Linkedin OAuth2 authorization code error

Question

I´m trying to connect via Linkedin Auth2 from a java web application:

1. Added my own app in linkedin.
2. Generate the authorization URL: https://www.linkedin.c

Answer 1

I too got bugged with this issue for long time. Please keep few things in mind which I did and eventually sorted it out.

1. Hit the api to get authorization code by using get request.
2. The authorization code has a life span of about 20 seconds, so its difficult to manually copy the code from the url and make a request for token access. You should do it pro-grammatically.
3. Make a post request for getting access token.
4. Most Important: Old linkedin applications that I had created was not working and giving the above error. Create a new linkedin application and try. Doing this worked for me.

I assume that all the other parameters like client_id, secret, redirect_uri are correct.

please try and let us know.

Thanks.
