Initiate Payment

To initiate a UPI transaction, use the startPayment method:

Java

sdk.startPayment("AMOUNT", // Amount to be paid
        "ORDER_ID", // Unique Order ID
        "CUSTOMER_NAME", // Customer's name
        "CUSTOMER_EMAIL", // Customer's email
        "CUSTOMER_NUMBER", // Customer's contact number
        new PaymentCallback() {
            @Override
            public void onPaymentSuccess(String order_id, String message) {
                Toast.makeText(MainActivity.this, message, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPaymentFailed(String order_id, String message) {
                String logMessage = message + " Order Id " + order_id;
                Toast.makeText(MainActivity.this, logMessage, Toast.LENGTH_SHORT).show();
                Log.d("PaymentFailed", logMessage);
            }
        });

Parameters

• AMOUNT: The payment amount.
• ORDER_ID: A unique order identifier generated by your app.
• CUSTOMER_NAME: The name of the customer making the payment.
• CUSTOMER_EMAIL: The customer's email address.
• CUSTOMER_NUMBER: The customer's contact number.
• PaymentCallback: Handles success and failure responses.

Payment Callback

Implement the PaymentCallback interface to handle payment responses:

• onPaymentSuccess(String order_id, String message): Called when the payment is successful.
• onPaymentFailed(String order_id, String message): Called when the payment fails.

Logging and Debugging

For debugging failed transactions, use:

Java

Log.d("PaymentFailed", logMessage);

This helps in tracking payment issues by logging the failure message and order ID.
