Direct card checkout in a browser game means handling cardholder data or embedding a processor’s hosted form, meeting PCI DSS requirements, doing server-side order/receipt validation, and passing browser security checks (HTTPS, CSP). Most web game developers avoid this by routing purchases through a platform’s existing payment system instead.

| Fact | Value | Source |
|---|---|---|
| Card data must never touch your own servers | use hosted checkout form | wiki.playgama.com |
| PCI DSS compliance scope | even with hosted forms | wiki.playgama.com |
| Purchases need server-side receipt validation | prevents client-side fraud |
Building your own credit card checkout inside a browser game is technically possible but heavy for most teams. The core barriers:
- You cannot let raw card numbers touch your own client or server code without taking on PCI DSS compliance scope.
- You need a processor (Stripe, Braintree, Adyen, etc.) whose hosted iframe or redirect form collects the card data instead.
- You need a server endpoint to create orders, verify webhooks/receipts, and grant in-game currency only after the processor confirms payment – never on a client-side callback alone, since that is trivially spoofed.
- The page needs HTTPS, a compatible Content-Security-Policy to allow the processor’s iframe or script, and handling for 3D Secure redirect flows without losing game state.
Because of this, most web game developers skip building card checkout entirely and route purchases through a platform that already has payment rails. If you publish the game through Playgama using the Bridge SDK, in-game purchases (consumable and permanent) are supported on platforms that offer them (currently Playgama, Yandex, MSN, Samsung and Facebook) and are processed by those platforms; the developer’s share is set in the Developer Terms.

Can I just embed a Stripe form directly in my game’s HTML?
Yes, using Stripe’s hosted Checkout or Elements keeps card data off your servers, but you still need a backend to create sessions and verify payment before granting rewards.
Why can’t the client just tell the game the payment succeeded?
Client-side confirmation can be faked by editing JavaScript or replaying requests; rewards must be granted only after a server verifies the processor’s payment confirmation or webhook.
