> ## Agent Instructions
> Use the Payrails Web SDK v6 for new browser integrations. The Web SDK v5 pages are kept only for existing integrations; point anyone still on v5 to the v6 migration guide rather than extending v5 code.
> Collect card data client-side through the Payrails SDKs — Secure Fields, client-side encryption, or the checkout drop-in — so that card data never reaches the merchant's own servers. Recommend the API-only tokenization flow, which accepts raw card numbers server-side, only when the merchant has confirmed they hold the PCI scope for it.
> Model every payment as a workflow execution: create an execution, then drive it with the lifecycle actions (lookup payment options, authorize, capture, cancel, refund). Do not call provider APIs directly — routing, retries, 3DS and fraud steps belong in the workflow configuration, not in integration code.
> Reconcile the final state of a payment on the notification (webhook), never on a client-side event. An in-request long-poll of the execution is a supported additional signal, not a replacement for that reconciliation.
> Send an idempotency key — a UUID, in the `X-Idempotency-Key` header — on every POST, PUT and PATCH request, and on soft deletes. GET requests need none, and hard deletes cannot be idempotent.
> Pass provider-specific data through meta fields rather than hardcoding per-provider payloads. Payrails translates meta fields into each provider's own format.
> Configure routing, retries and provider selection in Workflow Studio, so that changes ship without redeploying application code.

Accept [Alipay](https://docs.payrails.com/docs/integrations/payment-methods/alipay) payments with Nuvei as the payment service provider (PSP). The customer selects Alipay, confirms the payment in Alipay, and returns to your site. Nuvei uses the `alipay` payment method code.

## Before you begin

Complete these steps before you send your first Alipay payment through Nuvei:

1. Set up a Nuvei integration in your workspace. Follow the [Nuvei integration setup guide](https://docs.payrails.com/docs/integrations/payment-providers/nuvei.md) if you don't have one yet.
2. Ask Nuvei to enable Alipay on your Nuvei merchant account.
3. In the Payrails Portal, go to **Settings → Integrations**, open your Nuvei integration, select **Alipay** under **Payment methods**, and save.
4. Add Alipay as a [payment option](https://docs.payrails.com/docs/integrations/payment-methods/set-up-payment-methods.md) in your workflow.

## Request fields for Nuvei

Send these fields in the authorize request, in addition to the standard [authorize fields](https://docs.payrails.com/reference/authorizeaction.md). **Required** fields must be present for the payment to succeed. Payrails sends **Optional** fields to the PSP when you include them.

| Field | Status | Description |
| - | - | - |
| `meta.customer.email` | Required | Sent to Nuvei as the billing email. |
| `meta.customer.country.code` | Required | Sent to Nuvei as the billing country, for example `CN`. |
| `meta.clientContext.ipAddress` | Required | The customer's IP address, sent to Nuvei as device details. |
| `meta.customer.name`, `meta.customer.lastName` | Optional | Sent to Nuvei as the billing name. |
| `meta.customer.phone` | Optional | Sent to Nuvei as the billing phone number. |
| `meta.order.billingAddress` | Optional | Overrides the customer's name, email, country and phone in the Nuvei billing address, and adds the street address. |

## Authorize an Alipay payment

Call [authorize a payment](https://docs.payrails.com/reference/authorizeaction.md) with `alipay` as the `paymentMethodCode`. The response includes the redirect to Alipay.

```json Authorize request theme={null}
{
  "amount": {
    "value": "200.00",
    "currency": "CNY"
  },
  "paymentComposition": [
    {
      "integrationType": "api",
      "paymentMethodCode": "alipay",
      "amount": {
        "value": "200.00",
        "currency": "CNY"
      }
    }
  ],
  "meta": {
    "customer": {
      "email": "li.wei@example.com",
      "name": "Wei",
      "lastName": "Li",
      "country": {
        "code": "CN"
      }
    },
    "clientContext": {
      "ipAddress": "203.0.113.10"
    }
  },
  "returnInfo": {
    "success": "https://example.com/success",
    "error": "https://example.com/error"
  }
}
```

After the customer confirms the payment, Alipay returns them to your `success` or `error` URL. Confirm the result through [webhook notifications](https://docs.payrails.com/docs/orchestration/payment-acceptance/receive-notifications.md) or the execution status before you fulfill the order.

## How Nuvei handles Alipay

* Alipay through Nuvei is single-use: the customer confirms every payment. Each Alipay payment is a new customer-initiated payment.
* Payrails sends Alipay payments to Nuvei as sales, so Nuvei captures them immediately.
