-
Create and initialize a
OPayPaymentClientinstance. -
Create an API request and set parameters.
-
Initiate the request and handle the response or exceptions.

//initialize config
DefaultProfile profile = DefaultProfile.getProfile(Environment.SANDBOX, "<your-merchant-id>", "<your-public-key>", "<your-private-key>");
//Create and initialize a OPayPaymentClient instance
OPayPaymentClient client = new OPayPaymentClient(profile);
//Create an API request and set parameters
CashierInitializeRequest request = new CashierInitializeRequest();
request.setReference(System.currentTimeMillis() + "");
request.setMchShortName("Test");
request.setProductDesc("The best wireless earphone in history");
request.setProductName("IPhone");
request.setUserPhone("+2348161564736");
request.setUserRequestIp("123.4.5.6");
request.setAmount("100");
request.setCurrency("NGN");
List<CashierPayTypeEnum> payTypes = new ArrayList();
payTypes.add(CashierPayTypeEnum.BalancePayment);
payTypes.add(CashierPayTypeEnum.OWealth);
payTypes.add(CashierPayTypeEnum.BonusPayment);
request.setPayTypes(payTypes);
List<CashierPayMethodEnum> payMethods = new ArrayList();
payMethods.add(CashierPayMethodEnum.account);
payMethods.add(CashierPayMethodEnum.qrcode);
payMethods.add(CashierPayMethodEnum.bankCard);
request.setPayMethods(payMethods);
request.setCallbackUrl("http://www.baidu.com");
request.setReturnUrl("http://www.baidu.com");
request.setExpireAt("10");
System.out.println(request);
// Initiate the request and handle the response or exceptions
CashierInitializeResponse response = null;
try {
response = client.cashierInitialize(request);
} catch (OPayException e) {
e.printStackTrace();
}
}
