Hi nerds!

i'm studying Keycloak and how use they.

i have ever generated a token, but how ask to keycloak if that token is valid?

where i work, have many many systems and i cant change the forms login and use .ftl ....

The unique way i found is use REST in  the action form... but, i have two problems:

1 - after retrieve a token , how keycloak redirect de system to other page?

2 - how (or there are) a REST URI that i can ask to keycloak check if that token is valid?

i had dispensing many hours search how can i use keycloak without impact other systems..... ideas?

thank you so much

sorry for my bad english rsrs
