> ## 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 [Alfa](https://docs.payrails.com/docs/integrations/payment-methods/bank-alfalah) payments from customers in Pakistan with [Thunes](https://www.thunes.com/) as the payment service provider (PSP). The customer selects Alfa, confirms the payment on the Thunes payment page and returns to your site.

## Before you begin

Complete these steps before you send your first Alfa payment through Thunes:

1. Set up a Thunes integration in your workspace with your Thunes merchant ID, API key, and secret key. Payrails uses the secret key to verify Thunes notifications. Follow the [Thunes integration setup guide](https://docs.payrails.com/docs/integrations/payment-providers/thunes.md) if you don't have one yet.
2. Ask Thunes to enable Alfa on your Thunes merchant account, with a payment page whose ID is `alfa`. Payrails opens the Thunes payment page with that ID.
3. In the Payrails Portal, go to **Settings → Integrations**, open your Thunes integration, select **Alfa** under **Payment methods**, and save.
4. Add Alfa as a [payment option](https://docs.payrails.com/docs/integrations/payment-methods/set-up-payment-methods.md) in your workflow.

To test payments before you go live, follow the [Thunes testing guide](https://collection-docs.thunes.com/docs/how-to-test).

## Request fields for Thunes

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` | Required | Payrails returns an error when the customer is missing. |
| `meta.customer.country.code` | Required | Sent to Thunes as the billing country, for example `PK`. |
| `meta.order` | Required | Payrails returns an error when the order is missing. |
| `meta.order.reference` | Required | Sent to Thunes as your order ID. |
| `meta.customer.reference` | Required | Sent to Thunes as your customer ID. |
| `meta.customer.name` | Required | Sent to Thunes as the customer's first name. |
| `meta.customer.email` | Required | Sent to Thunes as the customer's email. |
| `meta.customer.lastName` | Optional | Sent to Thunes as the customer's last name. |

## Authorize an Alfa payment

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

```json Authorize request theme={null}
{
  "amount": {
    "value": "1500.00",
    "currency": "PKR"
  },
  "paymentComposition": [
    {
      "integrationType": "api",
      "paymentMethodCode": "alfa",
      "amount": {
        "value": "1500.00",
        "currency": "PKR"
      }
    }
  ],
  "meta": {
    "customer": {
      "reference": "customer-1234",
      "email": "ayesha.khan@example.com",
      "name": "Ayesha",
      "lastName": "Khan",
      "country": {
        "code": "PK"
      }
    },
    "order": {
      "reference": "order-1234"
    }
  },
  "returnInfo": {
    "success": "https://example.com/success",
    "error": "https://example.com/error"
  }
}
```

After the customer confirms the payment, Thunes 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 Thunes handles Alfa

* Payrails opens the Thunes payment page whose ID is `alfa`, and sends the payment amount as a decimal value in PKR.
* Thunes notifies Payrails of the final result. When Thunes reports the payment as charged, Payrails records the authorization and the capture together.
