

This table shows the REST API version implemented in different Subsonic versions:

Subsonic version	REST API version
3.8	1.0.0
3.9	1.1.1
4.0	1.2.0
4.1	1.3.0

Note that a Subsonic server is backward compatible with a REST client if and only if the major version is the same, and the minor version of the client is less than or equal to the server's. For example, if the server has REST API version 2.2, it supports client versions 2.0, 2.1 and 2.2, but not versions 1.x, 2.3+ or 3.x. The third part of the version number is not used to determine compatibility.
