Non-hosted local payment is suitable for merchants who build their own checkout page. You need to display the available payment methods on the checkout page, let the merchant server call Create Order and Pay to create the payment order, and then continue the payment flow according to action in the response. The final payment result must be confirmed through Payment Notification or Transaction Query.

Supported Features

Pay-in (Immediate Capture)	Authorization (Auth then Capture)	Refund & Partial Refund	重新支付	Token凭证支付	线下扫码支付

Solution Overview

In this model, the shopper starts payment on the merchant page. The merchant server calls Create Order and Pay to create the local payment order. When the response returns action, the merchant front end continues the shopper payment flow according to action. After the shopper completes payment, the merchant server confirms the final result through asynchronous notification or active query.

Payment Flow

Flow summary:

The shopper chooses a local payment method on the merchant checkout page.
The merchant front end submits order information, payment method, and device information to the merchant server.
The merchant server calls Create Order and Pay to create the payment order.
PingPongCheckout returns the synchronous response. If the shopper needs to continue, the response includes action.
The merchant front end continues the shopper payment flow according to action. The following steps use redirect-based local payment methods as the example.
After the shopper completes payment, PingPongCheckout pushes the payment result through notificationUrl.
If the merchant does not receive the notification for a long time, it should actively call Transaction Query to confirm the final result.

Note

If the shopper returns from the local payment page to payResultUrl, it only means the shopper is back on the merchant page. It does not mean the payment has succeeded. Order posting, fulfillment, or entitlement delivery must rely on the server-side asynchronous notification or transaction query result.

API List

Non-hosted local payment typically involves the following APIs and notifications:

Phase	Type	Document	Required	Purpose
Payment Creation	API	Create Order and Pay	Required	Create the local payment order and get payment continuation parameters
Payment Result	Notification	Payment Notification	Required	Receive the final payment result and update the merchant order status
Payment Result	API	Transaction Query	Recommended	Actively verify the transaction status when notifications are delayed, not received, or need fallback confirmation
Refund	API	Refund Request	As needed	Initiate a refund for a successful local payment transaction
Refund	Notification	Refund Notification	Recommended	Receive the refund result and update the refund status
Refund	API	Refund Query	Recommended	Actively confirm the refund status when notifications are delayed, not received, or during reconciliation

Integration Preparation

Before you start development, make sure the following items are ready.

Item	Description
Account information	`clientId` and `accId` have been obtained, and the shop status is confirmed to be able to transact
Payment method	The target local payment method has been enabled, and its supported countries, currencies, amount range, and refund capability have been confirmed
Signing capability	Request signing has been completed according to the Signature Guide, and all request parameters participate in signing
Signature verification capability	The merchant can verify the `sign` in PingPongCheckout responses and asynchronous notifications
Notification URL	A public `notificationUrl` is ready to receive asynchronous payment notifications
Result page URL	`payResultUrl` is ready for redirect-based payment methods to return the shopper to the merchant page
Order status handling	The merchant system stores `merchantTransactionId`, `requestId`, `transactionId`, and order status, and supports idempotent updates

Tip

Different local payment methods may require extra fields such as customer, goods, billingAddress, shippingAddress, or a specific device.orderTerminal. Always follow the target payment method page and the Create Order and Pay parameter table.

Note

notificationUrl must be a complete public URL. Do not use localhost, 127.0.0.1, or an internal IP, and do not append query parameters to the URL.

Integration Steps

Complete the integration in the following steps:

Step 1: Display available payment methods
Step 2: Create the payment order
Step 3: Continue the payment flow according to action
Step 4: Get the final payment result

Step 1: Display available payment methods

Display the payment method name and identifier that you plan to support on the shopper checkout page, so the shopper can choose based on preference and scenario. The payment method list page should be implemented by your own front end.

