yes we can , hit API 3 times

so you mean , every time on registration form info would go to 3 applications and also to Fusionauth?

yes we can , hit API 3 times

@dan said in Registering a user to other applications during registration:

You are right, yes I want if a person register at any of appA.com appB.com or appC.com they should be able to login.

Nothing has been implemented yet. Currently all three applications have their own sign-in/Reg flow where we save each user to respective app db. with SSO wish to give cross application access depending on type of user.

We wish to use own registration form.

Hi Den,
we have 3 diffrent domains and trying to impliment fusionauth, but we are not understanding how registrations will work?
and everywhere i am trying to find out with SSO, it talks about process after userlogin , but nowhere i could see anything about registrations?
Can you throw some light on this ? where will my users register for all 3 applications sitting on 3 different domains and how does fusionauth authenticate if it will not register?
I thought fusionauth will handle both processes, from same page.

My case is Thant I have 3 different application that i want to bring under 1 umbrella , out of 3 one is developed via MEAN stack and other 2 are PHP applications. Currently all 3 of them uses its own user login and registration system. I wish to have single sign on (like google uses for all apps) so user with one sign in can have access to all 3.

So my question is
1- can it be done with FusionAuth ?
2. if yes, in that case what about the existing login/reg flow already exist in 3 applications, do i have to get rid of them completely and than add fusionauth or let them sit as it is and fusionauth will provide another layer top of it?

And what will be best way connecting these applications using OIDC or SAML (i am not sure whats diffrence)?

Thanks

And What if all applications are pre-developed and you can still integrate with Fusionauth SSO? without disturbing their own sign-in processes?
