Payment flow with Dynamic Product

In case that partner already has CMS server which manage products and price, and it is required to change the product information frequently, partner and Samsung can discuss to use dynamic product when they integrate Samsung Checkout.

And once they agree on that products and prices will be managed by CMS of partner not by Samsung’s DPI, partner need to register a representative item on DPI so that Samsung Checkout system can display information on Samsung Smart TV App/Game store which is legally required.

Partner does not need to register each products on DPI that they sells in their app, however,
They should builds and operates its own CMS to manage products information including prices and provide rest API for verification of purchase requests.

The following figure shows data flow of initialize stage in payment process with dynamic product.

Additional requirement for DPI

As model require Partner CMS to manage product information, there is additional requirement that partner need to do for DPI settings.

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 in sequence of initialization during payment process.
Price Setting

Price range information of products that you actually sells in your app is required by country. It is not used for actual payment for providing the app information on Samsung Smart TV App/Game store which is legally required.