When displaying payment methods, we recommend filtering at least by the following conditions:

Condition	Handling recommendation
Trading country	Use the order country or shopper checkout country to match `tradeCountry`
Currency	Use the currency supported by the payment method. Refer to Transaction Currency for amount precision
Terminal	Prepare `device.orderTerminal` for Web, WAP, App, and other scenarios
Payment method type	Write the shopper-selected payment method into `paymentMethod.type`

Step 2: Create the payment order

Call Create Order and Pay to create the payment order. You need to collect the shopper payment method, order information, device information, payment amount, and then submit the payment request from the merchant server.

Payment request key parameters:

Parameter	Required	Description
`clientId`	M	PingPong merchant ID
`accId`	M	PingPong shop ID
`signType`	M	Signature type, supports `MD5` and `SHA256`
`sign`	M	Request signature
`version`	M	API version, currently fixed at `1.0`
`bizContent.captureDelayHours`	M	Local payment uses `0`, meaning immediate capture
`bizContent.amount`	M	Transaction amount
`bizContent.currency`	M	ISO 4217 three-letter transaction currency
`bizContent.merchantTransactionId`	M	Merchant order ID, unique order identifier
`bizContent.requestId`	M	Payment request ID, globally unique
`bizContent.tradeCountry`	M	Trading country, using ISO 3166-1 alpha-2 code
`bizContent.shopperIP`	M	Shopper IP
`bizContent.paymentMethod.type`	M	Local payment method selected by the shopper
`bizContent.goods`	M	Goods information, including at least `goods[].name`, `goods[].unitPrice`, `goods[].number`, and `goods[].imgUrl`
`bizContent.device.orderTerminal`	M	Order terminal. `01` mobile browser (WAP), `02` PC browser (WEB), `04` iOS App, `05` Android App
`bizContent.notificationUrl`	O	Payment result notification URL, recommended
`bizContent.payResultUrl`	C	Merchant result page URL for redirect-based local payment methods
`bizContent.merchantUserId`	O	Merchant-side unique user ID
`bizContent.customer.email`	C	Shopper email. Required for physical goods merchants; for virtual goods merchants, one of `email` or `merchantUserId` is required
`bizContent.customer.phone`	C	Shopper phone number. Required by some local payment methods. Follow the specific payment method requirements

For full parameter details, see Create Order and Pay.

      }
    ],
    "device": {
      "orderTerminal": "02"
    }
  }
}

Tip

For readability, the examples in this guide expand bizContent as a JSON object. In real requests, process bizContent and the signature according to Create Order and Pay and the Signature Guide.

Response key fields:

Parameter	Description
`code`	Public response code. `000000` means the request is processed successfully
`description`	Public response description
`bizContent.transactionId`	PingPong transaction ID
`bizContent.merchantTransactionId`	Merchant order ID
`bizContent.requestId`	Payment request ID
`bizContent.status`	Transaction status
`bizContent.action`	Payment continuation parameters returned when the shopper needs to continue

Response example:

{
  "accId": "2023042011040310224447",
  "clientId": "2023042011040310224",
  "code": "000000",
  "description": "Transaction succeeded",
  "sign": "{{Sign}}",
  "signType": "SHA256",
  "bizContent": {
    "transactionId": "2026061050010001",
    "merchantTransactionId": "ORDER_202606100001",
    "requestId": "REQ_202606100001",
    "amount": "1000.000000",
    "currency": "THB",
    "status": "PROCESSING",
    "paymentMethod": {
      "type": "TrueMoney Wallet"
    },
    "action": {
      "type": "PAYMENT_REDIRECT_URL",
      "paymentRedirectUrl": "https://sandbox-acquirer-static.pingpongx.com/payment/apm.html?token=example"
    },
    "payResultUrl": "https://www.example.com/checkout/result",
    "transactionTime": "1781080205000",
    "captureDelayHours": 0
  }
}

bizContent.status in the synchronous response may return the following values:

`bizContent.status`	Meaning	Next action
`SUCCESS`	The synchronous response already succeeded	The merchant server can update the order status, but we still recommend using asynchronous notification or query to ensure final consistency
`FAILED`	Payment failed	Ask the shopper to choose another payment method or retry
`PROCESSING`	Payment is in progress	If `action` is returned, continue with Step 3 and wait for the asynchronous notification or actively query the transaction

Step 3: Continue the payment flow according to action

When bizContent.status in the synchronous response is PROCESSING and action is returned, the front end needs to continue the payment flow according to action. The following explanation uses redirect-based local payment methods where action.type=PAYMENT_REDIRECT_URL.

