Welcome to the FatSecret Platform REST API

We provide a REST-like API that allows developers to integrate FatSecret Platform features into their applications. The REST API can be used to build nutrition, diet and weight management solutions on any platform, including desktop client applications and mobile device solutions.
In order to start using the REST API please register for an account. Once you've registered you'll be able to attain an Application Consumer Key and associated Consumer Secret in order to start making calls to the API.
Authentication is central to the FatSecret REST API (we support both the OAuth Core 2.0 protocol and OAuth Core 1.0 protocol) so please take some time to read our guide to Authentication. Once you get your head around authentication you are ready to begin.
We look forward to seeing how you use the FatSecret REST API.
