@aghanim-sdk/checkout

Accept payments in your web game through the Aghanim checkout — no page leave, no server-side runtime.

📖 Full guide: docs.aghanim.com/checkout/javascript-sdk

Install

npm install @aghanim-sdk/checkout

Or via script tag (exposes window.Aghanim):

<script src="https://cdn.jsdelivr.net/npm/@aghanim-sdk/checkout/dist/aghanim-checkout.global.js"></script>

Quick start

import { Aghanim } from "@aghanim-sdk/checkout";

// Key from Dashboard → Integration → API keys.
const aghanim = Aghanim.init({ apiKey: "sdk_..." });

// As soon as your game knows who the player is;
// clearPlayerId() on sign-out.
aghanim.setPlayerId("player_1");

const order = await aghanim.orders.create({ items: [{ sku: "gems-100" }] });
const checkout = await aghanim.openCheckout(order);

checkout
  .onPaid(() => showSuccessUI())
  .onClosed(() => game.resume());

Orders created by this SDK are consumable. paid is a UX signal only: grant items from the item.add webhook, or drain the unconsumed list on boot, on resume, and after paid.

// Always grant first — consuming the same order twice fails.
for (const order of await aghanim.orders.unconsumedDetails()) {
  grantToPlayer(order.items);
  await aghanim.orders.consume(order.id);
}

Already creating orders server-side? Pass the opaque checkout_url straight through:

const checkout = await aghanim.openCheckout(checkoutUrlFromYourBackend);

Develop without a backend

const aghanim = Aghanim.init({
  apiKey: "sdk_mock",
  mock: { scenario: "instant_success" },
});

Scenarios (instant_success, open_external, three_ds, failure, poll_fallback, unconsumed) play scripted events through the real parsing pipeline. See examples/.
