Using Canvas External Apps (sometimes called LTI tools), instructors can easily add new features to Canvas courses. Canvas apps can be added to an individual course, or to all the courses in an institution. Once an app is installed in Canvas, instructors can link to the app from course modules, use it to create assignments for assessment tools, or add it to a course's navigation.
Some apps are not preconfigured at the institutional level but are available for you to install at the course level, and they are referred to as whitelisted apps. Installed apps are ready to be used within your course content areas or from the course menu whereas whitelisted apps require you to configure them for your course before they are available.
