Issuance of Security Key

Product Type

The following table explains the details of "Product Type".

Product Type Description
Consumable Consumers can purchase this type of product anytime. Purchase history can be retrieved for 90 days.
Non-Consumable Consumers can purchase this type of product only once. Purchase history can be retrieved with no time restriction.
Limited Period Once this type of product is purchased, repurchase cannot be made during the time when the product effect set by CP lasts. Purchase history can be retrieved for 90 days. If “Limited Period” product type is chosen, the duration of time for the product effect to last can be entered in the units above minute. The duration time for the product effect to last is allowed for the maximum of 90 days.
Subscription DPI system processes automatic payment on a certain designated cycle.
Paid App For paid apps, when you register your app on DPI system you need to select it as paid app.
Dynamic Product In case that pater and Samsung agree on that products and prices will be managed by CMS of partner not Samsung’s DPI, partner should select “Dynamic Product” as a product type.
Even though all the information of actual products are on CMS, partner need to register a representative item on DPI once so that our system can display information on Samsung Smart TV App/Game store which is legally required and verify which server we need to call for certain products : CMS or DPI.

If Dynamic Product is chosen,
  • Partner does not register each products on DPI that partner sells in their app actually
  • Partner builds and operates its own CMS to manage products information including prices and to verify purchase requests
  • Additional requirements
    • Verification/No Verification:
      ‘Verification’ is a recommended option otherwise partner has to handle the verification process by themselves and take all the responsibility for all the error cases related to verification process.
      If ‘Verification’ is selected, ‘Verify URI’ is also required. This URI should serve the function of checking product information such as product itself, price and currency

    • Price Setting
      Price range information of products that you actually sells in your app is required by country/location. It is not used for actual payment for providing the app information on Samsung Smart TV App/Game store which is legally required.
      Thus, it has to be updated when the price range of your products is changed.

CMS (Content Management System) Product catalogue management server or system including price information. In this document, this word refers to the server for the type “dynamic product” that has all the information of products and handles verification with its own product catalogue. For reference, product information of other product types should be managed in DPI not 3rd party CMS.
DPI will be looking at CMS to pull necessary product information as needed. CMS will be the source of truth regarding content metadata, purchase history (which user bought which title at which resolution of PURCHASE/RENTAL, etc.) whereas DPI will be the source of truth of transactional data (i.e. transaction amount, tax amount). Both systems will be linked by "invoice ID" that is generated by DPI and passed over to CMS for every successful transaction.
