Purchase by using Payment Page

General information

In the Przelewy24 method, to perform a purchase by using Payment Page, the merchant web service should send a request with all the required parameters and signature to the ECommPay URL and get the callback with the payment result from the payment platform. When opening Payment Page, you can have Payment Page opened with the Przelewy24 method selected. For more information about preselecting payment methods, see in Preselecting payment method.

The full sequence and particularities of the purchase process are provided below.

The sections that follow discuss in more details the request format and the Payment Page parameters to use in the Przelewy24 payment method and provide the information on the format of callbacks with payment results. For the general information on how to use the API, see Payment Page API Description.

Request format

There are several things you need to consider when requesting a payment through the Przelewy24 method:

  1. You must provide values for the basic minimum of parameters. Listed below are the parameters that are mandatory for any payment method:
    • project_id—the project ID obtained from ECommPay
    • payment_id—payment ID unique within the project
    • payment_currency—payment currency in ISO-4217 alpha-3 format
    • payment_amount—payment amount in minor units
    • customer_id—customer ID unique within the project
  2. The currency of payment can be PLN or EUR.
  3. To open Payment Page, pass the language code in the language_code parameter in the request for opening. For more information, see Interface language support.
  4. There are more mandatory parameters:
    • customer_email—email address
    • customer_first_name—first name
    • customer_last_name—last name
  5. If you need to have payment form displayed with the Przelewy24 method selected, set the force_payment_method parameter to przelewy24.
  6. If required, you can also add any other additional parameters Payment Page supports.
  7. After you specify all the parameters you need, you must create the signature for the request. For instructions on how to sign a payment request, see Signature generation and verification.

Thus, a correct payment request in the Przelewy24 method must include project, and payment IDs, customer data, signature, the currency and the amount of a payment in the appropriate currency, as shown in the following example:

EPayWidget.run(
    { payment_id: 'X03936', 
      payment_amount: 10000, 
      payment_currency: 'PLN', 
      project_id: 239,
      customer_id: 'customer1',
      language_code: en,
      customer_email: 'example@gmail.com',
      customer_first_name: 'John',
      customer_last_name: 'Johnson',
      signature: "kUi2x9dKHAVNU0FYldJrxh4yo+52Kt8KU\/RLCvhtT4DqtVUkDJrOcZCwX6R\/ekpZhkIQg=="
    }
)

For information about all parameters available in the Przelewy24 method , see Payment Page invocation parameters.

Callback format

The Przelewy24 method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks.

The following is the example of a callback with an information about successful 100,00 PLN purchase on account 2626324568 in the 238 project.

  17. The customer receives the payment result on the web service.

The sections that follow discuss in more details the request format and the Gate parameters to use in the Przelewy24 payment method and provide the information on the format of callbacks with purchase results.

Request format

There are several things you must consider when using purchase requests in the Przelewy24 method:
  1. You perform refunds by sending the /v2/payment/online-banking/przelewy24/sale/ request by using POST (HTTP) method. This is an online banking request group: /v2/payment/online-banking/{payment_method}/sale
  2. The following objects and parameters must be specified in any request:
    • Object general—general purchase information:
      • project_id—project identifier
      • payment_id—unique purchase identifier
      • signature—signature created after you specify all the required parameters. For more information about signature generation, see Signature generation and verification
    • Object customer—customer information:
      • id—the ID of the customer within the merchant project
      • email—email address
      • first_name—first name
      • last_name—last name
      • ip_address—customer IP address
    • Object payment—purchase information:
      • amount—purchase amount
      • currency—payout currency in the ISO-4217 alpha-3 format.
    • return_url—URL for customer returning from the bank site:
      • return—site URL for returning
  3. The currency of payment can be PLN or EUR.
  4. If required, you can also add any other additional parameters Gate supports.

