Quizlet Flashcards

The Quizlet API lets developers use Quizlet's vast database of over 200 million flashcards covering every possible subject. With over 2 million registered users and more than 7 million flashcard sets, Quizlet is the largest flash cards and study games website. The Quizlet API lets users search, download, edit and upload flashcard sets for use in their own applications. Developers can also mark sets as favorites (which show up on the website), create, edit and join groups that can be used for grouping both classmates and sets. Developers can also search for definitions and more. The API uses RESTful calls and responses are formatted in JSON. Quizlet's API also suppors OAuth2 which allows developer to authenticate and act on behalf of Quizlet users.
