Thanks for your answer. I got it.

I think you should implement custom registration or login logic using FusionAuth's webhooks or API. For example, you can check the application context during login and prevent users from being registered or authenticated in an application they are not supposed to access.

Hello,
I am developing a Spring Boot REST API, this API exposes a "/verify" endpoint to validate the token and the access to a certain resource. In FusionAuth I have roles attached to my users. So is the a method to validate if the user has that role so i can let them pass?
