Q: I received a "Duplicate nonce to one already received" error message and could not access my book.
A: This error happens when a user clicks on the same link too many times, making immediate duplicate calls. Try again with a single click.
Q: I added the VitalSource link to my course, but am receiving an “Invalid oauth consumer key error.”
A: The VitalSource tool may have been added as a link instead of an “external tool.” Delete the link added and re-add, ensuring “external tool” is selected. If you are still experiencing issues, please ask your LMS/VLE Admin to verify the Key/Secret is correct and does not have any leading or trailing white space.
Q: Do you have any handy guides to help me install the LTI Tool?
Q: How can I find my key and secret?
A: The Integration Manager will provide the key and secret to the LMS/VLE administrator or campus technology. Faculty should not need access to this information.
Q: What is a course book pairing file?
A: A course book pairing file matches the course materials to each course.
