The merchant of record for builders.

Integrate in an afternoon. Open a checkout and the currency, tax line and payment methods resolve from where the buyer is; subscriptions, proration and dunning come with it.

<script src="https://cdn.paddle.com/paddle/v2/paddle.js"></script>
<script>
  Paddle.Initialize({ token: "live_xxxxxxxxxxxx" });

  // Open a localized checkout: currency, tax and
  // payment methods resolve from the buyer's location.
  Paddle.Checkout.open({
    items: [{ priceId: "pri_01h...", quantity: 1 }],
    customer: { email: "ada@example.com" },
  });
</script>

Shape of a Paddle.js checkout; see developer.paddle.com for the exact API.

  • Paddle.js

    Embed an overlay or inline checkout. Preview localized prices with tax before the buyer commits.

  • Unified API and SDKs

    One API for products, prices, customers, subscriptions and transactions, with SDKs so you are not hand-rolling requests.

  • Webhooks

    Subscription and transaction events delivered to your backend; keep entitlements in sync without polling.

  • Docs built for agents

    Every docs page has an llms.txt and .md sibling, so your coding assistant reads the same source you do.

  • Paddle AI Toolkit

    Go from prompt to global selling: scaffold products, prices and checkout from a description.

  • Migration service

    Move subscribers from your current stack with help from Paddle. Nexus Mods migrated 100k+ subscribers.

Docs

Read the docs the way you read code.

Guides, API reference, SDKs and the Paddle.js reference live at developer.paddle.com, with an llms.txt and Markdown sibling for every page.
