Welcome to the Freesound APIv2 documentation!
The APIv2 brings many new features such as OAuth2 authentication, sound uploads and improved search options. APIv2 is still in a beta phase so it might not be completely reliable. Documentation is still incomplete and we haven’t released any client libraries yet. Therefore, use it at your own risk! ;)
We recommend you to have a look at the (still incomplete) Resources (APIv2) page and to have a look at the browseable API (http://www.freesound.org/apiv2) to quickly understand how the new API works. You’ll need to be logged in Freesound to be able to use the browseable API.
In order to start using APIv2 you’ll need an API credential that you can request in (http://www.freesound.org/apiv2/apply). API credentials given for APIv2 can also be used for APIv1. If you have any questions or doubts you can post them in our mailing list http://groups.google.com/group/freesound-api.
