> ## 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.

Yapı Kredi WorldPay is the digital wallet of Yapı Kredi Bank in Türkiye. Customers pay in the WorldPay app, by scanning a QR code or following a link that opens the app, without entering card details at checkout.

Payrails processes Yapı Kredi WorldPay through one payment service provider (PSP): Craftgate. Open the Craftgate guide below for its setup steps and request examples.

## How a Yapı Kredi WorldPay payment works

Yapı Kredi WorldPay is a redirect payment method:

1. The customer selects Yapı Kredi WorldPay at checkout.
2. Payrails returns the next step from Craftgate: a page with a QR code, or a link that opens the WorldPay app.
3. The customer scans the QR code or opens the app, and approves the payment in the WorldPay app.
4. Craftgate sends the result back to Payrails, and Payrails updates the payment.

Each payment is single-use: the customer approves every payment on its own. Payrails captures Yapı Kredi WorldPay payments immediately, so a successful payment is final. To return funds, [refund the payment](https://docs.payrails.com/docs/orchestration/payment-acceptance/refund-a-payment.md).

## Supported currencies and countries

Yapı Kredi WorldPay is a domestic payment method in Türkiye. Use TRY (Turkish lira).

Yapı Kredi WorldPay is available to customers based in:

Yapı Kredi WorldPay is a one-off payment method: Craftgate doesn't save a Yapı Kredi WorldPay instrument for later merchant-initiated transactions (MIT).

## Ways to integrate Yapı Kredi WorldPay

* **Payrails SDK:** the [Web SDK](https://docs.payrails.com/docs/sdks/web.md) shows Yapı Kredi WorldPay when your workflow returns it as a payment option, and takes the customer to the QR code page or the WorldPay app. To control how this opens, listen for the [`actionRequired` event](https://docs.payrails.com/docs/sdks/web/guides/action-required-event).
* **Payrails API:** call [lookup payment options](https://docs.payrails.com/docs/orchestration/payment-acceptance/lookup-payment-options.md), then authorize with `ykbWorldPay` as the `paymentMethodCode`. The Craftgate guide explains how to handle the response.

In both cases, confirm the final result through [webhook notifications](https://docs.payrails.com/docs/orchestration/payment-acceptance/receive-notifications.md) or the execution status before you fulfill the order.
