Purchase by using Payment Page

General information

In the RBK Bank 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 either allow your customer to select the RBK Bank methods from the list of other payment methods on Payment Page or have Payment Page opened with the RBK Bank 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 provide details the request format and the Payment Page parameters to use in the RBK Bank 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 must consider when performing a purchase through the RBK Bank 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 the payment can be EUR, KZT, RUB, USD.
  3. To preselect RBK Bank as the payment method on Payment Page for customers, pass the code rbk in the force_payment_method parameter in the request for opening.
  4. If required, you can also add any other additional parameters Payment Page supports. For information about all parameters available in the RBK Bank method, see Payment Page invocation parameters.
  5. 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 through the RBK Bank method must include project and payment IDs, signature, currency and amount of the purchase, as shown in the following example:

EPayWidget.run(
    { project_id: 198, 
      payment_id: 'X03936',
      payment_amount: 10000, 
      payment_currency: 'KZT,
      customer_id: 'customer1',
      signature: "kUi2x9dKHAVNU0FYldJrxh4yo+52Kt8KU+Y1Y4HASCQ9vySODJr...=="
    }
)

Callback format

In the RBK Bank method, the callbacks that deliver purchase results use the standard format described in Callbacks.

The following is the example of a callback with an information about successful 10,000.00 KZT purchase made by the customer in the 238 project.

The sections that follow discuss in more details the request format and the Gate parameters to use in the RBK Bank payment method and provide the information about formats of the data for redirecting customers and the information about the format of callbacks with payment results. The general information about working with API see in the API Description section.

Request format

There are several things you must consider when using purchase requests in the RBK Bank method:
  1. You perform purchase by sending the /v2/payment/online-banking/bankrbk24/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 the request:
    • Object general—general purchase information:
      • project_id—project identifier
      • payment_id—unique payout 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
      • ip_address—IP address
      • phone—phone number
    • Object payment—purchase information:
      • amount—purchase amount in minor units
      • currency—purchase currency in ISO-4217 alpha-3 format
  3. The currency of the payment can be EUR, KZT, RUB, USD.
  4. If required, you can also add any other additional parameters Gate supports.

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

Figure: Purchase request example

{
    "general": {
      "project_id": 198,
      "payment_id": payment_id,

      "ip_address": "1.1.1.1",
      "phone": "79017525555",
      "id": "123"
   }
}

Formats of the customer redirection data

To redirect a customer from the web service to the RBK Bank service, 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: lifetime–time in seconds when the payment should be completed, id–payment identifier on the RBK Bank service side, and use these parameters when opening the bank's HTML page using the method specified in the redirect_data.method parameter.

The following is the callback fragment containing the redirection data.

  "redirect_data": {
                    "body": {
                        "lifetime": 86400,
                        "id": 50416966
                    },

Analysis of payments results

As with other payment methods ECommPay offers, when using the RBK Bank 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.
