How do I integrate my domain with LTI 1.1 and 1.3 tools (like Google Assignments and Turnitin) with Echo?

Note: Echo has actively supported 1EdTech (formerly IMS Global's) LTI specification since it was created in 2010. Echo is an IMS-certified LTI 1.1 learning platform, which allows you to access other LTI-certified tools from within Echo.

In 2019, 1EdTech (formerly IMS) announced that its LTI 1.3 and LTI Advantage specifications, which provide additional functionality and security, would replace the soon-to-be deprecated LTI 1.1 specification. Echo continues to support LTI 1.1, and is also now an IMS-certified platform for LTI 1.3 and LTI Advantage.

Echo allows you to integrate entire domains with LTI tools, (like Turnitin and Google Assignments) so that teachers and other course authors can link to LTI activities.

This article covers how to integrate your domain, however please reference 1EdTech website to ensure your product is supported by 1EdTech.

Configure LTI 1.1 tools

For LTI 1.1 tool links, domain administrators configure Echo by adding an LTI 1.1 Tool in Domain settings. The tool definition includes a DNS hostname (such as api.turnitin.com), a public key, and a shared secret.

  1. Open the vertical menu in the toolbar of Domain Details.  
  2. Select Domain Settings.
  1. On the LTI 1.1 tools card, click Add.
  2. Provide:
    • The Hostname; use the URL that matches your location:
      • UK users: api.turnitinuk.com
      • All other users: api.turnitin.com
    • The LTI Key (your Turnitin account number)
    • The account Secret (configured by your Turnitin administrator in the Turnitin LTI integration setup).
    • Note: To integrate other LTIs, follow these same steps using the proper information. Consumer Keys and Shared Secrets are generated for individual institutions. Your institution should have the necessary information. 
  3. Save.

If you administer multiple Echo domains, you must configure this tool in each domain from which you launch the tool links.

A course author/instructor can also configure a tool on a single activity by providing a key and secret directly on the activity. This lets the instructor use a personal account for the tool without having to contact an administrator to configure a domain-wide credential.

Configure LTI 1.3 tools

Domain administrators configure Echo for LTI 1.3 tools in Domain settings:

  1. Click Add on the LTI 1.3 tools card. 

Provide the following:

  • Tool Title as you want it to appear.
  • A Description of the tool.
  • A DNS Tool hostname (such as api.turnitin.com).
  • The following fields provided by the tool: ClientID, OpenID connect login URL, Tool key set URL, Tool redirect URL.
  • In the User data sent at launch dropdown, check the boxes next to the user data you want included:
    • Given name
    • Family name
    • Display name
    • Email
  • In the LTI services dropdown, check the boxes next to the services included in the tool:
    • Assignment and grade
    • Names and role provisioning
    • Deep linking
  1. Scroll down and check the Domain-wide box to apply the integration to subdomains.
    • Example: If you administer a district domain that has several child domains that are schools, you can configure the tool in the district domain, check this box, and all courses in all the school domains can use the tool without manually configuring the tool in each school domain. (Note: This feature is not available in 1.1 tools.)
  2. Check the Enabled box to make the integration live; if this box is not checked, Echo ignores the tool when launching links.
    • Note: Disabling and enabling an integration is not available in 1.1 tools.
  3. Click Done and Save the new settings.
