For Facebook/Google SSO (single-sgin-on), the normal procedure is to create a separate FB developer app and get the key pairs & integrate with the application.
If white labeling is allowed as below:
client1.com points to client1.ourproduct.com
client2.com points to client2.ourproduct.com
client3.com points to client3.ourproduct.com
Is there any better approach to avoid creating FB developer apps for each customer/client and integrate with the application? I mean, is there any way to manage with a single developer app and manage with this esp when white labeling is allowed? Kindly suggest.
