Instore Card Refund

Overview

A Refund transaction is a fundamental process for reversing payments in various physical settings. It facilitates the real-time, immediate return of funds to a customer's credit or debit card, making it ideal for handling returns, overcharges, or customer dissatisfaction. This type of transaction is a staple in environments such as department stores, convenience stores, restaurants, and other locations where prompt reversal of payment is crucial. Refunds ensure that customers are credited back promptly, maintaining customer satisfaction and trust. This process is essential for businesses to manage returns efficiently and uphold their service standards.

Create an Instore Card Purchase Transaction Request

// Import necessary classes
import com.pxpfinancial.sdk.pos.TransactionRequest
import com.pxpfinancial.sdk.pos.PointOfInteraction
import com.pxpfinancial.sdk.pos.Amounts
import com.pxpfinancial.sdk.pos.TransactionMethod
import java.text.SimpleDateFormat
import java.util.Date

// Define the AnyPayCredentials data class
data class AnyPayCredentials(
    val username: String,
    val password: String
)

// Define merchant and transaction details
val merchant = "MERCHANT-1"
val site = "SITE-1"
val merchantTransactionId = "This_is_my_merchant_transaction_id"
val merchantTransactionDate = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX").format(Date())

// Create an instance of AnyPayCredentials
val anyPayCredentials = AnyPayCredentials(
    username = "PxpUser",
    password = "PxpPassword"
)

// Point of Interaction details with AnyPayCredentials object
val pointOfInteraction = PointOfInteraction(
    pointOfSaleId = "001",
    culture = "en",
    anyPayCredentials = anyPayCredentials // Include the credentials object here if processing through the AnyPay Gateway
)

// Transaction amount details
val amounts = Amounts(
    currencyCode = "GBP",
    transaction = 20.00
)

// Create an instance of TransactionMethod
val transactionMethod = TransactionMethod(
    entryType = "Instore",
    fundingType = "Card",
    intent = "Refund"
)

// Function to build transaction request
fun buildTransactionRequest(): TransactionRequest {
    return TransactionRequest(
        merchant = merchant,
        site = site,
        pointOfInteraction = pointOfInteraction,
        merchantTransactionId = merchantTransactionId,
        merchantTransactionDate = merchantTransactionDate,
        amounts = amounts,
        transactionMethod = transactionMethod // Add the transactionMethod object here
    )
}

Handle an Instore Card Purchase Transaction Response

After processing an instore card purchase, you'll receive a response containing several key fields.

// Import necessary classes
import com.pxpfinancial.sdk.pos.TransactionResponse
import kotlinx.coroutines.*
import java.text.SimpleDateFormat
import java.util.Date

// Function to handle transaction response
private fun handleTransactionResponse(response: TransactionResponse?) {
    response ?: run {
        println("Transaction timed out or no response received.")
        return
    }

    // Accessing fields in the base response
    val state = response.state
    val approvalCode = response.approvalCode
    val merchantOrderId = response.merchantOrderId
    val merchantTransactionId = response.merchantTransactionId
    val systemTransactionId = response.systemTransactionId
    val providerTransactionId = response.providerTransactionId
    
    // Accessing fields in card response
    val cardScheme = response.card.cardScheme
  	val cardScheme = response.card.gatewayTokenId  
  	
    // Accessing fields in provider response
    val provider = response.provider.provider
    val providerCode = response.provider.code
    val providerMessage = response.provider.message
  	
  	// Accessing fields for receipt data
    val merchantId = response.receiptData.merchantId
    val terminalId = response.receiptData.terminalId  
  	val entryTye = response.receiptData.entryType
    val maskedPrimaryAccountNumber = response.receiptData.maskedPrimaryAccountNumber
  	val expiryDateMonth = response.receiptData.expiryDateMonth
  	val expiryDateYear = response.receiptData.expiryDateYear
  	val holderName = response.receiptData.holderName    
  	val applicationId = response.receiptData.applicationId
  	val applicationLabel = response.receiptData.applicationLabel  
  	val preferredName = response.receiptData.preferredName	
  	val cardVerificaitonResults = response.receiptData.terminalVerificationResults	
  
    // