Samsung IAP Instant Server Notification

The Samsung In-App Purchase (IAP) Instant Server Notification (ISN) is a service that provides notifications about user activities related to in-app items and subscriptions using the Samsung IAP service. The Samsung IAP ISN service does not provide notices for your Seller Portal activities such as content registration and distribution or item registration and price changes.

You must set up a server to receive the notifications, configure an IAP key to verify and authenticate the notifications, and configure an IAP item in your app with the URL used by your server to receive notifications. See Samsung IAP ISN Requirements for more information.
