Init Config

PayermaxClient client=DefaultPayermaxClient.getInstance();
        client.setEnv(Env.UAT);
// or set the other base url
// client.setBaseUrl("https://the-other-url.payermax.com/aggregate-pay/api/gateway");

If you have only one merchant

        String merchantPrivateKey="get your private key from testGenKeyPair()";
        String payermaxPublicKey="get payermax public key from dashboard";
        String merchantNo="get merchantNo from dashboard";
        String appId="get appId from dashboard";

        //In ISV mode, spMerchantNo and merchantAuthToken is required
        String spMerchantNo = "get spMerchantNo from dashboard";
        String merchantAuthToken = "get merchantAuthToken from dashboard";
        
        MerchantConfig merchantConfig=MerchantConfig.Builder.builder()
        .merchantPrivateKey(merchantPrivateKey)
        .payermaxPublicKey(payermaxPublicKey)
        .merchantNo(merchantNo)
        .appId(appId)
        //In ISV mode, spMerchantNo and merchantAuthToken is required
        .spMerchantNo(spMerchantNo)
        .merchantAuthToken(merchantAuthToken)
        .build();
        GlobalMerchantConfig.setDefaultConfig(merchantConfig);

If you have multi merchants

Map<String, String> keyPair=RsaUtils.createKeyPair();
        String merchantPrivateKey=keyPair.get(RsaUtils.PRIVATE_KEY_FILE);
        String payermaxPublicKey="get payermax public key from dashboard";
        String merchantNo="the other merchant no";
        String appId="get appId from dashboard";

        //In ISV mode, spMerchantNo and merchantAuthToken is required
        String spMerchantNo = "get spMerchantNo from dashboard";
        String merchantAuthToken = "get merchantAuthToken from dashboard";
        
        MerchantConfig merchantConfig=MerchantConfig.Builder.builder()
        .merchantPrivateKey(merchantPrivateKey)
        .payermaxPublicKey(payermaxPublicKey)
        .merchantNo(merchantNo)
        .appId(appId)
        //In ISV mode, spMerchantNo and merchantAuthToken is required
        .spMerchantNo(spMerchantNo)
        .merchantAuthToken(merchantAuthToken)
        .build();
        GlobalMerchantConfig.addConfig(merchantConfig);
// MerchantConfig merchantConfig2 = ....
// GlobalMerchantConfig.addConfig(merchantConfig2);
// MerchantConfig merchantConfig3 = ....
// GlobalMerchantConfig.addConfig(merchantConfig3);

Send request

Use json api

String json="{\"outTradeNo\":\"out1254125412\",\"subject\":\"this is subject\",\"totalAmount\":\"10000\",\"currency\":\"IDR\",\"country\":\"ID\",\"userId\":\"userId\",\"language\":\"\",\"reference\":\"\",\"frontCallbackURL\":\"https://www.qq2ddsdfsadfsdfsd.com\",\"notifyUrl\":\"https://www.noticddddasdfasdfe.com\",\"goodsDetails\":[{\"goodsId\":\"D002\",\"goodsName\":\"韩版修身牛仔裤男\",\"quantity\":\"2\",\"price\":\"500\",\"goodsCurrency\":\"IDR\",\"showUrl\":\"https://xxxx.light.png\"}],\"shippingInfo\":{\"firstName\":\"zhang\",\"middleName\":\"shang\",\"lastName\":\"feng\",\"phoneNo\":\"13009090980\",\"email\":\"bacde@ushareit.com\",\"address1\":\"二仙桥\",\"address2\":\"成华大道\",\"city\":\"成都市\",\"region\":\"武侯区\",\"state\":\"州\",\"country\":\"ID\",\"zipCode\":\"000000\"},\"billingInfo\":{\"firstName\":\"账单各\",\"middleName\":\"账单中间名\",\"lastName\":\"账单姓\",\"email\":\"abse@ushareit.com\",\"phone\":\"182927192799\",\"address1\":\"账单地址1\",\"address2\":\"账单地址2\",\"city\":\"账单地址所在城市\",\"region\":\"账单地址所在区域\",\"state\":\"账单地址所在州\",\"country\":\"地址\",\"zipCode\":\"710603\"}}";
        JSONObject jsonObject=JSON.parseObject(json);

// client构造完成后，可以进行反复使用，不需要重复获取实例
// send with default merchant config        
        String result=client.send("orderAndPay",jsonObject);

Use easy request api

TradeOrderRequest request=new TradeOrderRequest();
        request.setOutTradeNo("out41254125412");
        request.setSubject("this is subject");
        request.setTotalAmount(new BigDecimal(10000));
        request.setCurrency("IDR");
        request.setCountry("ID");
        request.setUserId("test userId");
// set the other information
// request.setLanguage();
// ......
// send with default merchant config        
        GatewayResult<TradePayOrderResponse> resp=request.send();

Use specify merchant config

client.send("merchant no");

Verify Notification

String body="";// from http post body
        String sign="";// from http header, header name is 'sign'        
        boolean result=client.verifyNotification(body,sign);
