Step 2: Add the App in Canvas

Go to Admin > Settings > Apps.
Click View App Configurations.
Click + App.
Choose:
- Configuration Type: By Client ID
- Client ID: Use the numeric ID generated from your Developer Key
Click Submit.
Authorize the tool when prompted.

Step 3: Share Configuration Details with Lingco

Once you’ve completed the setup, please send the following information to [email protected] so we can enable LTI 1.3 for your institution on our side:

Client ID (from the Developer Key you just created)
Deployment ID (from the installed application under Admin > Settings > Apps)

These are required in order for Lingco to recognize your LMS instance and complete the integration.

Step 4: Test the Integration

After receiving confirmation from Lingco that we're ready for you to test, you can verify the integration is working as expected.

Open a course
Navigate to the Course Navigation menu
You should see Lingco LTI 1.3 as an available link
Clicking it will launch the tool using the LTI 1.3 flow
