From Samsung

Dear seller,
This is the Seller Office team.
Thank you for your continued support of the Samsung Apps Seller Office.We are proud to announce that the development of In-App Purchase 2.0 is complete, and ready for our customers to use, and ask you to read the information below.
 In-App Purchase 2.0 launch date scheduled : June 20, 2013 (The schedule may change subject to any unforeseen circumstances.)
* You can download information about In-App Purchase 2.0 from Samsung Developers at
 Introduction of major features in In-App Purchase 2.0


Support for Various Types of Items
In-App Purchase 2.0 and higher versions provide three types of items for users to choose from during development: consumable, non-consumable, and subscription. You can select the item type in the Seller Office; please note that the item type cannot be changed once it has been selected.
Also, subscription items are included as non-consumable items.


New Recovery Function for Account-based Items
Your history of purchased items will now be based on your account, rather than IMEI. Non-consumable items, which can only be purchased if you have signed in with your user account at least once before, can be recovered if the purchase history for the account can be verified after the application is re-installed.


Single Sign-On for Samsung Accounts
When you sign in to In-App Purchase with your Samsung account, you are also signed in to all of Samsung’s other content services.


Support of Overseas (American) Credit Cards
Now Sellers can sell their items in the world’s largest market, the U.S.A. Users in the U.S.A. can use their American credit card to purchase items in applications that have In-App Purchase 2.0; more payment options will be available soon.


Overall Improvements to the UX
In-App Purchase 2.0 offers an improved UX (User eXperience) from the latest version of Samsung Apps.


Support of Stand-Alone APK
The conventional library type has been replaced by Stand-alone APK and users can expect the following advantages:
Minimization of APK File Volume in Applications
In the past, the volume of applications increased because of In-App Purchase resources when an application was developed with the library type, but the problem no longer exists with Stand-alone APK.
Easy Application Maintenance
The latest version of In-App Purchase can be maintained without additional application updates.
Because APK can be updated automatically when In-App Purchase APK functions are added or modified, applications do not have to be distributed again every time the library is modified.
Development of In-App Purchase linkage within applications
Users do not have to download the library from the developer site (SAMSUNG Developers); In-App Purchase APK files are automatically installed in the device when the user uses Samsung Apps.
Stand-alone APK is provided to decrease the time taken to implement In-App Purchase.
[Note regarding item payment certification for Samsung In-App Purchase]
When accessing the certification server for item payment certification, use the verifyUrl value relayed from PurchaseTicket. If you hard-code the verifyUrl value or arbitrarily try a URL validation check, a problem may occur in the final certification phase.
※ If the final certification is unsuccessful because of a failure to use the correct verifyUrl value, the user may not receive the item even though the payment has been successfully processed. This is a very sensitive issue which may cause customer complaints, so any applications with this problem may be suspended by Samsung, with the Seller being informed of the details. Should your application be suspended, you must first make the appropriate modifications, and then register the application again.
