Когда я пытаюсь интегрировать интеграцию PayU. Какие бы изменения я ни вносил, я получаю неверный хэш. Я думаю, что совершаю какую-то незначительную ошибку.

Для генерации хэша, который я написал на PHP, хотя в настоящее время все данные статичны, я сопоставил все только одинаковые.

В следующем примере php я использую payment_related_details_for_mobile_sdk_hash ключ в Android

Вот мой код:

 paymentIntegration("741852963", "1.0", "SmartAuto", "Piyush", "piyush.sahay@mail.com", "330122983a2492fe6ff18ad2fcccc6a78ed499f988a6b06b226ff4f27b9b390356f18c297282105b2dbb70166bfd0c2332dfa4e55a784543658bd67330f98b39", "XXXXX:XXXXX@XXXXX.com");

private void paymentIntegration(String txnId, String amount, String productName, String userName, String userEmail, String hash1, String userCredentials) {
        HashMap<String, Object> additionalParams = new HashMap<>();
        additionalParams.put(PayUCheckoutProConstants.CP_UDF1, "udf1");
        additionalParams.put(PayUCheckoutProConstants.CP_UDF2, "udf2");
        additionalParams.put(PayUCheckoutProConstants.CP_UDF3, "udf3");
        additionalParams.put(PayUCheckoutProConstants.CP_UDF4, "udf4");
        additionalParams.put(PayUCheckoutProConstants.CP_UDF5, "udf5");



        PayUPaymentParams.Builder builder = new PayUPaymentParams.Builder();
        builder.setAmount(amount)
            .setIsProduction(true)
            .setProductInfo(productName)
            .setKey(MERCHANT_KEY)
            .setPhone("XXXXXXXX")
            .setTransactionId(txnId)
            .setFirstName(userName)
            .setEmail(userEmail)
            .setSurl("https://payu.herokuapp.com/success")
            .setFurl("https://payu.herokuapp.com/failure")
            .setUserCredential(userCredentials)
            .setAdditionalParams(additionalParams);

        PayUPaymentParams payUPaymentParams = builder.build();

        PayUCheckoutPro.open(
                this,
                payUPaymentParams,
                new PayUCheckoutProListener() {

                        HashMap<String,Object> result = (HashMap<String, Object>) response;
                        String payuResponse = (String)result.get(PayUCheckoutProConstants.CP_PAYU_RESPONSE);
                        String merchantResponse = (String) result.get(PayUCheckoutProConstants.CP_MERCHANT_RESPONSE);
                    }

                        String hashData = valueMap.get(PayUCheckoutProConstants.CP_HASH_STRING);
                        if (!TextUtils.isEmpty(hashName) amp;amp; !TextUtils.isEmpty(hashData)) {
                            //Do not generate hash from local, it needs to be calculated from server side only. Here, hashString contains hash created from your server side.
                            String hash = hash1;
                            HashMap<String, String> dataMap = new HashMap<>();
                            dataMap.put(hashName, hash);
                            hashGenerationListener.onHashGenerated(dataMap);
                        }
                    }

Вот мой PHP-код для генерации хэша:
