How do I configure an external app for a course using XML?
One way to configure an app for a course is by using XML.
To learn more about configuring external apps, visit the Edu App Center.
Note: Configuring an external app is a course permission. If you cannot configure an external app, your institution has restricted this feature.
Select the Configuration Type drop-down menu and set the configuration type to Paste XML.
Enter the name of the app in the Name field . Enter the consumer key in the Consumer Key field  and the shared secret in the Shared Secret field . This key and shared secret will be provided by the vendor or (if using the Edu App Center) provided by the website.
Note: There are some apps that do not require a consumer key or shared secret, so pay attention to the configuration directions.
Copy the XML code in the paste XML here field . Click the Submit button to link the app .
View the linked app. To manage the app, click the Settings icon .
To edit the app, click the Edit link . To manage where the app displays in Canvas, click the Placements link . To delete the app, click the Delete link .
Note: When you click the Placements link, you may see a No Placements Enabled message. This message indicates that the app does not have any specified placements within Canvas. However, the app will still work as intended.
