[keycloak-user] Identity Provider / First Broker Login Flow Hooks

[Andreas Taube]

Hey together,

I would like to integrate with an external Identity Provider and I wonder
about the best way to hook into this process? As soon as the external IP
authorizes the user with a valid token I would like to do some internal
setup calls and link metadata to the user (attributes) being created by
Keycloak.

I know it is possible to extend Keycloak with custom IdentityProviderMapper
extensions but I would like to validate if they are also meant to execute
async http requests? If not, are there any other options better suited for
this use case?

Thanks for any feedback
