LTI 1.1 Setup Guide – Canvas Integration

Overview

This guide walks through the steps to re-install the Meazure Learning (ProctorU) LTI 1.1 tool in Canvas. Your Consumer Key and Shared Secret will be provided directly by Meazure Learning.

If you're a canvas administrator and need to re-establish your integration, please contact canvasreconfiguration@meazurelearning.com and we'll provide an updated key/secret. 

⚠️ Important: Full Reinstall Required

The existing LTI 1.1 integration in Canvas must be removed and re-added using the credentials provided by Meazure Learning. New credentials will not work against an existing tool record - Canvas stores the secret on the tool at the time of installation.

Step 1: Remove the Existing LTI 1.1 Integration

The existing tool must be removed and reinstalled rather than edited in place - new credentials only work against a freshly-installed tool in Canvas.

📋 Before you delete: If the existing LTI 1.1 tool has any custom placements, custom fields, or a non-default name, capture a screenshot of the configuration so you can recreate those settings in Step 2.

1. From the Canvas admin account, go to Admin → Settings → Apps tab
2. Click View App Configuration
3. Locate the existing ProctorU tool in the list
4. Click the gear icon on the right of that row, then choose Delete
5. Confirm the deletion

⚠️ Important: Deleting the tool does not delete exam history, courses, or any data on the Meazure Learning side. It only removes Canvas's stored copy of the launch URL and Shared Secret.

Step 2: Create the New LTI Tool

In Canvas, go to Admin → Settings → Apps tab, then click View App Configuration. On the External Apps page, click the + App button in the upper right.

📌 If Canvas shows a redesigned Apps page (with Discover / Manage / Monitor tabs): choose "Install a New App", select LTI version 1.1, then click the legacy apps page link. LTI 1.1 installs are completed through the legacy External Apps view in all Canvas versions.

An Add App dialog will appear. Fill out the following:

1. Click Submit
2. Confirm the tool appears in the External Apps list
3. Click the gear icon next to the new tool's row, then choose Placements to verify Course Navigation, Account Navigation, etc. loaded from the XML config
4. Proceed to Step 3 to test the integration

📌 Note on placements: The Config URL publishes an XML configuration that automatically sets up Canvas placements. This will automatically make the tool visible in all courses.

Optional: Disable the Tool in Courses by Default

If you want the ProctorU tool to be hidden in Course Navigation by default - requiring instructors or admins to manually enable it per course - configure the tool using the Paste XML option instead of By URL.

In the Add App dialog, set Configuration Type to Paste XML, enter the Consumer Key and Shared Secret as provided by Meazure Learning, and paste the following XML into the XML Configuration field:

<?xml version="1.0" encoding="UTF-8"?>

⚠️ Note: With this configuration, the tool will not appear in Course Navigation until an instructor or Canvas admin explicitly enables it under Course Settings → Navigation. This is useful when the tool should only be active in select courses rather than institution-wide.

Step 3: Test!

✅ Setup is complete! You should now be able to click the ProctorU tool from a course and log in successfully.

Please contact canvasreconfiguration@meazurelearning.com with any questions or concerns.

Troubleshooting

"Invalid Signature" or "Authorization Required" When Launching the Tool

• Most common cause: the Shared Secret was pasted with a leading or trailing space. Copy directly from the credential source rather than selecting manually.
• Confirm the Consumer Key matches exactly - it is case-sensitive.
• Confirm the old tool was fully removed in Step 1 before installing the new one - having both old and new tools in the External Apps list can route launches to the wrong tool.

Can't Find the Tool in Canvas After Install

• Go to Admin → Settings → Apps → View App Configuration and confirm the tool appears in the list.
• If it's listed but not appearing in Course Navigation, go to a course → Settings → Navigation and confirm ProctorU is in the active navigation list (drag it up from the hidden section if needed).

XML Config URL Returns an Error During Install

• Confirm the Config URL was entered exactly as provided.

Tried to Update the Tool Name and It Still Shows "ProctorU"

• When pasting XML in Canvas, it may appear to duplicate itself - find the closing </cartridge_basiclti_link> tag and delete everything after it, or leave all text and edit the name in both entries to match your desired display name
