Canvas provides an option to include a variety of external tools to the application that instructors can then make available for their classes. For your reference, these external tools are listed on the website EduAppCenter.com. As an administrator of this site, CTL has created a process to determine which of these tools can be made available (whitelisted) for use in Canvas courses.
Currently, CTL has whitelisted these external tools that are currently available for use in Canvas courses.
Please view the External Tools Rubric for Canvas LMS before submitting the Canvas External Tool Request Form. CTL uses this rubric to evaluate the risk and business need to determine if the request can be approved and the application be whitelisted.
