IFTTT broke up with Twitter last year, but the service based on linking your various social accounts with cause-and-effect "recipes" is adding Twitter back into its fold.
IFTTT--which stands for "if this, then that"--severed ties with Twitter last September when the micro-blogging service changed the rules on third-party API usage. IFTTT lets users connect their accounts on Evernote, LinkedIn, Facebook, Dropbox, and dozens of other sites. Users can then use recipes, or create triggers on one site that lead to actions on another. Popular IFTTT recipes like "if I send a tweet, post it to Facebook" were disabled with Twitter's API changes. IFTTT told The Verge that the two sites were able to come to an agreement about which triggers violated Twitter's guidelines and which are allowed.
Now IFTTT users will be able to trigger actions by composing new tweets, using hashtags, posting links, and favoriting other tweets. Some of the actions, or end results, available to IFTTT users are tweeting images, adding users to lists, posting tweets, and updating bios and profile photos. Users will also be able to create recipes for Twitter, like "if I favorite a link, save it to Pocket."
IFTTT has been growing steadily since its inception in December 2010. The service started out as desktop-only but recently rolled out an iOS app and joined with high-profile partners like the New York Times. When a major site or service generates enough recipes either on its own or through user submissions that it warrants its own channel, it gets one. The New York Times joined BuzzFeed and ESPN in creating an official IFTTT channel, boosting the service's profile in the process.
IFTTT is still considered a beta product, but if its usefulness increases across platforms, then the general public might jump on board.
