LinkedIn V2 api: Not enough permissions to access /me GET
This is a old question, but the solution is to use the scope r_liteProfile instead of r_basicprofile during the first step of authorization.
https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id=*****&redirect_uri=http://yourauthorizationserver&state=RandomString&scope=r_liteprofile
Then, use the value of the code parameter passed back from LinkedIn to http://yourauthorizationserver in the second step of authorization:
curl -X POST \
'https://www.linkedin.com/oauth/v2/accessToken?code=codeobtainedwiththefirstcall&grant_type=authorization_code&client_secret=*****&client_id=***&redirect_uri=yourredirecturi' \
Solution found here: Any queries to the api.linkedin.com/v2/ return "Not enough permissions to access ..."
The LinkedIn API has been largely closed off and is only available to approved LinkedIn developers. You can request authorisation here: https://business.linkedin.com/marketing-solutions/marketing-partners/become-a-partner/marketing-developer-program
