External applications, developed here at Harvard and elsewhere, can add functionality and content to your Canvas course website. You can explore available apps in Instructure's EduAppCenter, and you can learn more about using the Canvas App Center in the Canvas Guides.
To add apps to your Canvas site:
1) Navigate to Settings, click the Apps tab, and select the application you'd like to install
2) Click + Add App on the application page
3) If you already know the credentials for the app you're adding, enter them here and click Add App. If you're prompted for a Key and Secret and don't have the proper credentials, contact firstname.lastname@example.org to obtain this information and to complete the app installation
