The sections that follow provide detailed information about what you need to perform payments and how you can analyse the information on payments and operations.

Purchase by using Payment Page

General information

In the MCash Wallet 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 MCash Wallet 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.



Figure: Purchase sequence by using Payment Page

  1. A customer initiates a purchase on the merchant's web service.
  2. The web service sends the request for purchase by using Payment Page to the specified ECommPay URL.
  3. The request for opening is redirected to the payment platform.
  4. The payment platform performs the initial request processing that involves validation of the required parameters and signature.
  5. Requested Payment Page is generated into the ECommPay payment platform as specified in the project settings and the request parameters.
  6. Payment Page is displayed to the customer.
  7. The customer selects the MCash Wallet method.
  8. The payment platform receives the purchase request for payment processing from Payment Page.
  9. The payment platform performs the internal purchase request processing and sends it to the MCash Wallet service.
  10. The purchase request is processed on the MCash Wallet service side.
  11. The MCash Wallet service generates the data for redirecting the customer to its website form and sends it to the payment platform.
  12. The payment platform sends the customer redirection data to Payment Page.
  13. The customer is redirected to the MCash Wallet website.
  14. The customer completes all the payment steps required.
  15. The payment is processed on the MCash Wallet side.
  16. The result is displayed to the customer on the MCash Wallet website.
  17. The customer is redirected to Payment Page.
  18. The MCash Wallet service sends the result notification to the payment platform.
  19. The payment platform sends a callback with the payment result to the web service.
  20. The payment platform sends the result to Payment Page.
  21. A page with the payment result information is displayed to the customer on Payment Page.

The sections that follow discuss in more details the request format and the Payment Page parameters to use in the MCash Wallet 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 using the MCash Wallet 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 only be MYR.
  3. There are the mandatory parameters: customer_first_name, customer_last_name, customer_email, customer_phone—the first and last names, email address and phone number of the customer.
  4. If you need to have payment form displayed with the MCash Wallet method selected, set the force_payment_method parameter to mcash.
  5. If required, you can also add any other additional parameters Payment Page supports. For information about all parameters available, see Payment Page invocation parameters.
  6. 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 MCash Wallet method must include project and payment IDs, the currency and the amount of the payment in the appropriate currency, and the customer data, as shown in the following example:

EPayWidget.run(
    { payment_id: 'X03936', 
      payment_amount: 500000, 
      payment_currency: 'MYR', 
      project_id: 250,   
      customer_id: 'customer1',
      customer_first_name: 'Putra',
      customer_last_name: 'Cane',
      customer_phone: '60321669552',
      customer_email: 'putra@mail.com'
      signature: "kUi2x9dKHAVNU0FYldJrxh4yo+52Kt8KU+Y1Y4HASCQ9vySO\/RLCvhtT4DqtVUkDJrOcZzUCwX6R\/ekpZhkIQg=="
    }
)

Callback format

The MCash Wallet 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 5000,00 MYR purchase made by a customer in the 635 project.

Purchase by using Gate

General information

In the MCash Wallet methods, when processing a purchase by using Gate, the merchant web service is required to do the following:

  1. Send a request with all the required parameters and signature to the ECommPay URL.
  2. Perform redirection of a customer to the MCash Wallet service.
  3. Receive the callback with the payment result from the payment platform.

The following diagram provides the detailed picture of the payment processing procedure.

Figure: Purchase sequence by using Gate

  1. A customer initiates a purchase through MCash Wallet on the merchant's web service side.
  2. The web service sends the request for processing the purchase by using Gate to the specified ECommPay URL.
  3. The payment platform receives the request for processing the purchase from Gate.
  4. The payment platform performs the initial request processing that includes validation of the required parameters and signature.
  5. The payment platform sends the response with request receipt confirmation and correctness check result to the web service. For more information, see Response format.
  6. The payment platform performs the internal payment request processing and redirects the request to the MCash Wallet service.
  7. The request is processed on the MCash Wallet side.
  8. The MCash Wallet service sends the data for redirecting the customer to the MCash Wallet service to the payment platform.
  9. The payment platform sends the callback with the redirection data in the redirect_data object to the web service.
  10. The customer is redirected from the web service to the MCash Wallet service.
  11. The customer completes all the payment steps required.
  12. The payment is processed on the MCash Wallet side.
  13. The result is displayed to the customer.
  14. The customer is redirected to the merchant's web service.
  15. The MCash Wallet service sends the payment result notification to the payment platform.
  16. The ECommPay payment platform sends a callback to the web service.
  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 MCash Wallet 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 MCash Wallet method:
  1. You perform purchase by sending the /v2/payment/cash/mcash/sale request by using POST (HTTP) method. This is a cash payments request group: /v2/payment/wallet/{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:
      • ip_address—IP address
      • first_name—first name
      • last_name—last name
      • email—email address
      • phone—phone number
      • id—unique ID within the merchant project
    • Object payment—purchase information:
      • amount—purchase amount
      • currency—purchase currency in the ISO-4217 alpha-3 format
      • description—payment description
  3. The currency of a purchase can only be MYR.
  4. If required, you can also add any other additional parameters Gate supports.

Thus, a correct payment request through the MCash Wallet 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": 318,
    "payment_id": "EP5fb7-bdg6",
    "signature": "testiuhgfcvbnm8f/kjhg\lkjhgvxbnmcvgfjdssAPOPKSJiojhbnm"
  },
  "payment": {
    "amount": 50000,
    "currency": "MYR",
    "description": "payment"
  },
  "customer": {
    "first_name":"Petra",
    "last_name":"Davis",
    "ip_address":"172.10.123.11",
    "phone":"640991025894",
    "email":"d@df.com",
    "id": "customer1"
  }
}

Formats of the customer redirection data

To redirect a customer from the web service to the MCash Wallet 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 redirection data.

"redirect_data": {
    "body": {
      "merchant": "eghlmerchant",
      "type": "payment",
      "trx_id": "00000024460000002029",

Analysis of payments results

As with other payment methods ECommPay offers, when using the MCash Wallet 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.
