A mobile game web store is a website where players buy game currency, items or packs for their existing game account. A complete store connects four things: player identity, a product catalogue, checkout and server-side delivery. The design makes it recognizable; the integration makes the purchase work.
Create your store free: paste your App Store or Google Play link and Appside drafts a store in your game's look. You can also try the live demo or follow the developer quickstart to connect an existing game.
From your app to a delivered purchase
- Identify the player. Your backend issues a short-lived player token. The store opens for the correct account without asking the player to create another identity.
- Show the right products. Packs, prices, bonuses and currency names come from the catalogue you review and publish.
- Complete checkout. The player selects a pack and completes the payment flow. A browser success screen tells the player what happened.
- Deliver on the backend. Your server verifies the signed order event, records the order ID and grants the purchased items once. The game can then refresh its balance.
Keep the browser and fulfillment responsibilities separate. Closing a browser must not lose a purchase; receiving a repeated event must not grant a second pack. The webhook guide explains the delivery contract, while player tokens cover account identity. Run the standalone webhook proof to check signed delivery, duplicate protection and refunds locally.
Start with the game's visual language
A familiar store uses the same world as the app: recognizable currency icons, pack artwork, names, color hierarchy and tone. A player should be able to answer “Is this my game's store?” before reading the footer.
Appside's builder starts with your app and screenshots to create a visual draft. You review that draft and supply the product details. Screenshots can show what a pack looks like; they cannot establish its authoritative price, eligibility or delivery rules.
Before publishing, check the smallest phone layout, long product names, localized prices, empty states and the return-to-game action. Give players a clear account indicator so they know which account will receive the purchase.
What your team supplies
| Input | Why it matters |
|---|---|
| App link, icon and screenshots | Establish the store's visual identity |
| Product IDs, prices and grant amounts | Keep the displayed offer aligned with fulfillment |
| Player identity integration | Associate each order with the right account |
| Signed webhook handler | Verify delivery and prevent duplicate grants |
| An Appside SDK for your platform | Open the store from the game and handle the return. Download Web, Node, Python, Android, iOS, Flutter, React Native or Unity |
| Return link and support route | Help players resume the game and resolve problems |
The fastest route to a working store is to reduce the work your team repeats. Reusing your existing player accounts and item-granting code matters as much as generating the first design. A fast draft and a production launch are separate milestones: payment activation and operational readiness still need to be completed.
Calculate costs using explicit assumptions
Appside's published rate, checked October 25, 2026, is 3.9% per successful payment, with no setup fee, subscription or minimum. See the pricing comparison.
For an illustrative $10,000 of successful web payments, a 3.9% percentage fee is $390, leaving $9,610 before other costs. This calculation excludes taxes, refunds, chargebacks, foreign exchange, promotions, support and integration work. It is not a payout quote or a forecast of incremental revenue.
Use the fee calculator with your actual comparison rate and volume. Keep the revenue base consistent: shifting existing purchases and attracting additional purchases are different scenarios. Do not assume every player moves to the web store or that a universal app-store rate applies.
Walk through the purchase before launch
Use the interactive demo to inspect the app-to-store journey, choose a currency pack, complete the demonstrated checkout and check the balance in the game. The testing guide explains the environment, payment status and test cases.
For your integration, record the starting player balance, pack grant amount and order ID. After delivery, verify that the balance increased by exactly the grant amount. Reprocess the same event and check that the balance stays unchanged. Then check an invalid signature and confirm it cannot grant items. These checks demonstrate the integration, rather than only the checkout's appearance.
A practical launch checklist
- Confirm that the store, receipt and support route identify your game and business clearly.
- Review every product ID, price, grant amount and promotion in the published catalogue.
- Verify signed player identity and signed backend delivery; keep secrets off the client.
- Exercise successful, failed and repeated delivery, plus the refund handling your game requires.
- Review current platform, region and payment-provider requirements for your distribution model. Start with the sourced iOS web-store linking guide and confirm the rules applicable to your release.
- Confirm payment activation, monitoring and customer support before accepting real purchases.
Build the store, then connect the game
Create your store free, try the live demo, follow the three-step integration, or give your coding agent access to the public MCP documentation server. To compare approaches, use the web-store platform comparisons.
