LinkedIn: Invalid redirect URI error

Question

I have created a sample call for LinkedIn authorization as follows:

https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=xxxxxxxx&client_secret=xxxxxxxx&redirect_uri=http://ws-100945:9080/ArtisWeb/index.html&state=9867998869&scope=r_basicprofile

but it is throwing an "Invalid redirect URI" error, I have double-checked the redirect_uri, it is correct one. Can anyone provide guidance?

Answer 1

There are 3 things to check:

1. the redirect_uri value should be url-encoded
2. double-check the URL also wrt. "http" vs."https" and port number
3. make sure you use the right client_id