`action.type`	Key field	Front-end handling
`PAYMENT_REDIRECT_URL`	`action.paymentRedirectUrl`	Redirect the shopper to this URL and let the shopper complete payment on the target payment page

Payment continuation notes

action.paymentRedirectUrl is the complete payment continuation link returned by PingPongCheckout. The merchant front end should use the original value returned by the server directly and should not append extra parameters or replace the domain or path.
We recommend opening the payment continuation link in a top-level page, system browser, or system-level web container. If you must use WKWebView or WebView, complete real-device verification in advance.

After the merchant server receives the continuation link from PingPong, pass the URL to the front end and let the merchant front end redirect the shopper to the payment method page.

The following examples show how the merchant front end loads the payment continuation link:

Web

function redirectOnWeb(action) {
  if (action?.type !== 'PAYMENT_REDIRECT_URL') return;
  const paymentWindow = window.open(action.paymentRedirectUrl, '_blank');
  if (!paymentWindow) {
    window.location.assign(action.paymentRedirectUrl);
  }
}

WAP

function redirectOnWap(action) {
  if (action?.type !== 'PAYMENT_REDIRECT_URL') return;
  window.location.href = action.paymentRedirectUrl;
}

App (iOS)

// Objective-C example:
NSURL *url = [NSURL URLWithString:paymentRedirectUrl];
if (url) {
    [[UIApplication sharedApplication] openURL:url
                                       options:@{}
                             completionHandler:^(BOOL success) {
        if (!success) {
            // Ask the shopper to retry or use another payment method
        }
    }];
}

// Swift example:
guard let url = URL(string: paymentRedirectUrl) else { return }
UIApplication.shared.open(url, options: [:]) { success in
    if !success {
        // Ask the shopper to retry or use another payment method
    }
}

App (Android)

// Java example:
try {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(paymentRedirectUrl));
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
} catch (Exception e) {
    e.printStackTrace();
}

// Kotlin example:
try {
    val intent = Intent(Intent.ACTION_VIEW, Uri.parse(paymentRedirectUrl))
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    startActivity(intent)
} catch (e: Exception) {
    e.printStackTrace()
}

Step 4: Get the final payment result

For local payments, we recommend confirming the final result through server-side asynchronous notification first. If the notification is delayed, not received, notification handling fails, or the merchant needs to verify the result immediately after the shopper returns, you can actively call transaction query. For the full transaction query integration solution, see After Payment > Transaction Query.

If you use the asynchronous notification flow, the merchant server should first return HTTP 2xx to acknowledge receipt, and then update the order according to the notification status.

Payment notification example:

{
  "accId": "2023042011040310224447",
  "clientId": "2023042011040310224",
  "code": "000000",
  "description": "Transaction succeeded",
  "sign": "{{Sign}}",
  "signType": "SHA256",
  "bizContent": {
    "amount": "1000.000000",
    "currency": "THB",
    "transactionId": "2026061050010001",
    "merchantTransactionId": "ORDER_202606100001",
    "requestId": "REQ_202606100001",
    "notifyType": "RECHARGE",
    "paymentMethod": {
      "type": "TrueMoney Wallet"
    },
    "status": "SUCCESS",
    "transactionTime": "1781080205000",
    "transactionEndingTime": "1781080265000",
    "captureDelayHours": 0
  }
}

Notification key fields:

