# Accept payments with Apple Pay
> Learn how to accept payments with Apple Pay through Omnichannel.
Through the Apple Pay service, buyers can make payments using credit or debit cards stored in their Apple accounts. With Antom Checkout Page (CKP), you do not need to integrate the Apple Pay SDK separately. Checkout Page will automatically load Apple Pay services for you and can be configured to support Apple Pay as an express payment method.

#### Tab: Mobile
## Integration preparations
Before you start integrating, read the [Integration Guide](https://docs.antom.com/integration_guide_en.md) and [API Overview](https://docs.antom.com/ac/ams/api_fund.md) documents to understand the integration steps of the server-side API and the precautions for calling the API. Furthermore, ensure that the following prerequisites are met:
- Obtain a client ID
- Complete the key configuration
- Complete the configuration of _paymentNotifyUrl_ to receive the asynchronous notification
- Integrate the server-side SDK package, install the server-side library, and initialize a request instance. For more details, refer to [Server-side SDKs](https://docs.antom.com/ac/sdks/server_sdks.md).
## Integration steps
Follow these steps to start the integration:
1. Create a payment session
2. Redirect to Antom Checkout Page
3. Obtain the payment result
4. Capture
### Step 1: Create a payment session Server-side
When the buyer clicks payment on the product details or shopping cart page, they can select the payment method provided by Antom. For payment method configurations, see [Specify a payment method](#f4mYc). When the buyer makes a payment, you need to collect key information, such as the payment request ID, order details, payment redirect URL, and payment notification URL. You need to call the [**createPaymentSession (One-time Payments)**](https://docs.antom.com/ac/ams/session_cashier.md) API and pass in the following parameters to create a payment session, then redirect to the Antom Checkout Page.
| **Type** | **Parameter name** | **Required** | **Description** |
| --- | --- | --- | --- |
| Basic parameters | _productCode_ | Yes | The value of this field in this scenario is fixed as `CASHIER_PAYMENT`. |
| Basic parameters | _productScene_ | Yes | The value of this field in this scenario is fixed as `CHECKOUT_PAYMENT`. |
| Basic parameters | _paymentRequestId_ | Yes | The unique ID assigned by a merchant to identify a payment request. |
| Basic parameters | _paymentAmount_ | Yes | The payment amount that you requests to receive in the order currency. |
| Basic parameters | _paymentRedirectUrl_ | Yes | The merchant page URL that the buyer is redirected to after the payment is completed. |
| Basic parameters | _paymentNotifyUrl_ | No | The URL that is used to receive the payment result notification. You can also set the URL to receive the result notification on [Antom Dashboard](https://dashboard.alipay.com/global-payments/account/login?goto=https%3A%2F%2Fdashboard.alipay.com%2Fglobal-payments%2Fhome). |
| Basic parameters | _settlementStrategy_ | No | The settlement strategy for the payment request. Specify the _settlementCurrency_ parameter in the API if you signed up for multiple settlement currencies. |
| Basic parameters | _locale_ | No | Language tag specified for the Checkout Page. If this field is empty or set to automatic, the default language setting of the browser will be used, which is usually English. |
| Basic parameters | _paymentFactor.captureMode_ | No | Indicates the method for capturing funds after the user authorizes the payment. Valid values are: - `AUTOMATIC`: indicates that Antom automatically captures the funds after the authorization. The same applies when the value is empty or you do not pass in this parameter. - `MANUAL`: indicates that you manually capture the funds by calling the [**capture (One-time Payments)**](https://docs.antom.com/ac/ams/capture.md) API. |
| Order parameters | _order.goods_ | No | Goods information in the order. If you use this parameter to pass goods information in the API, you must specify the following parameters: - _referenceGoodsId_: The unique ID to identify the goods. - _goodsName_: Goods name. - _goodsUnitAmount_: Price of goods. - _goodsQuantity_: Quantity of goods. |
| Order parameters | _order.orderAmount_ | Yes | The order amount on the merchant side for the services or products provided to the buyer. This parameter is used to display the buyer’s consumption record or payment result page. It includes the following parameters: - _currency_: The transaction currency that is specified in the contract. A 3-letter currency code that follows the [ISO 4217](https://www.iso.org/iso-4217-currency-codes.html) standard. - _value_: The amount to charge as a positive integer in the smallest currency unit. > **Note**: If goods information is specified, the value of _order.orderAmount.value_ must exactly match the total amount calculated from the goods details. Otherwise, the API will return a parameter validation error. Calculation logic: Σ(_goods\[i\].goodsUnitAmount.value_ × _goods\[i\].goodsQuantity_) = _order.orderAmount.value_ |
