Depending on your institution's configuration, you may be launching Gradescope from Sakai using LTI version 1.3 or using the older version, LTI 1.0 combined with Sakai's custom API. An application programming interface (API) is a type of software that allows two apps to communicate with each other. Learning Tools Interoperability (LTI) is a type of software developed by IMS Global Learning Consortium specifically to allow learning systems, such as Sakai, to communicate with external systems, such as Gradescope.
Because the process for using Gradescope with Sakai can differ slightly based on which integration version you have, it's recommended that before you start using our LTI guides, you use one of the methods below to figure out whether your institution is launching Gradescope with LTI 1.0 + API or with LTI 1.3.
- Method 1 (recommended): Contact your institution's Sakai administrator or help@gradescope.com to ask if you're using Gradescope in Sakai with LTI 1.0 + API or LTI 1.3.
- Method 2: Check your deep-linking capabilities. To do that, on your course site in Sakai, click Lessons in the left sidebar. If you don't see Lessons in the sidebar, click Site Info > click Manage Tools > Select Lessons. On the Lessons page, click Add Content + > Add Learning App or Add External Tool. If Gradescope is listed under either menu as an app or a tool, you most likely have LTI 1.3. If Gradescope is not listed, you most likely have LTI 1.0 + API. Keep in mind that this is not a foolproof method and the best option is to contact either your admin or help@gradescope.com.
