I was able to get past invalid_callback error. Ref: Wso2 apiman: INVALID REQUEST, invalid_callback
However, I'm not able to generate tokens for api. Any workaround is much appreciated.
Caused by: javax.net.ssl.SSLException: hostname in certificate didn't match: localhost != dev.org

Any other changes to be made?
