### API Response

All methods above return the same response structure:

```json theme={null}
{
  "session_id": "cks_Gi6KGJ2zFJo9rq9Ukifwa",
  "checkout_url": "https://test.checkout.dodopayments.com/session/cks_Gi6KGJ2zFJo9rq9Ukifwa"
}
```

<Steps>
  <Step title="Get the checkout URL">
    Extract the `checkout_url` from the API response.
  </Step>

  <Step title="Redirect your customer">
    Direct your customer to the checkout URL to complete their purchase.

    ```javascript theme={null}
    // Redirect immediately
    window.location.href = session.checkout_url;

    // Or open in new window
    window.open(session.checkout_url, '_blank');
    ```

    <Tip>
      **Alternative Integration Options**: Instead of redirecting, you can embed the checkout directly in your page using [Overlay Checkout](/developer-resources/overlay-checkout) (modal overlay) or [Inline Checkout](/developer-resources/inline-checkout) (fully embedded). Both options use the same checkout session URL.
    </Tip>
  </Step>

  <Step title="Handle the return">
    After payment, customers are redirected to your `return_url` with query parameters including payment/subscription ID, status, customer email, and any license keys. See the [`return_url` parameter docs](#request-body) for the full list.
  </Step>
</Steps>

## Request Body

<CardGroup cols={2}>
  <Card title="Required Fields" icon="asterisk">
    Essential fields needed for every checkout session
  </Card>

  <Card title="Optional Fields" icon="gear">
    Additional configuration to customize your checkout experience
  </Card>
</CardGroup>

### Required Fields

<ParamField body="product_cart" type="array" required>
  Array of products to include in the checkout session. Each product must have a valid `product_id` from your Dodo Payments dashboard.

  <Tip>
    **Mixed Checkout**: You can combine one-time payment products and subscription products in the same checkout session. This enables powerful use cases like setup fees with subscriptions, hardware bundles with SaaS, and more.
  </Tip>

  <Expandable title="Product Cart Item Properties">
    <ParamField body="product_id" type="string" required>
      The unique identifier of the product from your Dodo Payments dashboard.

      **Example:** `"prod_123abc456def"`
    </ParamField>

    <ParamField body="quantity" type="integer" required>
      Quantity of the product.

      **Example:** `1` for single item, `3` for multiple quantities
    </ParamField>

    <ParamField body="addons" type="array">
      Array of addons to attach to the product. Only valid if the product is a subscription.

      <Expandable title="Addon item properties">
        <ParamField body="addon_id" type="string" required />

        <ParamField body="quantity" type="integer" required />
      </Expandable>
    </ParamField>

    <ParamField body="amount" type="integer">
      Amount the customer pays if pay\_what\_you\_want is enabled. If disabled, this field will be ignored.

      **Format**: Represented in the lowest denomination of the currency (e.g., cents for USD). For example, to charge \$1.00, pass `100`.
    </ParamField>

    <ParamField body="credit_entitlements" type="array">
      Per-checkout-session overrides for credit entitlements already attached to this product. Use this to grant a different number of credits for this single session — e.g., a promotional bundle that grants 1,000 API credits instead of the product-default 500 — without creating a separate product.

      <Info>
        Each `credit_entitlement_id` must already be attached to the product. This field overrides only the `credits_amount` granted when this session is fulfilled; product-level credit entitlement settings (expiration, rollover, etc.) still apply.
      </Info>

      <Expandable title="Credit entitlement override properties">
        <ParamField body="credit_entitlement_id" type="string" required>
          ID of the credit entitlement to override. Must already be attached to the product.
        </ParamField>

        <ParamField body="credits_amount" type="string" required>
          Number of credits to grant for this checkout session, overriding the product-level `credits_amount`. Must be greater than zero.
        </ParamField>
      </Expandable>
    </ParamField>
  </Expandable>
</ParamField>

<Tip>
  **Find Your Product IDs**: You can find product IDs in your Dodo Payments dashboard under Products → View Details, or by using the [List Products API](/api-reference/products/get-products).

      | `license_key`     | `string` | Present if the product has license keys enabled. Comma-separated if multiple keys |

        Set a `cancel_url` to give customers a clear way to return to your site without completing the purchase. This improves the checkout experience and reduces friction.
      </Tip>
    </ParamField>

    <ParamField body="confirm" type="boolean" default="false">
      If true, finalizes all session details immediately. API will throw an error if required data is missing.
    </ParamField>

    <ParamField body="discount_codes" type="array">
      Apply one or more stacked discount codes to the checkout session. Codes are applied **in array order** (the first code reduces the base price, the second reduces the already-discounted price, and so on), up to a maximum of **20** codes per session.

