Integrating Multiple PGs

Last updated 2 years ago

Set up multiple PGs in the i'mport Admin console and open a payment window for the desired payment method.

1. Configure authenticated payment (general)

Go to to set the default PG that is used as the default param.pg value when you call to open the payment window. The default value is used when the pg value is missing or invalid.

2. Add PG for subscription payment (for non-authenticated/PG payment window)

3. Add PG for simple payment (Kakao Pay)

Repeat step 2 to add PG setting for Kakao Pay.

Open PG's payment window

  • { PG code }

  • { PG code }.{ PG Merchant ID }

Assume that we have added 3 PG settings as follows:

PG
Merchant ID
Pay Type
Default PG

KG INICIS

MID-a (example)

General

O

KG INICIS

MID-b (example)

Subscription

X

Kakao Pay

MID-c (example)

Simple

X

Of the previously added PG settings, Kakao Pay can be identified just with the PG service code. Set kakaopay in the pg property for the Kakao Pay payment request as follows:

client-side
 IMP.request_pay({
    pg : "kakaopay",  //Open Kakao Pay payment page
    amount : 1000,
    name : "Sample order",
    buyer_name : "Buyer",
    buyer_email : "buyer@iamport.kr"
  });

Of the previously added PG settings, KG INICIS (general) and KG INICIS (subscription) have the same PG service code. Hence, you need to set pg to a value that combines the service code with the Merchant ID, { PG Code }.{ PG Merchant ID }.

JavaScript
IMP.request_pay({
    pg : "html5_inicis.MID-a",  // Call KG INICIS general payment window (merchant ID: MID-a)
    amount : 1000,
    name : "Sample order",
    buyer_name : "Buyer",
    buyer_email : "buyer@iamport.kr"
  });
JavaScript
IMP.request_pay({
    pg : "html5_inicis.MID-b",  // Call KG INICIS subscription payment window (merchant ID: MID-b)
    amount : 1000,
    name : "Sample order",
    buyer_name : "Buyer",
    buyer_email : "buyer@iamport.kr"
  });

Matching priority for PG

After acquiring a separate Merchant ID (MID) for subscription (non-authenticated) payment from the PG, use it to add the PG from the .

To open a PG's payment window, call IMP.request_pay by specifying the PG that is already configured in Admin console in the param.pg property.

The can have the following format:

finds the setting that matches the pg value in the order the PG settings are shown in the Admin console. It opens the payment window for the first matching PG setting.
