unauthorized_scope_error in LinkedIn oAuth2 authentication

My little contribution in 2021.

It seems like Linkedin keeps changing the value for scopes.

On the Linkedin developer portal looking under OAuth 2.0 scopes section in the Auth tab, I found the values that finally worked for me.

PS: Make sure to enable Sign-in from the product Tab.

We have to enable "Sign In with LinkedIn" under the products tab, only then you can avail that scope (r_liteprofile and/or r_emailaddress) and services.

This goes for the review process(System takes max 60 mins to approve) and If your request has been approved, the relevant product will be moved to the "Added products" section.

This happened to me the other day but somehow I was able to get around the issue. The new Microsoft API docs for LinkedIn are up to date. The docs on LinkedIn Developers portal will soon be outdated:

Important update: All developers need to migrate to Version 2.0 of our APIs and OAuth 2.0 by March 1, 2019.

A few things to try:

• Register a new LinkedIn OAuth 2.0 developer application - newly registered applications have access to the new V2 API
• Try removing the r_liteprofile scope or revert back to r_basicprofile

Navigate to Products in the LinkedIn Developer Console and select Sign in with LinkedIn.

The verification process takes a few moments and then r_emailaddress and r_liteprofile should appear under your permissions.
