I am receiving an HTTP 401 Unauthorized error when attempting to create a deep-link from my LMS

If you are attempting to create a deep link between Engageli and your LMS (e.g. Canvas, Moodle, etc) and are receiving an "HTTP 401 Unauthorized, MISSING_VALIDATION_COOKIE" error, then the issue is likely due to your browser having 3rd party cookies disabled. The full error you may encounter is seen below:

{
  "status": 401,
  "error": "Unauthorized",
  "details": {
    "description": "Error validating ltik or IdToken",
    "message": "MISSING_VALIDATION_COOKIE"}
}

To resolve this, please configure your browser to allow usage of third-party cookies.

Below are instructions on enabling third-party cookies in Chrome. You can also visit Google Chrome's article on this topic, found here. If you are using MS Edge or Brave, the instructions would be similar.

1. Within Chrome, click on the 3-dots menu at the top-right of the screen.
2. Select Settings.
3. In the Settings Search bar, type in cookies.
4. Look for the Third-party cookies section and select Allow third-party cookies.
   
5. You may need to restart your browser for the changes to take effect.
