I get an error for initiating a remote transaction using paynow for ecocash mobile payment
private void processImmediatePayment(LoaneeRequest request, String categoryName) throws IOException, URISyntaxException, InterruptedException {
zw.co.paynow.core.Payment payment = paynow.createPayment("", “”);
payment.add(categoryName, request.getPrice());
String formattedContact = request.getContactDetails().replaceFirst("^263", "0");
MobileInitResponse response = paynow.sendMobile(payment, formattedContact, MobileMoneyMethod.ECOCASH);
if (response.isRequestSuccess()) {
String pollUrl = response.pollUrl();
StatusResponse status = null;
int retries = 5;
int delay = 5000;
for (int i = 0; i < retries; i++) {
status = paynow.pollTransaction(pollUrl);
System.out.println("Polling attempt " + (i + 1) + ": " + status);
if (status.paid()) {
break;
}
Thread.sleep(delay);
}
if (status == null || !status.paid()) {
System.out.println("Why you no pay?");
throw new ExceptionMessage("Payment Transaction Failed");
}
} else {
System.out.println(response.errors());
throw new ExceptionMessage("Payment processing failed. Please try again.");
}
that’s the method in Java
locally its working but after deploying to a live environment I get an error
