The most recent mention I can find about the API is from March. Just wondering if you could provide an update on how that's coming along? I'd like to start a useful side project to learn mobile dev and I thought fuelly would be a great candidate. Providing fillup data in JSON format would empower your users to satisfy many of the wish list items that others have requested in the forums. Thanks!
We worked on the API for a while, but we have that project on hold right now. We're not close enough to release anything, and we don't have any immediate plans to start development on it again. Sorry about that.
There might still be ways to integrate with Fuelly. You could write a fuel tracking application that sends fuel-ups out via SMS, or out to the Fuelly import format.
