I am unable to get the LinkedIn api's access token.
I followed the documentation and proceed accordingly but unfortunately it was all unsuccessful attempts for which I really don't know the exact reason as I have followed the correct steps as per the official documents and several other links available on the internet.
To my knowledge as per the document, It has two ways of generating the access tokens and they are :-
1) Two Legged
2) Three Legged
I tried both of them using postman but it is giving the same errors all the time, which I will share as attachments.
Any help would be appreciated.
