Any queries to the api.linkedin.com/v2/ return “Not enough permissions to access …”

问题

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.

回答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!

回答2:

Use r_liteprofile instead of r_basicprofile during the first step of Authorization. This will solve your issue.

回答3:

API access changed and what you received with only 1 API call, now has to be rewritten to make multiple API calls

Before, using scope "r_basicprofile, r_emailaddress" you could get

• User basic info as name, location etc
• LinkedIn user profile URL
• Email
• Avatar image

Now you can use "r_basicprofile" that will get you user LinkedIn public URL only if you are in a partner program, and it is not easy to get in!

If you want to get access_token which you can use to get basic profile info + email, now you have to request it with a scope "r_liteprofile,r_emailaddress"

and use this 3 API calls to get all the details, unfortunately without Linkedin public URL (if anyone knows how to get this, please comment so I can modify the answer)

1. profile info - https://api.linkedin.com/v2/me
2. email - https://api.linkedin.com/v2/clientAwareMemberHandles?q=members&projection=(elements*(primary,type,handle~))
3. profile image - https://api.linkedin.com/v2/me?projection=(id,profilePicture(displayImage~:playableStreams))
4. public profile URL - not possible!
