需要来自app密钥和密码的令牌以获取linkedin中的帖子详细信息

I am building a website where user share status on his linkedin profile and it work well and I store the updated key comming in response.

I want to get like count on the status post on linked with stored updated id.

I used likes($updateId) function of Linkedin API but getting error in response.

Error:
