Hi Ori,
AFAIK at the moment there are no extension points to hook into the
token refresh process. I'd suggest the following:
- if your JS frontend allows for alternate OIDC URLs, you could
implement a custom token endpoint by extending TokenEndpoint and adding
your logic;
- you could also try creating custom protocol mapper. Start with
creating a dummy one and test if it is indeed invoked upon token
refresh.
Cheers,

Hi,
I'm looking for a way to customize the OIDC token endpoint:
In OICD code flow, when getting a new access token using a refresh
token, I want to call an external system and update a user attribute,
such that the attribute value will be mapped to an attribute of the
returned JWT access token.
I think the relevant source code is here, but I didn't see a way to
customize it using an SPI:
https://github.com/keycloak/keycloak/blob/master/services/src/main/ja
va/org/keycloak/protocol/oidc/endpoints/TokenEndpoint.java
The reason I need it is because we are working with an external
identity provider, which returns an access token to us which is valid
for only 15 minutes.
The external access token is mapped to our JWT once the user logs in
(we customized the authentication flow).
Now I need a way that my JWT will always contain a valid external
access token.
Therefore, I thought we can fetch a new external access token every
time we refresh our JWT.
Or is there a better way to accomplish that?
Thanks,
Ori Doolman
