Login with Kakao

Hi,
I am trying to create a login with Kakao functionality on my Magento 2 web portal. I have created an application for the same on Kakao developers. I have my Native app key and REST API key. However, the login is not working. It’s giving me error like “the Login Application was not configured correctly.”

Hi,
Could you show us the web page that giving you an error? The error message seems a bit unfamiliar to me.
We need to know further information to help you with implementing the Kakao Login.
