Hi @balazs.bokanyi,
Thanks for reaching out to the Auth0 Community!
I understand that you’d like to bulk block users on your application.
Unfortunately, there isn’t an equivalent endpoint that could bulk block your users.
If you would like to block your users, you will need to use the Auth0 Management API Update a user endpoint to programmatically update those individuals to a blocked state.
As an alternative, you could consider using something like Auth0 Actions. If there is a specific condition which you know these users should be blocked, for example, a certain domain, IP address, or a list of email addresses, then you could have a Post-Login script waiting to block these users and deny them access.
Hoped this helps!
Thank you.
