DuitNow

Interaction diagram

Payment processing by using the DuitNow payment method requires merchant web service, one of Monetix interfaces, and the Monetix payment platform, as well as provider's technical facilities.

Operations support

	Interfaces			Amounts, MYR		Times
	Payment Page	Gate	Dashboard	minimum	maximum	basic	threshold
Purchases				1.00	30,000.00	1 minute	48 hours

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 DuitNow method, to perform a purchase, you need to redirect customer to the provider service.

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

Special payment processing considerations

If the payment amount is exactly the same as the amount of one of the currently processed payments, then due to some special aspects of the provider operation, the payment platform may increase the payment amount by 0.01 to 0.99 MYR (but does not necessarily do so). This is sometimes required to distinguish between the current payment and the other ongoing payments with the same amount. The platform makes its best to avoid increasing the payment amount, if this is possible.

If number of the currently processed payments is so large that there are no more free slots in the 0,01 to 0,99 MYR range, then the payment platform declines the current request and all subsequent ones until processing of at least one of the current payments with the same amount is complete.

If the payment platform is forced to increase the payment amount, it responds to the web service with a callback with the new amount.

Here is an example of how the payment platform may behave when receiving two requests for payment with the same amount:

1. The payment platform accepts the first request for payment of 15.00 MYR. This is the first request with this amount, therefore the payment platform does not change its amount and starts processing a 15,00 MYR payment.
2. The payment platform accepts the second request for payment of 15.00 MYR.
3. Since the payment with the amount of 15.00 MYR is already being processed, the payment platform changes the amount of the second payment to 15.01 MYR and proceeds with this amount.

General information

In the DuitNow method, when processing a purchase by using Payment Page, the merchant web service sends a request with all the required parameters and signature to the Monetix URL and accepts the callback with the payment result from the payment platform. When opening Payment Page, you can have Payment Page opened with the DuitNow method pre-selected. (For more information about pre-selecting payment methods, see in Preselecting payment methods.)

The full sequence of the purchase workflow is provided below.

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

Request format

There are several things you need to consider when dealing with purchase requests in the DuitNow 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 you 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—payment amount in minor currency units without any decimal point or comma except for cases where the currency does not have any minor currency units. If the currency has no minor units (that is, the number of digits for minor currency units is zero), then you must set this parameter to the amount in the major currency units. 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 DuitNow method pre-selected, set the force_payment_method parameter to the code on the duitnow-wallet payment method.
3. You can also add any other additional parameters Payment Page supports. For more information about parameters supported by Payment Page, see Payment Page invocation parameters.
4. After you specify all the parameters you need, you need to generate signature for the request. For instructions on how to sign payment requests, see Signature generation and verification.

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

EPayWidget.run(
    {
        project_id: 1234, 
        payment_id: 'payment_47',
        customer_id: 'customer_123',
        customer_first_name: 'John',
        customer_last_name: 'Doe',
        customer_email: 'example@email.com',      
        payment_currency: 'MYR',
        payment_amount: 50000
        signature: "kUi2x9dKHAVNU0FYldJrxh4yo+52Kt8KU+Y19vySO\/RLUkDJrOcZzUCwX6R\/ekpZhkIQg=="
    }
)

Callback format

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

The following is an example of a callback with an information about successful 500.00 MYR purchase in the 1234 project.

General information

In the DuitNow method, the merchant web service is required to do the following when processing a purchase by using Gate:

1. Send request with all the required parameters and signature to the Monetix URL.
2. Redirect the customer to the provider service.
3. Accept the 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 DuitNow payment method and provide the information about the format of callbacks with purchase results. For the general information on how to use the Gate API, see API Description.

Request format

There are several things you need to consider when dealing with purchase requests in the DuitNow method:

1. You initiate purchase request by sending a request to the /v2/payment/wallet/duitnow/sale endpoint by using HTTP method POST. This endpoint belongs to the following group of endpoints for payments by using e-wallets: /v2/payment/wallet/{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 you 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 minor currency units without any decimal point or comma except for cases where the currency does not have any minor currency units. If the currency has no minor units (that is, the number of digits for minor currency units is zero), then you must set this parameter to the amount in the major currency units. For the information on whether the currency has any minor units, see Currency codes.
     • currency—code of purchase currency in the ISO-4217 alpha-3 format
3. The following parameters with the return URLs are optional, but we strongly advise you to specify them 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:
     • success—the URL to redirect the customer to after the payment is successfully completed
     • decline—the URL to redirect the customer to after the payment is declined
     • 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 (optional) parameters Gate supports.

Here is an example of data from a purchase request in the DuitNow method.

{
    "general": {
        "project_id": 1234,
        "payment_id": "payment_47",
        "signature": "PJkV8ej\/UG0Di8hTng6JvC7vQsaC6tajQVVfBaNIipTv+AWoXW\/9MTO8yJA=="
    },
    "customer": {
        "id": "customer_123",
        "ip_address": "198.51.100.47",
        "first_name": "John",
        "last_name": "Doe",
        "email": "example@email.com"
    },
    "payment": {
        "amount": 50000,
        "currency": "MYR"
    },
    "return_url": {
        "success": "https://example.com/success/",
        "decline": "https://example.com/decline/",
        "return": "https://example.com/return/"
    }
}

Format of customer redirection data

After receiving and processing your purchase request, the payment platform sends a callback to your web service containing the data to redirect the customer to the provider service.

To redirect the customer, use the values of the following parameters in the redirect_data object:

• url—the URL to redirect the customer to
• body—the data to be sent in the request body
• method—the HTTP method to get an HTML page of the website (for example, POST or GET)
• encrypted—this is the service parameter. Ignore the data it contains.

Here is an example of a piece of callback containing the data to redirect the customer.

"redirect_data": {
    "method": "POST",
    "body": {
        "example_parameter_1": "value_1",
        "example_parameter_2": "value_2"
    },
    "encrypted": [],
    "url": "https://example.com/redirect"
}

Callback format

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

General information

You can perform test purchases with the DuitNow 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, contact the technical support team at support@monetix.pro.

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 MYR
• 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:

• decline—when using 40000 or 40400 amount
• success—when using any amount other than those mentioned above

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 duitnow-wallet value in the request, you won't have to choose the payment method.
3. Click the Success or Decline button (the relevant button will be displayed depending on the amount sent in the request).
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 DuitNow 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 redirection data.
3. Go to the received URL and click the Success or Decline button (the relevant button will be displayed depending on the amount sent in the request).
4. Make sure that the test purchase confirmation page is displayed to you.
5. Accept a callback with information about the test payment result.

See the detailed information about purchase processing through Gate in the DuitNow 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.
