This is a simple PHP library for interacting with v3 of the Bit.ly API from a PHP application. The client supports the new OAuth endpoints, as API key authentication has been deprecated. Though not directly supported by Bit.ly, the library is endorsed for use on the Bit.ly developer site. The Bit.ly API allows developers to implement programmatic shortening, sharing, and tracking of links (URLs). Unique user-level and aggregate links can also be created to let users view complete, real-time traffic and referrer data, as well as location and metadata.
