The FriendFeed API enables developers to interact with the FriendFeed web site programmatically. It is designed to give developers flexibility and freedom to make their own FriendFeed applications, so they can do things like create a new mobile phone experience, integrate FriendFeed into a blog or web application, or build an application that enables you to easily share photos to FriendFeed.
The FriendFeed API uses secure, standard technologies to ensure that you have control over what third party applications can do on your behalf. When you sign in to an application that uses the FriendFeed API, FriendFeed authenticates the application using OAuth, a technology that ensures you never need to provide your FriendFeed password directly to a third party site. If you ever stop using an application, you can easily revoke the application's access to your account at http://friendfeed.com/settings/applications.
You should never directly give out your FriendFeed password to a third-party web site. Web sites that use the FriendFeed API should always direct you to friendfeed.com for authentication.
Some non-web applications, including iPhone applications and installed desktop applications, will ask for your FriendFeed password. Make sure to only provide your password to applications that you have personally installed and trust.
You can revoke access previously granted to an individual web or installed application by going to http://friendfeed.com/settings/applications. (Note that if you change your FriendFeed password, this will also cause all of your installed applications to lose access.)
If you have used an application that uses remote keys, you can reset your key on your remote key page.
A remote key is like a valet key that gives third-party applications limited access to interact with your FriendFeed account. While there are limits to what can be done using a remote key, you should still only give your remote key to a site or application that you trust. See your remote key and the remote key FAQ.
We're glad you asked! By all means take a look at the FriendFeed API documentation, and have at it!
OAuth is an authentication protocol that allows you to authorize a third-party application to interact with FriendFeed on your behalf without sharing your password. Learn more about OAuth.
