Bank transfers in Vietnam

Interaction diagram

Payment processing by using the Bank transfers in Vietnam payment method requires merchant's web service, one of Monetix interfaces (Payment Page or Gate), and the Monetix payment platform, as well technical facilities of the provider.

Operations support

	Interfaces			Amounts, VND		Times
	Payment Page	Gate	Dashboard	minimum	maximum	basic	threshold

* Refer to your Monetix key account manager for more information.

You can check the payment amount limits in your project by using Dashboard. To check your payment amount limits, go to Dashboard, select the Projects section and click the Payment methods tab.

Processing scenarios

In the Bank transfers in Vietnam method, purchase can be performed either by redirecting customer to the provider service or by displaying the payment instructions to the customer. Refer to your key account manager at the Monetix for information about what payment scenario to use.

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

Restrictions

The number of purchases using the Bank transfers in Vietnam method for the same user (with the same customer_id) for specific amount can be limited. In other words, if the user initiates multiple identical purchases but completes none of them, the purchases are combined in a single series in which only the data for the first purchase is sent to the provider service. Once the last purchase in the series is completed and assigned the final status, the rest of the purchases in the series are declined and the platform sends callbacks with the 3613 response code. (For more information about the codes, see Operation statuses and response codes.)

Monetix reserves the right to change the time-out period and the allowed number of attempts and will notify of any changes of these limits in a separate message.

Supported banks

Payments with Bank transfers in Vietnam are carried out through banks that support the method. When using Payment Page, customer generally selects the bank in the payment form, although in payments that use Payment Page with pre-selected payment method and bank or Gate, the customer must select the bank on the web service side and request must contain the bank ID.

The tables below provide information about supported banks. The list is provided for informational purposes only.

General information

In the Bank transfers in Vietnam method, to perform a purchase by using Payment Page, the merchant web service is required to send a request with all the required parameters and signature to the Monetix URL and accept the callback with the payment result from the payment platform. When opening Payment Page, you can have Payment Page opened with the Bank transfers in Vietnam method preselected. For more information about preselecting payment methods, see Preselecting payment methods. 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 Bank transfers in Vietnam payment method and provide the information about 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 Bank transfers in Vietnam method:

1. You must provide values for the basic minimum of parameters. Listed below are the parameters that are required for any payment method:
   • project_id—project ID obtained from Monetix
   • payment_id—payment ID unique within the project
   • customer_id—unique ID of the customer within your project
   • customer_first_name—customer first name
   • customer_last_name—customer last name
   • customer_email—customer email address
   • payment_currency—payment currency in ISO-4217 alpha-3 format
   • payment_amount—purchase amount in major currency units without any fractional part.

     If the currency does have minor units (that is, the number of digits for minor currency units is not zero), then you must set this parameter to the amount in minor currency units without any decimal point or comma . For the information on whether the currency has any minor units, see Currency codes.

2. If you need to have payment form displayed with the Bank transfers in Vietnam method preselected, set the force_payment_method parameter to bank-transfer-vietnam.
3. If required, you can also add any other additional parameters Payment Page supports. For information about all parameters available in the Bank transfers in Vietnam payment method, see Payment Page invocation parameters.
4. After you specify all the parameters you need, you are required to create the signature for the request. For instructions on how to sign a payment request, see Signature generation and verification.

Here is an example of data from a request for Payment Page opening:

EPayWidget.run(
    { project_id: 214,
      payment_id: 'X03936',
      customer_id: 'customer_123', 
      customer_first_name: 'John',
      customer_last_name: 'Doe',
      customer_email: 'example@email.com',
      payment_amount: 300000, 
      payment_currency: 'VND', 
      signature: "kUi2x9dKHAVNU0FYldJrxhRLCvhtT4DqtVUkDJrOcZzUCwX6R\/ekpZhkIQg=="
    }
)

Callback format

The Bank transfers in Vietnam method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks in Payment Page.

Please contact your Monetix key account manager to confirm whether this option is available to you.

General information

In the Bank transfers in Vietnam method, 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 Monetix URL.
2. Redirect customer to the provider service.
3. Get a callback with the payment result from the payment platform.

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

The sections that follow discuss in more details the request format and the Gate parameters to use in the Bank transfers in Vietnam 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. For the general information about using the Gate API, see API Description.

