Linkedin OAuth unauthorized client error

Question

Getting this as the response:

{"error":"unauthorized_client","error_description":"the client is not authorized"} 

In the final step of OAuth 2.0 to use LinkedIn APIs. Couldn't get any material regarding this, so could anyone please help me with this ?

I am calling it as POST method too.

Answer 1

I was getting this error when I was not passing the correct value in the client_secret value in the POST to retrieve the access_token. Once I passed in the correct value (BTW, linked calls this parameter as Secret Key on the developer console), this started working for me.
