Which engines are supported?

Unity and Unreal both have documented SDKs. Anything else can integrate against the REST API directly, since the SDKs are wrappers over the same endpoints.

Does the in-game store share stock with my web store?

Yes. Products, offers and prices are defined once in the dashboard and both surfaces read from them, so there is no second catalogue to keep aligned.

How should my server know a purchase happened?

Through the payment webhook. Grant the entitlement server-side on that event rather than on a client callback, so a closed app or a manipulated client cannot cost you an item or hand one out free.

Can I sell subscriptions inside the game?

Yes. Recurring plans, trials and custom intervals are all supported, and the renewal, the retry on a failed card and the tax on each charge are handled for you.

What about mobile games and the app stores?

Selling through your own web store rather than in-app purchase is what avoids the platform commission — see the web store for mobile games page for how that flow works and where the rules sit.

Games · In-game store

Sell inside the game, without sending anyone to a browser.

The moment a player wants a currency pack is the moment they are playing. Unity and Unreal SDKs put the purchase in your own HUD, drawing on the same catalogue as your web store, so nothing has to be kept in sync by hand.

Selling at the moment of intent

001

Native

The purchase happens in your UI

The SDKs give you the catalogue and the payment flow, not a prefabricated shop screen. You draw the store to match your game, and the player never sees a layout that belongs to someone else.

002

Synced

One catalogue, two surfaces

Items, bundles, currency packs and subscriptions are defined once. The in-game store and the web store read the same list, so a price change or a new bundle does not need shipping twice.

003

Payments

Players pay how they normally pay

Cards and wallets, but also bank redirects, vouchers, buy-now-pay-later and local methods chosen for the player's country — plus crypto and stablecoins where that is what they hold.

004

Server-side

Entitlements from webhooks

Your server grants the item on the payment event rather than trusting the client. That is also what makes refunds, chargebacks and subscription lapses revoke access correctly.

The dashboard listing in-game items, bundles and virtual currency packs with their prices. — One catalogue behind both the in-game store and the web store.

Wiring the store into the game

01
Build the catalogue

Create the items, bundles and currency packs in the dashboard. This is the same catalogue your web store sells from.
02
Drop in the SDK

Add the Unity or Unreal package and authenticate with the API key from the dashboard. It fetches the catalogue and opens the payment flow.
03
Draw your own store screen

Lay the shop out in your game's own style. The SDK supplies data and checkout; the interface is yours.
04
Grant on the webhook

Your backend listens for the payment event and awards the item. Never fulfil from the client — that is the path an exploit takes.

What you can sell in-game

Virtual currency: Packs at whatever tiers you price them, with the bigger-pack discount handled as ordinary pricing.
Items and cosmetics: Individual assets, skins and unlocks, each with its own product record and its own delivery event.
Bundles and chests: Group several items into one purchasable offer without duplicating the underlying products.
Subscriptions and battle passes: Recurring plans with trials and custom intervals, renewing and lapsing without you writing the billing.
Unity and Unreal SDKs: Documented SDKs over the same REST API, so anything the SDK does you can also do server to server.
Tax on every purchase: We are the seller of record, so VAT, GST and sales tax on a currency pack sold anywhere are calculated and filed by us.