Request format

1. You perform purchases by sending the request to the /v2/payment/bank-transfer/vietnam/sale endpoint by using POST (HTTP) method. This is a group of endpoints for bank transfer payments: /v2/payment/bank-transfer/{payment_method}/sale
2. The following objects and parameters must be specified in any request:
   • general—object with general request identification information:
     • project_id—the project ID obtained from Monetix
     • payment_id—payment ID unique within the project
     • signature—signature created after you specify all the required parameters. For more information about signature generation, see Signature generation and verification.
   • customer—object with customer information:
     • id—the unique ID of the customer within your project
     • ip_address—customer device IP
     • first_name—customer first name
     • last_name—customer last name
     • email—customer email address
   • account—object with customer account information:
     • bank_id—bank identifier. This parameter may not be mandatory. Refer to you Key Account Manager at Monetix for details.
   • payment—object with purchase information:
     • amount—purchase amount in major currency units without any fractional part.

       If the currency does have minor units (that is, the number of digits for minor currency units is not zero), then you must set this parameter to the amount in minor currency units without any decimal point or comma . For the information on whether the currency has any minor units, see Currency codes.

     • currency—code of the purchase currency in the ISO-4217 alpha-3 format
   • return_url—object with the information where to redirect the customer to when the payment is completed or prematurely terminated by the customer:
     • success—the URL to redirect the customer to after the payment is successfully completed. This parameter may not be mandatory. Refer to you Key Account Manager at Monetix for details.
     • decline—URL for redirecting when payment fails. This parameter may not be mandatory. Refer to you Key Account Manager at Monetix for details.
3. The following parameter with the return URL is optional, but we strongly advise you to specify it in the request to provide your customer a better user experience. If you don't specify any parameters of the return_url object in the request, by default Gate will redirect the customer to the URL specified in your project in Monetix.
   • return_url—object with the information where to redirect the customer to when the payment is completed or prematurely terminated by the customer:
     • return—the URL to redirect the customer to when they prematurely terminate the payment. This URL is also used if the success and decline parameters are not specified in the request
4. If required, you can add any other additional parameters Gate supports.

Here is an example of data from a purchase request in the Bank transfers in Vietnam method.

{
    "general": {
      "project_id": 1234,
      "payment_id": "payment_47",

      "decline": "https://example.com/decline/",
      "return": "https://example.com/return/"
    }  
}

Formats of the customer redirection data

To redirect a customer from the web service to the bank site, you are required to accept a callback from the payment platform with a redirect_data object which contains the URL for redirecting the customer in the url parameter and the data to be sent in the request body in the body parameter. Use these parameters to open the web page by using the HTML method specified in the method parameter.

The following is the callback fragment containing the redirection data.

"redirect_data": {
    "method": "GET",
    "body": [],
    "encrypted": [],
    "url": "http://example.com/redirect"
  }

Callback format

The Bank transfers in Vietnam method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks in Gate.

General information

In the Bank transfers in Vietnam method, 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 Monetix URL.
2. Display the payment instructions to the customer.
3. Get a callback with the payment result from the payment platform.

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

The sections that follow discuss in more details the request format and the Gate parameters to use in the Bank transfers in Vietnam 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. For the general information about using the Gate API, see API Description.

Request format

1. You perform purchases by sending the request to the /v2/payment/bank-transfer/vietnam/sale endpoint by using POST (HTTP) method. This is a group of endpoints for bank transfer payments: /v2/payment/bank-transfer/{payment_method}/sale
2. The following objects and parameters must be specified in any request:
   • general—object with general request identification information:
     • project_id—the project ID obtained from Monetix
     • payment_id—payment ID unique within the project
     • signature—signature created after you specify all the required parameters. For more information about signature generation, see Signature generation and verification.
   • customer—object with customer information:
     • id—the unique ID of the customer within your project
     • ip_address—customer device IP
     • first_name—customer first name
     • last_name—customer last name
     • email—customer email address
   • payment—object with purchase information:
     • amount—purchase amount in major currency units without any fractional part.

       If the currency does have minor units (that is, the number of digits for minor currency units is not zero), then you must set this parameter to the amount in minor currency units without any decimal point or comma . For the information on whether the currency has any minor units, see Currency codes.

     • currency—code of the purchase currency in the ISO-4217 alpha-3 format
   • account—object with customer account information:
     • bank_id—bank identifier. This parameter may not be mandatory. Refer to you Key Account Manager at Monetix for details.
3. If required, you can add any other additional parameters Gate supports.

