The VIVA LTI Tool is currently incompatible with Safari. We recommend using the LTI with Chrome or Firefox while we work to fix this. We apologize for the inconvenience.
The LTI tool allows any educator to browse and embed media objects alongside other content within assignments, or select content which comprises entire modules, lessons, or units. All users are able to search content added to VIVA Collections. Additionally, users can also browse or search content from Group Shared Folders and personal My Items libraries, if that content has been configured and made available.
Authentication and Account Provisioning
The tool provides automated authentication and new account provisioning, providing users with an "SSO like" experience. The LTI key/secret pair can also be configured to automatically add new users to a VIVA Group.
LTI Tool Preview Images
Some basic preview images of the tool have been included below. More details about using the LTI tool are available in the "Using the LTI tool" section of this guide.

Safari Login Issue
The Problem: I am using Safari and I can’t seem to login to the LTI Tool no matter what I do! I’ve even tried changing my password via reset password from email, and it still doesn’t work.
If you are using Safari 13+ the solution below will not work, due to updates with the way 3rd party cookies are handled. We recommend using Firefox or Chrome instead.
If you are using Safari 12 or earlier:
Check your cookie settings, and make sure you are allowing third party cookies. If you are strict about your cookie settings, you may need to whitelist vivaopen.oercommons.org
Close out of the LTI Tool
Open the Homepage in a new tab
Launch the LTI tool again
Safari does a lot to protect your privacy, and ensure third parties aren’t tracking you without your consent. Because of this, Safari won’t allow third parties to set cookie information, if it looks like you haven’t visited the site recently. This means we can’t set an SSO cookie if you’ve recently cleared your history, are using Safari for the first time, or are using Safari on a new device. Opening the VIVA Homepage will fix this problem, because it indicates to Safari that VIVA is a site you use intentionally.

Other Technical Documentation
The VIVA LTI Tool Provider conforms to the IMS LTI 1.1 Standard: https://www.imsglobal.org/specs/ltiv1p1/implementation-guide
We also support Content Item Message Extension, or Deep Linking: https://www.imsglobal.org/specs/lticiv1p0
The following parameters must be present in LTI launch request sent by the Tool Consumer
One of the following content identification parameters:
a.) resource_link_id (alphanumeric GUID)
b.) custom_redirect_url (full URL pointing to content on the VIVA platform, used in manual config only)
*If parameters do not conform exactly to the parameters listed above, the LTI tool will return a missing parameter error.
If this parameter is present it will be used to redirect a user when a resource is selected in the picker interface. Otherwise, the user is redirected to the specified VIVA content page.
If the cause of the error is known, the LTI tool will return an error message with debugging information. The most common cause of errors is missing LTI parameters.