      ```typescript theme={null}
      discount_codes: ['WELCOME10', 'BLACKFRIDAY20']
      ```

      <Info>
        The singular `discount_code` field below is **deprecated** but still fully supported — existing integrations continue to work without changes. It cannot be combined with `discount_codes` in the same request. Migrate to `discount_codes` when convenient to take advantage of stacking.
      </Info>
    </ParamField>

    <ParamField body="discount_code" type="string" deprecated>
      **Deprecated** — prefer `discount_codes` for new integrations. This field still works for backward compatibility, but cannot be combined with `discount_codes` in the same request.
    </ParamField>

    <ParamField body="metadata" type="object">
      Custom key-value pairs to store additional information about the session.
    </ParamField>

    <ParamField body="force_3ds" type="boolean">
      Override merchant default 3DS behaviour for this session.
    </ParamField>

    <ParamField body="minimal_address" type="boolean" default="false">
      Enable minimal address collection mode. When enabled, the checkout only collects:

      * **Country**: Always required for tax determination
      * **ZIP/Postal code**: Only in regions where it's necessary for sales tax, VAT, or GST calculation

      This significantly reduces checkout friction by eliminating unnecessary form fields.

      <Tip>
        Enable minimal address for faster checkout completion. Full address collection remains available for businesses that require complete billing details.

    {
      product_id: 'prod_ebook_guide',
      quantity: 1
    }
  ],
  customer: {
    email: 'customer@example.com',
    name: 'John Doe'
  },
  return_url: 'https://yoursite.com/success'
});
```

### 2. Keranjang Multi-Produk

      quantity: 2
    },
    {
      product_id: 'prod_warranty',
      quantity: 1
    }
  ],
  customer: {
    email: 'customer@example.com',
    name: 'John Doe',
    phone_number: '+1234567890'
  },

  return_url: 'https://saas-app.com/onboarding',
  metadata: {
    plan_type: 'professional',
    referral_source: 'google_ads'
  }
});
```

### 4. Checkout yang Dikonfirmasi Sebelumnya

<Note>
  Ketika `confirm` diatur ke `true`, pelanggan akan langsung dibawa ke halaman checkout, melewati langkah konfirmasi.

    {
      product_id: 'prod_luxury_watch',

  return_url: 'https://luxury-store.com/purchase-confirmation',
  metadata: {
    product_category: 'luxury',
    price_range: 'high_value'
  }
});
```

### 11. Menggunakan Metode Pembayaran yang Ada untuk Checkout Instan

Gunakan metode pembayaran yang disimpan pelanggan untuk membuat sesi checkout yang diproses segera, melewati pengumpulan metode pembayaran:

```javascript expandable theme={null}
const session = await client.checkoutSessions.create({
  product_cart: [
    {
      product_id: 'prod_premium_plan',
      quantity: 1
    }
  ],
  customer: {
    customer_id: 'cus_123'  // Required when using payment_method_id
  },
  payment_method_id: 'pm_abc123',  // Use customer's saved payment method
  confirm: true,  // Required when using payment_method_id
  return_url: 'https://yourapp.com/success'
});
```

<Warning>
  Ketika menggunakan `payment_method_id`, `confirm` harus diatur ke `true` dan `customer_id` yang sudah ada harus disediakan. Metode pembayaran akan divalidasi untuk kelayakan dengan mata uang pembayaran.
</Warning>

<Info>
  Metode pembayaran harus menjadi milik pelanggan dan kompatibel dengan mata uang pembayaran. Ini memungkinkan pembelian satu klik untuk pelanggan yang kembali.
</Info>

### 12. Tautan Pendek untuk URL Pembayaran yang Lebih Bersih

Buat tautan pembayaran pendek yang dapat dibagikan dengan slug kustom:

```javascript expandable theme={null}
const session = await client.checkoutSessions.create({
  product_cart: [
    {
      product_id: 'prod_monthly_subscription',
      quantity: 1
    }
  ],
  short_link: true,  // Generate a shortened payment link
  return_url: 'https://yourapp.com/success',
  customer: {
    email: 'customer@example.com',
    name: 'John Doe'
  }
});

// The checkout_url will be a shortened, cleaner link
console.log(session.checkout_url);  // e.g., https://checkout.dodopayments.com/buy/abc123
```

<Tip>
  Tautan pendek sangat cocok untuk berbagi melalui SMS, email, atau media sosial. Mereka lebih mudah diingat dan membangun kepercayaan pelanggan lebih baik daripada URL panjang.
</Tip>

### 13. Lewati Halaman Sukses Pembayaran dengan Pengalihan Langsung

Alihkan pelanggan segera setelah penyelesaian pembayaran, melewati halaman sukses default:

