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 OER Commons 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 an OER Commons Group.

Other Technical Documentation
The OER Commons 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 theOER Commons 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 OER Commons 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.
