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"
}

Integrating Apple Pay

Integrating Apple Pay involves the following:

• Configuring your Apple Developer Account and adding Apple Pay to your checkout page.

• Integrating Apple Pay with your PaymentsOS transaction flows.

Configuring your Apple Developer Account

Before following the procedures below, contact us to request a CSR (Certificate Signing Request) certificate. Apple requires this certificate. Then proceed as follows:

1. Configure your Apple Developer Account for Apple Pay. For help, see this video on the Apple developer site. Note that you will be required to upload the CSR (Certificate Signing Request) certificate as part of the configuration procedures.

2. When setting up your account in step 1, you will generate a apple_pay.cer file. Send us this file so that we can store it in your account.

3. Integrate Apple Pay in your checkout page using Apple's Javascript API, as explained on the Apple developer site.

Now proceed to integrate Apple Pay with PaymentsOS.

Integrating Apple Pay with PaymentsOS

Once your Apple Developer account is setup and you've added Apple Pay to your checkout page, you are ready to integrate Apple Pay with PaymentsOS.

When the customer chooses to pay with Apple Pay, Apple will return a token to your web page. Here's a sample token:

{
  "version": "EC_v1",
  "data": "DjI8Ez7nPhVo742aGEzABz/TfxCPt9LSdf2/h+0xIgVJbi3fQqd4lv3ogoTI3SQ7vZrDAWI8g2lbd5sflXBHc0z+wSeybsCcqZB3n1edRFXU7+6DYmdhFFWWCejwUc6XZWmsSaVNEQf+Kc0SeYrj8Eskdapj8bYX/QXxXSPqS4IKSjB+f3O0gUXSq7LK/jA9dl+BbWW0l3gXERU6n5rcYndO5rnjiwNUpnm7EMIMfNU+IPbsubpL82kbL2MdMJB1grel03J4JKld6G0pFSmjR2mF/xBY/yKkADRhoQkVlDRicuKVMpdRXXbIQjw/yRkLv/u8iy1wXI5YmEBB+W4QpPYsuxys94gMPaKhcaEK/OaT099aFrNBezbuLMTcTzbhXOpPwWn9pkAK0eZNOQ==",

  }
}

Now pass the token's fields as key-value pairs in the payment_method.additional_details field of the Create Authorization request. Make sure to also include all fields from the token's header object using key names as shown in the example below (include just the fields, not the entire object). Here's a sample request body:

{
  "payment_method": {
    "source_type": "ewallet",

      "version": "EC_v1"
    }
  }
}

You can now complete the transaction by invoking the Create Capture request.

Integrating Google Pay

Integrating Google Pay involves the following:

• Adding Google Pay to your checkout page.

• Integrating Google Pay with your PaymentsOS transaction flows.

Adding Google Pay to your Checkout Page

Start by adding Google Pay to your checkout page, as explained in the Google developer documentation. For guidelines that detail how to reference the Google Pay brand within your website, see the brand guidelines published on the Google developer documentation site.

Now proceed to integrate Google Pay with PaymentsOS.

Integrating Google Pay with PaymentsOS

Once you've added Google Pay to your checkout page, you are ready to integrate Google Pay with PaymentsOS.

When the customer chooses to pay with Google Pay, Google will return a token to your web page. Here's a sample token:

{
  "signature": "MEYCIQCbOYSGLvmt5mfJROZPJ/KiRhNKzQJfgwL1YcGeC1LhLQIhAOVQ5PdCbmHasSDmaWDNyujbKzvWC34ZpSB+LNcGQfh2",

}

Now pass the token's fields as key-value pairs in the payment_method.additional_details field of the Create Authorization request. Here's a sample request body:

{
  "payment_method": {
    "source_type": "ewallet",
    "type": "untokenized",
    "vendor": "googlepay",
    "additional_details": {

    }
  }
}

You can now complete the transaction by invoking the Create Capture request.

Integrating BLIK

When integrating BLIK in your payment flow, you have two options to choose from:

• You redirect your customers to the BLIK authentication page, where they enter their BLIK authorization code and complete the transaction.

• You allow customers to enter their BLIK authorization code directly in your checkout page, without redirecting them to the BLIK authentication page. When choosing this option, you can also allow your customers to sign-up for a BLIK billing agreement. With a BLIK billing agreement in place, customers can pay with a single 'click' and do not need to enter their authorization code each time they want to complete a payment.

Implementing a Redirect to the BLIK Authentication Page

If desired, you can integrate BLIK by redirecting your customers to the BLIK authentication page for entering their BLIK authorization code and completing the transaction. To do so, pass the following payment_method object in the body of the Create Authorization request. Notice that the payment_method object must also include an additional_details.bank_name field, with a value of blik_redirect.

{
  "payment_method": {
    "source_type": "ewallet",
    "type": "untokenized",
    "vendor": "blik",
    "additional_details": {
      "bank_name": "blik_redirect"
    }
  }
}

Processing the BLIK Authorization Code in your Checkout Page

Rather then redirecting your customers to the BLIK authentication page for entering their authorization code, you can also process the BLIK authorization code directly in your checkout page. Simply prompt your customers for their authorization code and pass it in the payment_method.additional_details.authorizationCode field of the Create Authorization request. You must also pass a payment_method.additional_details.bank_name field with a value of blik_checkout_page.

{
  "payment_method": {
    "source_type": "ewallet",
    "type": "untokenized",
    "vendor": "blik",
    "additional_details": {
      "authorizationCode":"777123",
      "bank_name": "blik_transparent"
    }
  }
}

Implementing One-click BLIK Payments

If you process the BLIK authorization code directly in your checkout page, you can also allow your customers to sign-up for a BLIK billing agreement. With a BLIK billing agreement in place, customers can pay with a single 'click' in all subsequent transactions and do not need to enter their authorization code each time they want to complete a payment.

To sign-up a customer for a BLIK billing agreement, invoke the Create Authorization request and pass a payment_method.additional_details.register field with a value of true. Of course, customers will still need to enter their authorization code when signing up. So when signing-up the customer, make sure to still pass this code in the payment_method.additional_details.authorizationCode field. You must also pass a payment_method.additional_details.bank_name field with a value of blik_token. Here's a sample request body:

{
  "payment_method": {
    "source_type": "ewallet",
    "type": "untokenized",
    "vendor": "blik",
    "additional_details": {
      "authorizationCode":"777123",
      "bank_name": "blik_token",
      "register": "true"
    }
  }
}

The response of the Create Authorization request will include a token in the provider_data.additional_information.blik_payment_method_token field. This token represents the BLIK billing agreement. Grab the token and store it in a customer object, as explained in Saving the Token. You can then pass the token in all subsequent Create Authorization requests (see how to Use the Saved Token to Accept a Payment). You pass the token, like so:

Here's a sample

"payment_method": {
  "type": "billing_agreement",
  "token": "your token"
},
