[keycloak-user] Adding information from a 3rd party service into JWT token

[Michael Isvy]

hi,
thanks a lot for the hard work on Keycloak! I've been using it for a few
days and have been quite impressed by the UI, features and level of
documentation.

I have a custom requirement. When users authenticate, in case of successful
authentication,I need to call a 3rd party API, collect additional
information and place it into my JWT token.

I am in the process of doing it by coding my own Mapper (extending
AbstractOIDCProtocolMapper). I was wondering if this is the correct way to
do it or if there is a simpler way to achieve my goal.

Regards,
Michael.
