Any queries to the api.linkedin.com/v2/ return "Not enough permissions to access ..."

Question

1. I got the Access Token (with scope: r_basicprofile rw_company_admin w_share) using the Client ID, Client Secret at following URLs:
   • https://www.linkedin.com/oauth/v2/authorization
   • https://www.linkedin.com/oauth/v2/accessToken

2. Make request to the https://api.linkedin.com/v2/me endpoint

   curl -H "Authorization: Bearer ACCESS_TOKEN"
       -H "Accept: application/json"
       -H "Content-Type: application/json"
       -H "X-Restli-Protocol-Version: 2.0.0" https://api.linkedin.com/v2/me
   

3. Get response:

   {
       "serviceErrorCode": 100,
       "message": "Not enough permissions to access /me GET ",
       "status": 403
   }
   

Similar erroneous responses are returned to any requests for https://api.linkedin.com/v2/

In official documentation there is difference requirements to headers:

• X-Rest**l**i-Protocol-Version
• X-Rest**L**i-Protocol-Version

But I tried both, and nothing worked.

Requests to the https://api.linkedin.com/v1/ (using the same token) successfully return data.

Please, tell me what I'm doing wrong.

Answer 1

You need to request permissions from LinkedIn.

Now all requests to api.linkedin.com/v2/ successfully pass to me!

We received permissions (r_ad_campaigns and rw_organization) after request offer by address https://business.linkedin.com/marketing-solutions/marketing-partners/become-a-partner/marketing-developer-program

Leave a request at the address below and LinkedIn will answer you.

Good luck!