Here is an example of data from a purchase request in the Bank transfers in Vietnam method.

    "general": {
      "project_id": 211,
      "payment_id": "payment_id",
      "signature": "PJkV8ej\/UG0Di8NN5e7cV+VHq3oXW\/9MTO8yJA=="
    },
    "payment": {
      "amount": 30000,
      "currency": "VND"
    },
    "customer": {
      "id": "123",
      "ip_address": "198.51.100.47",
      "first_name": "John",
      "last_name": "Doe",
      "email": "example@email.com"
    }
}

Format of data for displaying the payment instruction

Before displaying the screen with payment instructions to the customer, you must accept a callback from the payment platform with the payment data in the in the display_data array—only after this you can display the screen with payment instructions to the customer.

There are two options the way the display_data array is structured. Both of them are described below. Refer to you Key Account Manager at Monetix for details on which one is relevant for you.

Option 1

Each element of the display_data array contains the following parameters:

• type—element type (always add_info)
• title—the name of the payment instruction data, can take the following values:
  • bank_name—name of the payment recipient bank
  • number—account number of the payment recipient
  • fullName—full name of the payment recipient
  • branch—branch name of the payment recipient bank
  • content—payment description
  • swiftCode—SWIFT code of the payment recipient bank
• data—payment instruction data

Here is a sample of a callback with a display_data object.

"display_data": [
    {
        "type": "add_info",
        "title": "bankName",
        "data": "Wooribank Việt Nam"
    },
    {
        "type": "add_info",
        "title": "number",
        "data": "902014188917"
    },
    {
        "type": "add_info",
        "title": "fullName",
        "data": "PAYME MNTX"
    },
    {
        "type": "add_info",
        "title": "branch",
        "data": "Hà Nội"
    },
    {
        "type": "add_info",
        "title": "content",
        "data": "TT 8575"
    },

        "type": "add_info",
        "title": "swiftCode",
        "data": "HVBKVNVXXXX"
    }
]

Callback format

The Bank transfers in Vietnam method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks in Gate.

Please contact your Monetix key account manager to confirm whether this option is available to you.

The following is the example of a callback with an information about successful 300,000 VND purchase made in the 1234 project.

General information

You can perform test purchases with the Bank transfers in Vietnam payment method by using Payment Page and Gate.

To perform test purchases, you'll need the test project ID and the secret key to it. To get them, please contact the technical support team at support@monetix.pro and then contact your Monetix key account manager to set up a test environment to work with the Bank transfers in Vietnam payment method.

When performing test payments, keep in mind that:

• your requests must contain the test project ID
• the payment currency that you send in requests can be only VND
• random values may be used as the payment ID and in the parameters with customer information
• the interface of the test checkout page may be different from the production one.

Test payments statuses

To receive one of the following statuses in the callback with the test purchase result, use a particular value for the purchase amount in the request:

• 400 and 404—to receive a callback with the decline status
• any other value—to receive a callback with the success status

Testing purchase by using Payment Page

To perform a test purchase by using Payment Page:

1. Send a request for purchase through Payment Page to the payment platform.
2. Choose a payment method on the test checkout page. If you've passed the force_payment_method parameter with the bank-transfer-vietnam value in the request, you won't have to choose the payment method.
3. Specify a random first name and last name in the data entry fields. The payment instructions will be displayed to you after.
4. Accept a callback with information about the test purchase result.
5. Wait a few seconds until the result of the test purchase is displayed to you on the test checkout page.

See the detailed information about purchase processing through Payment Page in the Bank transfers in Vietnam payment method in the Purchase by using Payment Page section.

Testing purchase by using Gate

To perform a test purchase by using Gate:

1. Send a request for performing a test purchase to the payment platform.
2. Accept a callback with the data for displaying payment instructions. Your system will display the payment instructions to you after.
3. Accept a callback with information about the test payment result.
4. Wait a few seconds until your system shows you the result of the test purchase.

See the detailed information about purchase processing through Gate in the Bank transfers in Vietnam payment method in the Purchase by using Gate section.

As with other payment methods Monetix offers, when using this method, you have several options to analyze the information about payments and operations.

You can load and analyze all the necessary information in Dashboard (dash-light.trxhost.com), for instance you can use the analytic panels in the Analytics section for this purpose.

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 format by using the tools in the Reports section. You can perform export as a one-time or regular download of data to your local computer.
• 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 means of sending requests to the /operations/get endpoint.

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