Parameter	Description	Handling recommendation
`sign` / `signType`	Notification signature and signature type	Verify the signature before processing business logic
`bizContent.notifyType`	Notification type. Payment notification is always `RECHARGE`	Used to identify the event type
`bizContent.transactionId`	PingPong transaction ID	Save it for later query and reconciliation
`bizContent.merchantTransactionId`	Merchant order ID	Used to locate the merchant order
`bizContent.requestId`	Payment request ID	Used to locate the current payment request
`bizContent.amount` / `bizContent.currency`	Transaction amount and currency	Must be checked against the merchant order amount and currency
`bizContent.status`	Payment result status	Update the merchant order according to the status

Recommended handling for bizContent.status in the notification:

`bizContent.status`	Handling recommendation
`SUCCESS`	Payment succeeded. The merchant can fulfill the order or grant entitlements
`FAILED`	Payment failed. Keep the order unpaid or failed and allow the shopper to retry
`CANCEL`	Payment was cancelled or rejected by risk control. Do not treat the order as successful

Notification response example:

HTTP/1.1 200 OK
Content-Type: text/plain; charset=UTF-8
Content-Length: 2

OK

After Payment

Transaction Query

When the shopper returns from the payment page to the merchant result page, the asynchronous notification is delayed, notification handling fails, or the merchant needs to run a compensation task, you can call Transaction Query to get the latest transaction status.

Transaction query request example:

{
  "accId": "2023042011040310224447",
  "clientId": "2023042011040310224",
  "signType": "SHA256",
  "sign": "{{Sign}}",
  "version": "1.0",
  "bizContent": {
    "merchantTransactionId": "ORDER_202606100001",
    "requestId": "REQ_202606100001"
  }
}

Transaction query response example:

{
  "accId": "2023042011040310224447",
  "clientId": "2023042011040310224",
  "code": "000000",
  "description": "Transaction succeeded",
  "sign": "{{Sign}}",
  "signType": "SHA256",
  "bizContent": {
    "transactionId": "2026061050010001",
    "merchantTransactionId": "ORDER_202606100001",
    "requestId": "REQ_202606100001",
    "amount": "1000.000000",
    "currency": "THB",
    "status": "SUCCESS",
    "paymentMethod": {
      "type": "TrueMoney Wallet"
    },
    "transactionTime": "1781080205000",
    "transactionEndingTime": "1781080265000"
  }
}

Query response key fields:

Parameter	Handling recommendation
`code`	`000000` means the query request succeeded. A successful query request does not mean the payment succeeded
`bizContent.status`	The merchant order status should follow this field
`bizContent.transactionId`	Save the PingPong transaction ID for later refund, reconciliation, or query
`bizContent.amount` / `bizContent.currency`	Check against the merchant order amount and currency
`bizContent.transactionEndingTime`	Final transaction time, which can be used as the order completion time

Recommended handling for transaction query statuses:

`bizContent.status`	Handling recommendation
`SUCCESS`	Payment succeeded and the order can be completed
`FAILED`	Payment failed. The shopper may be allowed to retry
`PROCESSING`	Payment is still in progress. Continue waiting for the asynchronous notification or query again later
`CANCEL`	Payment was cancelled or rejected by risk control. Do not treat it as successful
`CLOSED`	The order has been closed and can no longer be paid

Refund

Refund capability varies by payment method, including whether refunds are supported, the refund window, whether partial refunds are supported, and whether multiple refunds are supported. Refer to Payment Methods or the target payment method page to confirm the exact refund capability.

After a payment succeeds, if the shopper requests a refund, the merchant cancels a paid order, or part or all of the funds need to be returned, you can call Refund Request for the original transaction.

PingPongCheckout supports the following refund capabilities:

Full refund
Partial refund
Multiple refunds, as long as the cumulative refund amount does not exceed the refundable amount of the original transaction

Refer to Refund for the refund integration solution. For request parameters, response fields, and handling rules, see Refund Request. To confirm the refund result, see Refund Query.

Reconciliation
