The SoundCloud API will be dropping support for Extensible Markup Language (XML) responses. XML will be phased out on the following schedule:
Acceptheader. This default will be changed to JSON on December 1, 2014.
/tracks.xml) or an
Accept: application/xmlheader — will continue to be supported until December 15, 2014. After that point, only JSON responses will be supported.
SoundCloud has been using JSON exclusively for internal APIs for several years. Dropping support for XML in our public API will allow us to focus on providing consistent and reliable service.
If your app still uses XML responses, please start working to upgrade it to JSON immediately. If your app does not currently use XML responses, it should be unaffected by this change.
If you are unable to migrate your app from XML to JSON for some reason, we recommend accessing the SoundCloud API through a proxy server that converts JSON to XML.
Please let us know if you have any questions about this update via email.
