AyanB.04075 (Customer) asked a question.
We are developing one app (iOS & Android both) where we need to authenticate okta user in Xamarin.Forms. We've successfully able to redirect user to OKTA login screen and from there redirecting user to our custom app.
Now one requirement came up such as ,
- Check Okta user using email id ( this part we have done using OKTA Api)
- If user doesn't exist then navigate to OKTA user registration screen.
For 2nd part , we've enabled self-service registration and able to see Sign Up link but this is not satisfactory, what customer wants is to navigate to OKTA user registration screen from custom mobile app and after doing registration redirecting to custom app with successful authentication.
Please let me know if this can be done.

Self-Service Registration setting allows you to choose "Default Redirect" to Custom URL or User dashboard. Or you can embed custom link to your User Activation email if "Activation requirements" is mandatory in Self-Service Registration setting.
"Default Redirect" = After registration, users will be redirected to the app that sent them to the registration form. In the event that no app context is provided, they will be redirected to the location selected here.