| Order parameters | _order.referenceOrderId_ | Yes | The unique ID to identify the order on the merchant side. |
| Order parameters | _order.orderDescription_ | Yes | Summary description of the order on the merchant side. |
| Order parameters | _order.buyer_ | Yes | The buyer information of the merchant side. At least one of the following information must be provided: - _order.buyer.referenceBuyerId_ - _order.buyer.buyerPhoneNo_ - _order.buyer.buyerEmail_ > **Note**: If buyer information is not passed, selecting Apple Pay and submitting the payment will trigger a page error and cause the payment process to fail. |
| Apple Pay parameters | _availablePaymentMethod.paymentMethodMetaData.applePayConfiguration_ | No | In the Checkout Page scenario, it is recommended to use the default value for this parameter. > **Note**: You can specify Apple Pay as the only payment method in the checkout page by setting this parameter. For more details, refer to [Specify a payment method](#f4mYc). |
| Apple Pay parameters | _availablePaymentMethod.paymentMethodTypeList.__expressCheckout_ | No | You can specify Apple Pay as an express payment method either by setting this parameter to `true` or via the [Antom Dashboard](https://dashboard.alipay.com/global-payments/home). |
The above parameters are the basic parameters for creating a payment session. For complete and additional requirements for specific payment methods, please refer to [**createPaymentSession (One-time Payments)**](https://docs.antom.com/ac/ams/session_cashier.md).
The following sample code shows how to call the [**createPaymentSession (One-time Payments)**](https://docs.antom.com/ac/ams/session_cashier.md) API:
```java
public static void createPaymentSession() {
AlipayPaymentSessionRequest alipayPaymentSessionRequest = new AlipayPaymentSessionRequest();
alipayPaymentSessionRequest.setProductCode(ProductCodeType.CASHIER_PAYMENT);
alipayPaymentSessionRequest.setProductScene(ProductSceneConstants.CHECKOUT_PAYMENT);
// replace with your paymentRequestId
String paymentRequestId = UUID.randomUUID().toString();
alipayPaymentSessionRequest.setPaymentRequestId(paymentRequestId);
// replace with your orderId
String orderId = UUID.randomUUID().toString();
// set buyer info
Buyer buyer = Buyer.builder().referenceBuyerId("yourBuyerId").build();
// convert amount unit(in practice, amount should be calculated on your serverside)
// For details, please refer to: Usage rules of the Amount object
Amount goodAmount = Amount.builder().currency("SGD").value("3000").build();
// set goods info
// note that goods.referenceGoodsId, good.referenceGoodsId, and goods.goodsName are required
Goods goods = Goods.builder().goodsBrand("Antom Brand").goodsCategory("outdoor goods/bag").goodsName("Classic Woman Bag").goodsQuantity("2")
.goodsSkuName("Black").goodsImageUrl("https://mdn.alipayobjects.com/portal_pdqp4x/afts/file/A*H8M9RrxlArAAAAAAAAAAAAAAAQAAAQ")
.goodsUnitAmount(goodAmount).goodsUrl("https://yourGoodsUrl").referenceGoodsId("yourGoodsId").build();
// set amount
// amount.value equals goodsAmount.value * goods.goodsQuantity
// for the currencies supported by payment methods, please refer to: Supported payment methods
Amount amount = Amount.builder().currency("SGD").value("6000").build();
alipayPaymentSessionRequest.setPaymentAmount(amount);
// set order info
// note that order.orderAmount, order.referenceOrderId, and order.orderDescription are required
Order order = Order.builder().referenceOrderId(orderId)
.orderDescription("antom ckp testing order").orderAmount(amount).buyer(buyer).goods(Stream.of(goods).collect(Collectors.toList())).build();
alipayPaymentSessionRequest.setOrder(order);
// replace with your notify url
// or configure your notify url here: Notification URL
alipayPaymentSessionRequest.setPaymentNotifyUrl("http://www.yourNotifyUrl.com/payment/receiveNotify");
// replace with your redirect url
alipayPaymentSessionRequest.setPaymentRedirectUrl(
"http://localhost:8080/index.html?paymentRequestId=" + paymentRequestId);
AlipayPaymentSessionResponse alipayPaymentSessionResponse;
try {
System.out.println(JSON.toJSONString(alipayPaymentSessionRequest));
alipayPaymentSessionResponse = CLIENT.execute(alipayPaymentSessionRequest);
} catch (AlipayApiException e) {
String errorMsg = e.getMessage();
// handle error condition
}
}
```
The following shows the sample code of a request:

"productCode": "CASHIER_PAYMENT",
"productScene": "CHECKOUT_PAYMENT"
}
```
The following shows the sample code of a response, which contains the following parameters:
- _pa__ymentSessionData_: The encrypted payment session data. Pass the data to your front end.