```javascript expandable theme={null}
const session = await client.checkoutSessions.create({
  product_cart: [
    {
      product_id: 'prod_digital_product',
      quantity: 1
    }
  ],
  feature_flags: {
    redirect_immediately: true  // Skip success page, redirect immediately
  },
  return_url: 'https://yourapp.com/success',
  customer: {
    email: 'customer@example.com',
    name: 'Jane Smith'
  }
});
```

<Tip>
  Gunakan `redirect_immediately: true` saat Anda memiliki halaman sukses kustom yang memberikan pengalaman pengguna lebih baik daripada halaman sukses pembayaran default. Ini sangat berguna untuk aplikasi seluler dan alur checkout tertanam.
</Tip>

<Note>
  Saat `redirect_immediately` diaktifkan, pelanggan dialihkan ke `return_url` segera setelah penyelesaian pembayaran, melewati halaman sukses default sepenuhnya.
</Note>

### 14. Memaksa Bahasa

Paksakan checkout untuk ditampilkan dalam bahasa tertentu, menggantikan deteksi bahasa browser pelanggan:

```javascript expandable theme={null}
const session = await client.checkoutSessions.create({
  product_cart: [
    {
      product_id: 'prod_subscription',
      quantity: 1
    }
  ],
  customization: {
    force_language: 'ja'  // Force Japanese language
  },
  customer: {
    email: 'customer@example.jp',
    name: 'Tanaka Yuki'
  },
  return_url: 'https://yourapp.com/success'
});
```

<Tip>
  Gunakan `force_language` saat Anda tahu bahasa pilihan pelanggan (misalnya, dari pengaturan akun mereka) atau saat menargetkan pasar regional tertentu.
</Tip>

**Bahasa yang Didukung:** Arabic (`ar`), Catalan (`ca`), Chinese (`zh`), Dutch (`nl`), English (`en`), French (`fr`), German (`de`), Hebrew (`he`), Indonesian (`id`), Italian (`it`), Japanese (`ja`), Korean (`ko`), Malay (`ms`), Polish (`pl`), Portuguese (`pt`), Romanian (`ro`), Russian (`ru`), Spanish (`es`), Swedish (`sv`), Thai (`th`), Turkish (`tr`)

### 15. Mengumpulkan Bidang Kustom

Kumpulkan informasi tambahan dari pelanggan selama checkout menggunakan bidang kustom:

```javascript expandable theme={null}
const session = await client.checkoutSessions.create({
  product_cart: [
    {
      product_id: 'prod_saas_plan',
      quantity: 1
    }
  ],
  custom_fields: [

## Pratinjau Sesi Checkout

Sebelum membuat sesi checkout, Anda dapat mempratinjau rincian harga termasuk pajak, diskon, dan total. Ini berguna untuk menampilkan harga yang akurat kepada pelanggan sebelum mereka melanjutkan ke checkout.

## Berpindah dari Tautan Dinamis ke Sesi Checkout

### Perbedaan Kunci

Sebelumnya, saat membuat tautan pembayaran dengan Tautan Dinamis, Anda diharuskan menyediakan alamat penagihan lengkap pelanggan.

Dengan Sesi Checkout, hal ini tidak lagi diperlukan. Anda dapat menyampaikan informasi apa pun yang Anda miliki, dan kami akan menanganinya. Sebagai contoh:

* Jika Anda hanya mengetahui negara penagihan pelanggan, hanya berikan itu.
* Alur checkout secara otomatis akan mengumpulkan detail yang hilang sebelum memindahkan pelanggan ke halaman pembayaran.
* Di sisi lain, jika Anda sudah memiliki semua informasi yang diperlukan dan ingin langsung ke halaman pembayaran, Anda dapat menyampaikan data lengkap dan menyertakan `confirm=true` dalam body permintaan Anda.

### Proses Migrasi

Migrasi dari Tautan Dinamis ke Sesi Checkout adalah mudah:

<Steps>
  <Step title="Update your integration">
    Perbarui integrasi Anda untuk menggunakan metode API atau SDK yang baru.
  </Step>

  <Step title="Adjust request payload">
    Sesuaikan payload permintaan sesuai dengan format Sesi Checkout.
  </Step>

  <Step title="That's it!">
    Ya. Tidak diperlukan penanganan tambahan atau langkah migrasi khusus di pihak Anda.
  </Step>
</Steps>
