Learning Tools Interoperability (LTI): Developed by the IMS Global Learning Consortium, LTI is a standard that allows third-party learning applications to integrate seamlessly into LMSs. LTI provides a framework for the LMS to send user, role, and course information to the third-party tool, and for the tool to send grade data back to the LMS. It's widely supported by many LMSs, making it a versatile choice for integration.