- _paymentSessionExpiryTime_: The specific date and time after which the payment session will expire.
- _normalUrl_: The URL used to redirect to the Checkout Page.
```json
{
"normalUrl": "https://checkout.antom.com/checkout-page/pages/payment/index.html?sessionData=1iwX2rH5kXnUGT5372d0kHD7PwcgPmRSMgAsvKs8hqRkqobbtWbep59PU2eO5w72h%2B%2XXXX",

"result": {
"resultCode": "SUCCESS",
"resultMessage": "success.",
"resultStatus": "S"
}
}
```
The table shows the possible values that the _result.resultStatus_ field in the request message may return. Please handle the result according to the guidances:
| **_result.resultStatus_** | **Message** | **Further actions** |
| --- | --- | --- |
| `S` | Indicates that payment session creation succeeded. | Obtain the Antom Checkout Page URL (_normalUrl_) and return to the merchant's front end. For detailed steps, please refer to [Step 2](#rJXV8). |
| `U` | Indicates that payment session creation failed for unknown reasons. | Please change the _paymentRequestId_ and call the API again to resolve the issue. Please contact Antom Technical Support if the problem persists. |
| `F` | Indicates that the payment session creation failed. | Please check and verify whether the current API required request fields (including header fields and body fields) are correctly passed and valid. |
> **Note**: If you did not receive a response message, it might be due to a network timeout. Please change the _paymentRequestId_ and call the API again to resolve the issue.
### Step 2: Redirect to Antom Checkout Page Client-side
After the merchant server obtains _normalUrl_ and passes it to front end, it will redirect from the merchant front end to the Antom Checkout Page.
#### Tab: Web
After obtaining the _normalUrl,_ you need to redirect the page to Antom Checkout Page in the browser, or open it in a new tab.
```javascript
if (serverResponse.normalUrl != null) {
window.open(serverResponse.normalUrl, '_blank');
}
```
#### Tab: WAP
After obtaining the _normalUrl,_ you need to redirect the page to Antom Checkout Page in the browser, or open it in a new tab.
```javascript
window.location.href = URL;
```
The image below shows the rendering result of the redirected Antom Checkout Page:
### Step 3: Obtain the authorization result Server-side
Upon authorized payment success, failure, or order timeout, Antom will send the corresponding authorization results to you through server interaction. You can obtain the authorization result using one of the following methods:
- Receive asynchronous notifications from Antom
- Inquire about the result
#### Receive asynchronous notifications
Follow the steps below to receive and process asynchronous notifications from Antom:
1. **Configure the webhook URL to receive asynchronous notifications**
When an authorized payment succeeds or fails, Antom will send an asynchronous notification to the webhook URL you set. You can choose one of the following two methods to configure the webhook URL for receiving notifications (if both are set, the URL specified in the request takes precedence):
- If each of your orders has a unique notification URL, it is recommended to set the webhook URL in each request. You can pass the asynchronous notification receiving URL for the specific order through _paymentNotifyUrl_ in the [**createPaymentSession (One-time Payments)**](https://docs.antom.com/ac/ams/session_cashier.md) API.
- If all your orders share a unified notification URL, you can set the webhook URL on [Antom Dashboard](https://dashboard.alipay.com/global-payments/developers/iNotify) through **Developer > Notification URL**. For detailed steps, refer to [Notification URL](https://docs.antom.com/ac/merchant_service/notification.md).
