You might have discovered or developed an external learning application that you want to add to your online course. Or you might have a digital copy of your textbook that uses a format other than PDF. You can add external learning applications or textbooks to Studio by using a Learning Tools Interoperability (LTI) component. The LTI component is based on the IMS Global Learning Tools Interoperability version 1.1.1 specifications.
You can use an LTI component in several ways.
For example, the following LTI component incorporates a Cerego tool that students interact with.
Before you create an LTI component from an external LTI provider in a unit, you need the following information.
The launch URL (if the LTI component requires a student response that will be graded). You obtain the launch URL from the LTI provider. The launch URL is the URL that Studio sends to the external LTI provider so that the provider can send back students’ grades.
The LTI Passports policy key. This policy key has three parts: an LTI ID, a client key, and a client secret.
The LTI ID. This is a value that you create to refer to the external LTI provider. You should create an LTI ID that you can remember easily.
The LTI ID can contain uppercase and lowercase alphanumeric characters, as well as underscore characters (_). It can be any length. For example, you may create an LTI ID that is as simple as test_lti_id, or your LTI ID may be a string of numbers and letters such as id_21441 or book_lti_provider_from_new_york.
The client key. This value is a sequence of characters that you obtain from the LTI provider. The client key is used for authentication and can contain any number of characters. For example, your client key may be b289378-f88d-2929-ctools.school.edu.
The client secret. This value is a sequence of characters that you obtain from the LTI provider. The client secret is used for authentication and can contain any number of characters. For example, your client secret can be something as simple as secret, or it may be a string of numbers and letters such as 23746387264 or yt4984yr8.
To create the LTI Passports policy key, combine the LTI ID, client key, and client secret in the following format (make sure to include the colons):
For example, an LTI Passports policy key may resemble any of the following:
Creating an LTI component in your course has three steps.
On the Settings menu, click Advanced Settings.
In the field for the Advanced Module List policy key, place your cursor between the brackets.

"lti" (make sure that you include the quotation marks).

To register the external LTI provider, you’ll add the LTI Passports policy key to the course’s advanced settings.
On the Advanced Settings page, locate the LTI Passports policy key.
Place your cursor between the brackets.
Enter the LTI Passports policy key surrounded by quotation marks.
For example, the text in the LTI Passports field may resemble the following.
If you have multiple LTI providers, separate the values for each LTI Passports policy key with a comma. Make sure to surround each entry with quotation marks.
"test_lti_id:b289378-f88d-2929-ctools.umich.edu:secret", "id_21441:b289378-f88d-2929-ctools.school.edu:23746387264", "book_lti_provider_from_new_york:b289378-f88d-2929-ctools.company.com:yt4984yr8"
The page refreshes automatically. At the top of the page, you see a notification that your changes have been saved, and you can see your entries for the LTI Passports policy key.
|Accept grades past deadline||Specifies whether third party systems are allowed to post grades past the deadline. By default, this value is set to True.|
|Button Text||Enter a custom label for the button that launches the third-party LTI application.|
Enables you to add one or more custom parameters. For example, if you added an e-book, you can set a custom parameter that opens the e-book to a specific page. You could also use a custom parameter to set the background color of the LTI component.
Every custom parameter has a key and a value. You must add the key and value in the following format.
For example, a custom parameter may resemble the following.
To add a custom parameter, click Add.
|Display Name||Specifies the name of the component. This name appears above the component and in the course ribbon at the top of the page in the courseware. Unique, descriptive display names help you identify problems quickly and accurately for analysis.|
|Hide External Tool||Indicates whether you want to launch an external tool or to use this component as a placeholder for syncing with an external grading system. If you set the value to True, Studio hides the Launch button and any IFrames for this component. By default, this value is set to False.|
|LTI ID||Specifies the LTI ID for the external LTI provider. This value must be the same LTI ID that you entered on the Advanced Settings page.|
|LTI URL||Specifies the URL of the external tool that this component launches.This setting is applicable when Hide External Tool is set to False.|
|Open in New Page||Specify whether the problem opens in a new page. If you set this value to True, the student clicks a link that opens the LTI content in a new window. If you set this value to False, the LTI content opens in an IFrame in the current page. This setting is applicable when Hide External Tool is set to False.|
|Request user’s email||If Open in New Page is set to True, you can also request user information. Set this value to True to request the user’s email address.|
|Request user’s username||If Open in New Page is set to True, you can also request user information. Set this value to True to request the user’s username.|
|Scored||Indicates whether the LTI component receives a numerical score from the external LTI system. By default, this value is set to False.|
Specifies the number of points possible for the problem. By default, if an external LTI provider grades the problem, the problem is worth 1 point, and a student’s score can be any value between 0 and 1. This setting is applicable when Scored is set to True.
