Delegate Credentials validation to a Third Party endpoint



First of all, thank you for your time. I am new in Auth0 and I have a potential use case that I am not sure if it is possible to implement in Auth0.

I would like to use the Auth0 login page and pass the username/password (credentials) to a 3rd party REST endpoint for validation. This endpoint performs the validation and should return successful/unsuccessful authentication to Auth0.

Is that possible?

Client -> cicks login -> redirected to Auth0 website -> Types credentials -> Auth0 calls my endpoint with the credentials -> Auth0 receives response (200 or 401).

Thank you!