The following code shows a sample of the asynchronous notification request:
```json
{
"actualPaymentAmount": {
"currency": "HKD",
"value": "7200"
},
"authExpiryTime": "2026-05-15T23:32:53-07:00",

"result": {
"resultCode": "SUCCESS",
"resultMessage": "success.",
"resultStatus": "S"
}
}
```
The following table shows the possible values of _result.resultStatus_ in the notification request of authorization result. Please handle the result according to the guidance provided:
| _**result.resultStatus**_ | **Message** | **Further action** |
| --- | --- | --- |
| `S` | Authorization was successful. | The order can be proceeded with capture. |
| `F` | Authorization failed. | Please submit a new order with a different _paymentRequestId_. |
2. **Verify the asynchronous notification**
When you receive an asynchronous notification from Antom, you are required to return the response in the [Sample code](https://docs.antom.com/ac/cashierpay/notifications.md#vQK5A) format, but you do not need to countersign the response.
You need to verify the signature of the notification sent by Antom:
```java
/**
* receive notify
*
* @param request request
* @param notifyBody notify body
* @return Result
*/
@PostMapping("/receiveNotify")
@ResponseBody
public Result receiveNotify(HttpServletRequest request, @RequestBody String notifyBody) {
// retrieve the required parameters from http request
String requestUri = request.getRequestURI();
String requestMethod = request.getMethod();
// retrieve the required parameters from request header
String requestTime = request.getHeader("request-time");
String clientId = request.getHeader("client-id");
String signature = request.getHeader("signature");
try {
// verify the signature of notification
boolean verifyResult = WebhookTool.checkSignature(requestUri, requestMethod, clientId,
requestTime, signature, notifyBody, ANTOM_PUBLIC_KEY);
if (!verifyResult) {
throw new RuntimeException("Invalid notify signature");
}
// deserialize the notification body
JSONObject jsonObject = JSON.parseObject(notifyBody);
String notifyType = (String)jsonObject.get("notifyType");
if("PAYMENT_RESULT".equals(notifyType)){
AlipayPayResultNotify paymentNotify = jsonObject.toJavaObject(AlipayPayResultNotify.class);
if (paymentNotify != null && "SUCCESS".equals(paymentNotify.getResult().getResultCode())) {
// handle your own business logic.
// e.g. The relationship between payment information and users is kept in the database.
System.out.println("receive payment notify: " + JSON.toJSONString(paymentNotify));
return Result.builder().resultCode("SUCCESS").resultMessage("success.").resultStatus(ResultStatusType.S).build();
}
}else if("CAPTURE_RESULT".equals(notifyType)){
AlipayCaptureResultNotify captureNotify = jsonObject.toJavaObject(AlipayCaptureResultNotify.class);
if (captureNotify != null && "SUCCESS".equals(captureNotify.getResult().getResultCode())) {
// handle your own business logic.
System.out.println("receive capture notify: " + JSON.toJSONString(captureNotify));
return Result.builder().resultCode("SUCCESS").resultMessage("success.").resultStatus(ResultStatusType.S).build();
}
}
} catch (Exception e) {
// handle error condition
return Result.builder().resultCode("FAIL").resultMessage("fail.").resultStatus(ResultStatusType.F).build();
}
return Result.builder().resultCode("SYSTEM_ERROR").resultMessage("system error.").resultStatus(ResultStatusType.F).build();
}
```
Whether the payment is successful or not, each notification request must be responded to in the format specified below. Otherwise, Antom will resend the asynchronous notification.
```json
{
"result": {
"resultCode": "SUCCESS",
"resultStatus": "S",
"resultMessage": "success"
}
}
```
> **Common questions**
>
> **Q: When will the notification be sent?**
>
> A: The sending time of asynchronous notifications varies in different scenarios.
>
> - If the payment is successfully completed, Antom will usually send you an asynchronous notification within 3 to 5 seconds. For some payment methods like cash payment, the notification might take a bit longer.
> - If the buyer does not submit a payment, when the payment session times out, Antom does not send an asynchronous notification.
> - If the buyer submits a payment but the final payment is not completed:
>
> - When the last order is closed, if the payment session is still valid, Antom will send asynchronous notifications when the payment session expires.
> - When the last order is closed, if the payment session expired, Antom will send an asynchronous notification when the last order is closed.
>
> **Note**: The default payment session expiry time is 1 hour. The time it takes to close an order varies for different payment methods, the default is 14 minutes.
>
> **Q: Will the asynchronous notification be re-sent?**
>
> A: Yes, the asynchronous notification will be re-sent automatically within 24 hours for the following cases:
>
> - If you didn't receive the asynchronous notification due to network reasons.
> - If you receive an asynchronous notification from Antom, but you didn't make a response to the notification in the [Sample code](https://docs.antom.com/ac/cashierpay/notifications.md#vQK5A) format.
