The following sections list the integration procedures that are specific to this provider.

Redirecting your customer for Asynchronous Payment Flows

You'll need to redirect your customer for the following payment methods:

• Credit card payments that include 3D Secure
• PBL bank transfers
• payment_wall payments

When you send a post authorization request, we will return an authorization resource containing an authorization.redirection.url, and a status of pending. Redirect your customer to this URL, so that they can authenticate themselves and complete the payment flow:

• For credit card payment methods, the redirection is to a 3D Secure site.
• For the PBL payment method, the redirection is to your customer's bank authentication site.
• For the payment_wall payment method, the redirection is to a PayU Single Platform hosted page, where your customer can select a payment method.

Once the authentication / payment method selection process at the provider is done, we'll redirect your customer's browser back to your site, using the merchant_site_url (that you provided in the post authorization). We've included the following URL parameters in the merchant_site_url, to provide you with the context of the page that you'll need to load: payment_id, authorization_id, and status (of the authorization). Here's an example:

<merchant_site_url>
  ?payment_id=dd1fbe34-4636-4a61-8cb1-27ac8a175284
  &authorization_id=aec1c306-e0f7-452b-8fb5-5b34489e9d10
  &status=Pending

If you do not pass a merchant_site_url, the user will not be able to complete the 3DS authentication flow. The response data of the Create Authorization request will indicate this in the additional_details.error field:

{
  "additional_details": {
    "error": "The transaction requires 3DS authentication, but cannot be completed as the merchant_site_url was not provided"
  }
  ...
}

Parsing the Response of the Retrieve Supported Payment Methods Request

When building your checkout page, you can choose to invoke the Retrieve Supported Payment Methods request to retrieve a list of supported payment methods. The response will have a structure similar to the following:

...
{
 "supported_payment_methods": [
    {
      "display_name": "Płacę później",
      "vendor": "dp",
      "source_type": "bank_transfer",
      "status": "ENABLED",
      "logo_url": "https://static.payu.com/images/mobile/logos/pbl_dp.png"
    },
    {
      "display_name": "BLIK",
      "vendor": "blik",
      "source_type": "bank_transfer",
      "status": "ENABLED",
      "logo_url": "https://static.payu.com/images/mobile/logos/pbl_blik.png"
    }
    ...
 ],
 ...
}

When creating a transaction flow for PBL and Payment Wall, you are required to pass in the bank_name in the request body of the Create Authorization request. Contrary to what you would expect, the bank_name corresponds to the vendor field returned in the response data of the Retrieve Supported Payment Methods request.

Here's a sample Create Authorization request for a bank transfer using the PBL payment method. Notice that bank_name is populated with the value of the vendor field you obtained when invoking the Retrieve Supported Payment Methods request. You should specify a bank_name value, regardless of the source_type returned by the Retrieve Supported Payment Methods request.

{
  "merchant_site_url": "http://www.abc.com/return-url",
  "payment_method": {
    "source_type": "bank_transfer",
    "type": "untokenized",
    "vendor": "PBL",
    "additional_details": {
      "bank_name": "blik", // This is the vendor
      "language": "pl"
    }
  },
  "reconciliation_id": "40762342"
}

• For the live environment use: "t", "payment_wall".
• For the test environment use: "m", "o", "p", "c", or "payment_wall".
