Is there any possiblity to connect registered user with organisation during sign up?


I want to approach a problem when the user signs up using auth0 with a particular domain and during registration, I need to connect the user domain from email with the particular organization which already was defined in the auth0 dashboard.

Is it possible somehow?

I would create auht0’s pre-registration hook to call Rails API and check which organization this domain belongs to. For example, I detected that organization no. 1 has domain:, so I should assign that user to organization no. 1.

But how should I modify the whole response to assign the user to the organization in auth0 while registering?

Please, help if you spot any hints here.

Thanks a lot,