>
> The notification can be resent up to 8 times or until a correct response is received to terminate delivery. The sending intervals are as follows: 0 minutes, 2 minutes, 10 minutes, 10 minutes, 1 hour, 2 hours, 6 hours, and 15 hours.
>
> **Q:** **What are the key parameters in the notification that I need to use?**
>
> A: Pay attention to the following key parameters:
>
> - _result_: indicates the payment result of the order.
> - _paymentRequestId_: indicates the payment request number you generated for consult, cancel, and reconciliation.
> - _paymentId_: indicates the payment order number generated by Antom, used for refund and reconciliation.
> - _paymentAmount_: indicates the payment amount.
> - _paymentMethodTpye_: indicates the payment method type that is included in payment method options.
>
> **Q: There are two types of asynchronous notifications. Which one should be used as the basis for shipment?**
>
> A: When you receives a `PAYMENT_RESULT` _notifyType_ notification, you should first check whether the _paymentMethodType_ is `CARD`. If it is not `CARD`, you can decide whether to proceed with shipment based on the result of this notification. If it is `CARD`, you need to wait for a notification of `CAPTURE_RESULT` type before making the decision to ship.
#### Inquire about the result
You can also inquire about the authorization result by calling the [**inquiryPayment**](https://docs.antom.com/ac/ams/paymentri_online.md) API using _paymentRequestId_ from the payment request.
The following sample code shows how to call the [**inquiryPayment**](https://docs.antom.com/ac/ams/paymentri_online.md) API:
```java
public static void inquiryPayment() {
AlipayPayQueryRequest alipayPayQueryRequest = new AlipayPayQueryRequest();
// replace with your paymentRequestId
alipayPayQueryRequest.setPaymentRequestId("yourPaymentRequestId");
AlipayPayQueryResponse alipayPayQueryResponse = null;
try {
alipayPayQueryResponse = CLIENT.execute(alipayPayQueryRequest);
} catch (AlipayApiException e) {
String errorMsg = e.getMessage();
// handle error condition
}
}
```
The following sample code shows a response message:
```json

"transactionType": "CAPTURE"
}
],
"result": {
"resultCode": "SUCCESS",
"resultMessage": "success.",
"resultStatus": "S"
}
}
```
Please handle the result based on the value of the _paymentStatus_ parameter in the response. For specific return values, refer to the [API documentation](https://docs.antom.com/ac/ams/paymentri_online.md#Responseparameters-paymentStatus).
> **Note**: When inquiring about the transaction, if the buyer does not submit the order, the `ORDER_NOT_EXIST` error code will be returned. This error is not returned if the order is submitted.
### Step 4: Capture Server-side
If payment is successful, Antom will automatically initiate capture for you, while you can also initiate capture manually. After capture, you can obtain the capture result either via asynchronous notification or active query. You should decide whether to ship goods based on the capture result. For specific operations, refer to [Capture](https://docs.antom.com/ac/cashierpay/capture.md).
## **After payments**
After completing the payment, you can perform the following actions:
### Refund Server-side
To learn about Antom refund rules and how to initiate a refund for a successful transaction, see [Refund](https://docs.antom.com/ac/cashierpay/refund.md) for more information.
### Dispute Server-side
When a buyer chooses to pay with a card, a dispute may occur. To learn more, see [Dispute resolution](https://docs.antom.com/ac/dispute/dispute_resolution.md).
### Reconciliation Server-side
After the transaction is completed, use the financial reports provided by Antom for reconciliation. For more information on how to reconcile and the settlement rules of Antom, please refer to [Reconciliation](https://docs.antom.com/ac/cashierpay/reconcile.md).
## Additional content
### Specify a payment method
You can specify payment methods on [Antom Dashboard](https://dashboard.alipay.com/global-payments/account/login?goto=https%3A%2F%2Fdashboard.alipay.com%2Fglobal-payments%2Fhome) through **Payments > Checkout page** **\> Payment methods**. You can also pass the parameters in the [**createPaymentSession (One-time Payments)**](https://docs.antom.com/ac/ams/session_cashier.md) API to specify the display of payment methods on Checkout Page, the order of the payment method list, and the display of express payments. For specific steps, refer to [Specify a payment method](https://docs.antom.com/ac/pm/specify_pm.md).
> **Note**: If you pass parameters through the API, the API values take priority.
