Learning Tools Interoperability (LTI) is a standard developed by 1EdTech formerly known as IMS Global Learning Consortium at the time of creation. It enables seamless integration between learning systems and external systems. In its current version, v1.3, this is done using OAuth2, OpenID Connect, and JSON Web Tokens. For example, a Learning Management System (LMS) may use LTI to host course content and tools provided by external or third-party systems on a website without requiring a learner to log in separately on the external systems. The LTI will also share learner information and the learning context shared by the LMS with the external systems.