Thus, a correct payment request in the Przelewy24 method must include project and payment IDs, customer data, currency and amount of the purchase, as shown in the following example:

Figure: Example of a purchase request

{
    "general": {
        "project_id": 2990,
        "payment_id": "payment_id",
        "signature": "PJkV8ej\/UG0Di8NN5e7cV+VHq3LwY3T\/pOMeSaRfBaNIipTv+AWoXW\/9MTO8yJA=="
    },
    "customer": {
      "ip_address": "1.1.1.1",
      "last_name": "Johnson",
      "first_name": "John",
      "email": "example@mail.com",
      "id": "123"
    },
    "payment": {
      "amount": 1000,
      "currency": "EUR"
    },
    "return_url": {
      "return": "http://merchantsite.com"
    }
}

Formats of the customer redirection data

To redirect a customer from the web service to the Przelewy24 site, you must receive a callback from the payment platform containing the URL for redirection in the redirect_data.url parameter and data to be sent in the request body in the redirect_data.body parameter, and use these parameters when opening the HTML page using the method specified in the redirect_data.method parameter.

The following is the callback fragment containing the data for redirection.

   "redirect_data": {
                    "body": [],
                    "method": "GET",
                    "url": "https://p24.de/p24?tx=421417103&rs=uv333db1260e2"
                }

Refund by using Gate

General information

Przelewy24 supports full and partial refunds processing. To perform a refund through the Przelewy24 method, merchant's web service sends a request with all the required parameters and signature to ECommPay URL, and receives a callback with the payment result. The full sequence of the refund process is provided below.



Figure: Refund sequence in the Payment Page method

  1. A customer orders a refund by using merchant's web service.
  2. Merchant's web service sends the refund request for processing the refund by using Gate to the appropriate ECommPay URL.
  3. Gate redirects the request to the ECommPay payment platform.
  4. The payment platform performs all the necessary check and processes the request.
  5. The reply with the request processing results is sent to the merchant's web service. For more information, see Response format.
  6. The payment platform redirects the refund request to the Przelewy24 service.
  7. The refund is processed on Przelewy24 side.
  8. Przelewy24 sends the result notification to the payment platform.
  9. The payment platform sends a callback with the payment result to the web service.
  10. The customer receives the information about the receipt of the requested funds from the web service.

The sections that follow discuss in more details the request format and the Gate parameters to use in the Przelewy24 payment method and provide the information on the format of callbacks with refund results.

Request format

There are several things you must consider when using refund requests in the Przelewy24 method:
  1. You perform refunds by sending the /v2/payment/online-banking/przelewy24/refund/ request by using POST (HTTP) method. This is an online banking request group: /v2/payment/online-banking/{payment_method}/refund
  2. The following objects and parameters must be specified in any request:
    • Object general—general payment information:
      • project_id—project identifier
      • payment_id—unique payment identifier
      • signature—signature created after you specify all the required parameters. For more information about signature generation, see Signature generation and verification
    • Object customer—customer information:
      • ip_address—customer IP address
    • Object payment—refund information:
      • description—comment or description
      • amount—refund amount in minor units (mandatory for partial refund only)
      • currency—refund currency in ISO-4217 alpha-3 format (mandatory for partial refund only)
  3. If required, you can also add any other additional parameters Gate supports.

Thus, a correct refund request in the Przelewy24 method must include project and payment IDs, customer IP address, currency and amount of the refund, as shown in the following example:

Callback format

The Przelewy24 method uses the standard format for callbacks to deliver refund results. For more information, see Callbacks.

Here is an example of callback with an information about successful 100,00 PLN refund for the customer account 2626324568 in the 238 project.

Analysis of payments results

As with other payment methods ECommPay offers, when using the Przelewy24 method, you have several options to analyse the information about payments and operations performed by using the method—alone or in conjunction with other methods.

You can load and analyse all the necessary information in Dashboard, for instance you can use the analytic panels on the Analytics tab to this end.

Also, you can export the information for further analysis by using third party analytical tools. The following options are available:

  • Dashboard allows you to download reports in CSV and XLS formats—by using the tools on the Payments tab. You can perform export as a one-time download to your local computer or have payment data regularly exported and delivered to email addresses you specify.
  • Data API allows you to have payment information exported in JSON format and delivered to a URL you specify. The payment information is exported by using the /operations/get queries.

If you have any further questions regarding payment data analysis, contact ECommPay technical support.
