TV in-app purchases: Samsung Checkout vs Paymentwall

The options side by side

Samsung Checkout and the DPI portal

Samsung Checkout is a complete TV payment system: a three-step purchase flow on the TV, products managed in the DPI portal, settlement and payout run by Samsung, and a service matrix covering 120 countries.

Product types

• Consumable: coins, lives, hints.
• Non-Consumable: a level pack, "remove ads".
• Limited Period: access for a set time.
• Subscription: with upgrade and downgrade tiers, and free trials per product group (once per account and/or device).
• Paid App.
• Dynamic Product: product data managed in your own system instead of the DPI portal.

The access question

The Billing API is a public privilege (available since Tizen 2.4; cancelSubscription since 4.0). But the purchase flow uses the SSO API's getLoginUid, which needs the partner-level sso.partner privilege, and the Flutter in_app_purchase_tizen plugin documentation says apps must be signed with a partner-level certificate. Add that Public Sellers can launch only in the US, and Samsung Checkout is realistically a Partner Seller feature. Buyers need a Samsung account. Samsung doesn't publish its revenue share; check your Seller Office terms.

LG webOS: billing discontinued, Paymentwall recommended

LG's in-app purchase guide says: "The LG Billing Service for In-App Purchase is no longer provided." LG recommends Paymentwall and may ask for a separate contract if you use another third-party billing solution.

In Seller Lounge the billing options are webOS Pay, third-party billing, or both. webOS Pay is tied to the user's LG account; how widely it is open to third-party developers isn't clear from public documents. When developers asked about Stripe and PayPal in August 2026, LG pointed them to the provider and to Seller Lounge 1:1 Q&A. LG publishes no revenue-share figures.

Whale TV and Titan OS

Neither publishes a payment or subscription API for third-party apps. Whale TV's commercial terms are set in its distribution agreement; Titan OS handles commercial questions through its business development team. If you need payments there, the usual route is your own account system with payment on the phone.

Remote-friendly checkout

Typing a card number with a D-pad is where TV purchases die. Whatever the payment system:

• Use the platform flow where you have it. A stored account payment (Samsung Checkout) is a few OK presses.
• Otherwise hand off to the phone. Show a QR code that opens a checkout page tied to the TV session, and unlock the item when the server confirms payment.
• Few, clear products. Two or three options with the price on the button.
• Confirm on screen and restore purchases on reinstall.

Hybrid: in-app purchases plus rewarded ads

Most players in a free TV game won't buy anything. Ads earn from all of them; purchases earn from a few. The two work together:

• Sell "remove ads" as a non-consumable, and keep rewarded ads available for players who want them.
• Give the same item two prices: coins for a purchase, or a smaller amount for a rewarded ad.
• Use ads where purchases aren't possible: on Whale TV and Titan OS, or as a Public Seller outside the US.

if (!store.owns("remove_ads")) {
  await SofAds.showInterstitial({ placement: "level_break" });
}

// Rewarded stays available to everyone, including buyers
SofAds.showRewarded({ placement: "bonus_coins", onReward: () => wallet.add(50) });
