KG Mobilians payment window integration guide

1. Configure KG Mobilians PG Settings

Refer to the KG Mobilians settings page to configure the PG settings.

2. Request payment

To open the payment window, call JavaScript SDK IMP.request_pay(param, callback).

In PC browsers, callback is invoked after calling IMP.request_pay(param, callback). In mobile browsers, the page is redirected to m_redirect_url.

Authenticated payment request

Javascript SDK

IMP.request_pay({
    pg : 'mobilians',
    pay_method : 'phone',
    merchant_uid : '{Merchant created Order ID}', // Example: order_no_0001

Non-authenticated payment request

To open non-authenticated payment window, specify the customer_uid parameter. After getting a billing key from this window, you can request payment using the billing key.

Javascript SDK

IMP.request_pay({
    pg : 'mobilians',
    pay_method : 'phone',
    merchant_uid : '{Merchant created Order ID}', // Example: issue_billingkey_monthly_0001
    name : 'Initial billing key request',
    amount : 0, // For display purpose only (no payment approval).
    customer_uid : '{Unique ID for the card (billing key)}', // Required (Example: gildong_0001_1234)
    buyer_email: "[e-mail]",
    buyer_name: "John Doe",
    buyer_tel : '02-1234-1234',
    m_redirect_url : '{redirect URL}' // Example: https://www.my-service.com/payments/complete/mobile (for mobile only)
}, function(rsp) {
	if ( rsp.success ) {
		alert('Success');
	} else {
		alert('Failed');
	}
});

• To request non-authenticated payment, you must set the MID info issued by KG Mobilians in the Admin console.

• KG Mobilians does not process the payment when issuing the billing key even if you specify an amount.

• Subsequent payments using the billing key must be for the same amount and on the same day as the initial payment on monthly basis.

Key parameter description

pg *** **string

PG code

• If not specified and this is the only PG setting that exists, default PG is automatically set.

• If there are multiple PG settings, set to mobilians.[MID].

customer_uid *** **string

Credit card billing key

Billing key to be mapped 1:1 with the user-entered credit card information.

amount *** **Integer

Payment amount

Amount to display in the payment window, but actual payment approval is not processed. (To request payment, use the REST API with the customer_uid.)\

Request payment with billing key (customer_uid)

After successfully getting the billing key, the billing key is stored on the i'mport server mapped 1:1 with the specified customer_uid. For security reasons, the server cannot directly access the billing key. Subsequent payments can be requested by calling the non-authenticated payment request REST API with the customer_uid as follows:

sever-side

curl -H "Content-Type: application/json" \   
     -X POST -d '{"customer_uid":"your-customer-unique-id", "merchant_uid":"order_id_8237352", "amount":3000}' \
     https://api.iamport.kr/subscribe/payments/again

Non-authenticated API request

Not supported.
