Administrator’s Guide — Canvas LTI 1.3 (Dynamic Registration)

Plagiarismcheck.orgCanvasAdministrator’s Guide — Canvas LTI 1.3 (Dynamic Registration)

This guide walks Canvas administrators through enabling the PlagiarismCheck.org LTI 1.3 integration using dynamic registration. Once enabled, instructors can attach PlagiarismCheck to any assignment, students submit their work directly inside Canvas, and originality reports plus grades flow back automatically.

Before you start

You’ll need:

  1. Administrator access to your Canvas instance.
  2. An active PlagiarismCheck.org organisation account with Admin (Owner) role. If you don’t have Admin access, but you need it, please contact us here.

Step 1: Navigate to Integrations

Step 2: Generate your registration URL

  • On the PlagiarismCheck registration page, select Dynamic tab, click  Generate registration URL  and then  Copy.

Step 3: Open Developer Keys in Canvas

  • Sign in to Canvas as a root administrator. Open the  Admin  menu, choose your institution, then in the left navigation click  Developer Keys.

Step 4: Start LTI Registration

  • Click the  + Developer Key  dropdown in the top right of the page and choose  + LTI Registration . Canvas opens the  Register App  dialog.

  • Paste your URL into  Dynamic Registration URL  and click  Continue.

Step 5: Review the tool’s permissions

  • Canvas shows a  PlagiarismCheck.Org LTI 1.3 Settings  panel. Leave the three  Permissions  checkboxes ticked — they’re what lets PlagiarismCheck post grades back and read assignment data:
    • Can create and update submission results for assignments associated with the tool.
    • Can create and view assignment data in the gradebook associated with the tool.
    • Can view submission data for assignments associated with the tool.

Step 6: User data and placements

  • Keep  User data shared with this tool  set to  All user data. Canvas will share Canvas ID, Name, First Name, Last Name, SIS ID, Avatar and Email address — all required so originality reports can be tied to the correct student.
  • Under  Placements , confirm  Link selection  is on. The Title field can be left as PlagiarismCheck.org LTI 1.3 or shortened to whatever you’d like instructors to see in the picker.

Step 7: Enable & close

  • Click  Enable & Close. The key appears in the Developer Keys list with state  On  — that’s what makes it available across the account.

Step 8: Add new App

  • Copy  Client ID  for the key you created.
  • Then navigate to  Settings, click on  Apps  →  View App Configurations  →  +App, choose Configuration Type = By Client ID, paste copied  Client ID  and click Submit.

Step 9: Create a test assignment

  • Open any course as a teacher, go to  Assignments  →  + Assignment , and in  Submission Type  choose  External Tool.  Enter the link https://plagiarismcheck.org/lti/launch in the  Enter  or find an external tool URL field.

Testing the integration

After registration, switch to a test course and create an assignment that uses PlagiarismCheck as its external tool. Submit a short sample document as a student, return as the instructor, and confirm that the originality report opens and the grade syncs back to the gradebook.

Troubleshooting

Tool stays Pending and never activates

Reopen the registration page in another tab and check that the URL you pasted into Canvas hasn’t expired. Registration URLs are single-use; generate a new one and repeat the registration step.

Originality reports don’t appear in the gradebook

Confirm that Assignment and Grade Services and Names and Roles Provisioning are enabled on the tool. In Canvas, verify the assignment was created with PlagiarismCheck as the submission type.

Students see an error when launching the tool

Ask the student to clear cookies for your LMS domain and retry. If the error persists, copy the error code from the launch screen and contact support@plagiarismcheck.org.
