Purchase API - Create Payment Intent #

1. API Overview #

Purpose #

This API initializes a payment intent to start the payment process. It supports various payment methods including card, bank transfer, installment, and e-wallet. You can choose an integration method that suits your environment: either a redirect method using the EBP-provided payment URL (paymentUrl) or a direct integration method using the PG response data (pgResponse). After creating a payment intent, the user proceeds with the payment directly through the PG depending on the integration method, and EBP then receives the result to send a Webhook or the merchant calls the Payment Creation API to finalize the transaction.

[!INFO] Billing Account Creation
A billing account is automatically created in the system based on the combination of Store ID (X-Store-Id) and User Number (userNo) when a user registers a token or requests a payment for the first time, without any separate sign-up process.

After creating a payment intent, if the user completes authentication via the payment method, EBP sends a Webhook to the store to notify the result.
Detailed documentation for the Webhook can be found at the link below.

Payment Flow and Field Usage Guide:

  1. status: Current status of the payment resource. The client checks this value to determine the progress and final success of the payment.
  2. instructions.nextStep: Indicates that the control to proceed with the payment belongs to the client when the status is ACTION_REQUIRED.
  3. instructions.requiresClientAction and clientAction: Indicates whether additional client actions are required. If requiresClientAction is true, the client must perform the specified action (e.g., Redirect to the provided paymentUrl or Directly call the SDK using PG response data) by checking clientAction.type.
  4. data.paymentUrl: URL provided by EBP by wrapping the PG's payment page. It is used when you want to handle the payment simply through redirection without complex PG integration logic. (Mainly used when clientAction.type is REDIRECT_TO_HPP)
  5. instructions.completionMethod: Specifies the subject and path for final closure of the payment process.
    • WEBHOOK: After the client action is completed, EBP receives the PG webhook and automatically processes the payment completion. Since a result webhook is subsequently sent to the store, the client moves to the result page and waits for processing.
    • API: The process finally ends only after the client directly secures authentication information and calls the EBP Payment Creation API.
  6. instructions.requiresFollowUpApi and followUpApi: Indicates whether a follow-up API call is mandatory after the client action. If requiresFollowUpApi is true, the client must directly call the final Payment Creation API, etc., referring to followUpApi.method and url.
  7. data.paymentContext: A value containing encrypted order and session information. If the completionMethod is API (or if a follow-up API call is required), this value must be included in both the Header (X-EBP-Context) and the Body (paymentContext) when calling the subsequent Payment Creation API.

4. Response Post-processing Guide (Next Steps) #

After calling the Create Payment Intent API, if the response status is ACTION_REQUIRED and instructions.nextStep is CLIENT_ACTION, the client must transition the screen or initialize the PG SDK so that the user can proceed with the payment based on the provided data.

Depending on the store's environment and requirements, you can choose between the Redirect Integration (HPP Wrapping) and Direct Integration (Direct PG SDK/UI Rendering) methods.

4.1 Redirect Integration (Simple Integration) #

This is the simplest method where the user is moved to a payment page provided by EBP to process the payment. The store does not need to directly implement complex SDK integration logic for each PG provider.

  • Target Field: data.paymentUrl
  • Processing Method: The received paymentUrl includes an encrypted context required for payment authentication as a query parameter. The store can simply redirect to this URL using the GET method.

Integration Example (Common) #

Use the paymentUrl received from the Create Payment Intent API response as follows:

1. HTML Setup (Virtual Form for Data Transmission)

<!-- The method must be set to POST. -->
<form id="ebp-redirect-form" method="POST"></form>

2. Javascript Processing Example

// 1. Receive response data from the EBP Create Payment Intent API
const { paymentUrl } = response.data; 

// 2. Set paymentUrl to the form action
const form = document.getElementById("ebp-redirect-form"); 
form.action = paymentUrl;

// 3. Submit the form (Redirect to payment page)
form.submit();

Notes:

  • Since the paymentUrl already contains the payment context (paymentContext), there's no need to create separate input fields inside the form or manually assemble the data. The browser will maintain the URL's query string while sending the POST request, and EBP will receive it to securely construct the PG provider's payment screen.
  • When using the redirect method via paymentUrl, EBP will directly finalize all authentication and authorization processes, even if the response data contains follow-up API call flags (requiresFollowUpApi) or details (followUpApi). The store only needs to verify the result through webhooks or the final redirect URL without calling a separate Payment Creation API.

4.2 Direct Integration (Custom Integration) #

This method is used when you want to directly render UI components (Drop-in) provided by the PG provider within the store's existing payment screen.

  • Target Field: Authentication information per PG provider within data.pgResponse.data
  • Processing Method: Use the Key, Token values, etc., returned for each PG provider to initialize the PG SDK and proceed with the payment in the frontend environment.

Worldpay Direct Integration Example #

Worldpay uses the provided referenceUrl to initialize the PG SDK.

1. HTML Setup

<!-- WorldPay Web Components SDK -->
<script src="https://payments.worldpay.com/resources/hpp/integrations/embedded/js/hpp-embedded-integration-library.js"></script>

<!-- Container where the Worldpay UI will be rendered -->
<div id="worldpay-container"></div>

2. Javascript Processing Example

const { referenceUrl } = response.data.pgResponse.data;

const customOptions = {
    url: referenceUrl,
    type: "iframe",
    inject: "onload",
    target: "worldpay-container",
    accessibility: true,
    language: "en",
    country: "GB",
    successURL: response.data.successUrl,
    cancelURL: response.data.failureUrl,
    failureURL: response.data.failureUrl,
    errorURL: response.data.failureUrl
};

if (customOptions.url) {
    const libraryObject = new WPCL.Library();
    libraryObject.setup(customOptions);
}

Checkout.com Direct Integration Example #

Checkout.com uses the provided publicKey and paymentSession object to mount the Flow UI component.

1. HTML Setup (Load SDK and Define Mount Point)

<!-- Checkout.com Web Components SDK -->
<script src="https://checkout-web-components.checkout.com/index.js"></script>

<!-- Container where the Checkout.com UI will be rendered -->
<div id="checkout-container"></div>

2. Javascript Processing Example

const { publicKey, paymentSession } = response.data.pgResponse.data;

// 1. Initialize Checkout Web SDK
const checkout = await CheckoutWebComponents({
    publicKey: publicKey,
    environment: 'sandbox', // or 'production'
    paymentSession: paymentSession, // Pass the entire object
    onPaymentCompleted: (component, paymentResponse) => {
        window.location.href = response.data.successUrl;
    },
    onError: (component, error) => {
        console.error("Checkout Error:", error);
    }
});

// 2. Create and mount the Flow component
const flowComponent = checkout.create('flow');
flowComponent.mount('#checkout-container');

Omise Card Direct Integration Example #

For credit card payments, a one-time token is generated using the publicKey, and then the EBP Payment Creation API is called with that token information.

1. HTML Setup

<!-- Load Omise.js SDK -->
<script type="text/javascript" src="https://cdn.omise.co/omise.js"></script>

<!-- Payment execution button -->
<button id="omise-card-btn">Pay with Card</button>

2. Javascript Processing Example

const { publicKey, authRequestId, authSignature, paymentHeaderContext, paymentContext, amount, currency } = response.data.pgResponse.data;

// Configure Omise SDK
OmiseCard.configure({ publicKey: publicKey });

document.getElementById('omise-card-btn').onclick = () => {
    OmiseCard.open({
        amount: amount,
        currency: currency,
        onCreateTokenSuccess: async (token) => {
            const paymentBody = {
                authRequestId,
                authSignature,
                paymentContext,
                paymentMethod: "CARD",
                paymentInstrumentId: token,
                paymentInstrumentType: "ONE_TIME_TOKEN"
            };

            const host = 'https://devkic-payapi.nebp.lge.com/';
            
            // Call EBP Payment Creation API
            const chargeResponse = await fetch(`${host}/api/v2/payments`, {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                    'X-EBP-Context': paymentHeaderContext
                },
                body: JSON.stringify(paymentBody)
            });

            if (!chargeResponse.ok) throw new Error("Payment API call failed");
            const result = await chargeResponse.json();
            
            // Redirect to authorizeUri if 3DS authentication is required
            const authorizeUri = result.data?.pgResponse?.data?.authorizeUri;
            if (authorizeUri) {
                window.location.href = authorizeUri;
            } else if (result.resultCode === "0") {
                window.location.href = response.data.successUrl;
            }
        }
    });
};

Omise Installment (Source) Direct Integration Example #

For source-based payments like installments, a one-time source ID is generated via createSource before the payment request.

1. HTML Setup

<!-- Load Omise.js SDK -->
<script type="text/javascript" src="https://cdn.omise.co/omise.js"></script>

<!-- Payment execution button -->
<button id="omise-installment-btn">Pay with Installment</button>

2. Javascript Processing Example

const { publicKey, authRequestId, authSignature, paymentHeaderContext, paymentContext, installmentSource, installmentTerm, amountDecimal, currency } = response.data.pgResponse.data;

Omise.setPublicKey(publicKey);

document.getElementById('omise-installment-btn').onclick = () => {
    const sourceParams = {
        type: installmentSource,
        amount: Number(amountDecimal), // Use amount with decimals for source creation
        currency: currency,
        installment_term: installmentTerm
    };

    Omise.createSource(sourceParams.type, sourceParams, async (statusCode, res) => {
        if (statusCode === 200) {
            const paymentBody = {
                authRequestId,
                authSignature,
                paymentContext,
                paymentMethod: "INSTALLMENT",
                paymentInstrumentId: res.id,
                paymentInstrumentType: "ONE_TIME_SOURCE"
            };

            const host = 'https://devkic-payapi.nebp.lge.com/';

            // Call EBP Payment Creation API
            const paymentResponse = await fetch(`${host}/api/v2/payments`, {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                    'X-EBP-Context': paymentHeaderContext
                },
                body: JSON.stringify(paymentBody)
            });

            const result = await paymentResponse.json();
            
            // Redirect to authorizeUri if 3DS authentication is required
            const authorizeUri = result.data?.pgResponse?.data?.authorizeUri;
            if (authorizeUri) {
                window.location.href = authorizeUri;
            } else if (result.resultCode === "0") {
                window.location.href = response.data.successUrl;
            }
        }
    });
};
