Przelewy24 is a Poland-based real-time online bank transfer payment method, often referred to as P24. Przelewy24 is a supported browser payment method in the Mastercard Gateway. This page describes integration details specific to Przelewy24.

It is recommended that you read the [integration guidelines for browser payments](https://developer.mastercard.com/mastercard-gateway/documentation/payment-methods/imp-brow-pay-int/index.md) before building the Przelewy24 integration.

Przelewy24 browser payments are only supported for transactions in the EUR and PLN currency.

## Prerequisites {#prerequisites}

To offer the Przelewy24 payment method through the Mastercard Gateway,

* Be registered with your browser payments service provider
* your merchant profile on the Mastercard Gateway must be configured using the details of your account with the browser payments service provider, and
* you must have a bank account in one of the supported currencies that are registered against your merchant account at your browser payments service provider.

## Przelewy24 integration {#przelewy24-integration}

### Przelewy24 through Hosted Checkout {#przelewy24-through-hosted-checkout}

Hosted Checkout integration allows you to collect payment details from your payer through an interaction that the Mastercard Gateway hosts and displays.

From Mastercard Gateway API version 65 and later, Przelewy24 is automatically available as a payment method once your payment service provider enables and configures you for this payment method.

For details, see [Browser Payments through Hosted Checkout Integration](https://developer.mastercard.com/mastercard-gateway/documentation/payment-methods/imp-brow-pay-int/index.md#browser-payments-through-hosted-checkout-integration).

### Przelewy24 through Direct Payment {#przelewy24-through-direct-payment}

Direct Payment integration allows you to offer the Przelewy24 payment method on your own checkout page.

Alert: Przelewy24 is supported from Mastercard Gateway API version 64 and later.

<br />

In addition to the standard fields required in a browser payment request, provide the following fields in the [Initiate Browser Payment](https://developer.mastercard.com/mastercard-gateway/documentation/api-reference/v100/rest/api-ops/index.md#browser-payment) request:

#### Common fields {#common-fields}

* `sourceOfFunds.type` = Przelewy24
* `browserPayment.operation` = PAY (Przelewy24 does not support the Authorize operation)
* `customer.email` = Email address of a payer
* `sourceOfFunds.provided.przelewy24.bankAccountHolder` = Name of the bank account holder for the payer's bank account

##### Preferred Language {#preferred-language}

You can set the language that you prefer Przelewy24 to use for the pages that are displayed to the payer by providing the browserPayment.preferredLanguage field in the Initiate Browser Payment request. However, the language will be used only if Przelewy24 supports it.
