This library allows a tool provider (your app) to receive LTI launches from a tool consumer (i.e. LMS). It validates LTI launches and lets an application interact with services like the Names Roles Provisioning Service (to fetch a roster for an LMS course) and Assignment Grades Service (to update grades for students in a course in the LMS).

This library was forked from IMSGlobal/lti-1-3-php-library, initially created by @MartinLenord. Packback found the library immensely helpful and extended it over the years. It has been rewritten by Packback to bring it into compliance with the standards set out by the PHP-FIG and the IMS LTI 1.3 Certification process. Packback actively uses and maintains this library.
