“Customer extension” is where your customers can access information about promotions, redeem points, and share your brand on other platforms with their friends.
Interacting with the customer extension is easy! Just go to the online store's website and click on the 'Reward' button on the screen. You can customize the display area and the name of the button in the “Branding/Launcher” section.
"The interface and functions within the customer extension will differ slightly for users who haven't logged in (Visitors) and those who have logged in (Members). For more details, please visit the sections below.”
