We don't have a way to redirect to a URL for social login, but we do have a way to configure a specific success page, which could instruct users to go to a particular page if you'd like. You can do this by going to Configure> Open the Network Policy> Open the SSID> Enable Captive Web Portal (CWP)> Choose the Cloud CWP options> Choose Social Login> Add> Toggle Customize on> Import an HTML file for the success page> Select this file in the Success Page drop down.
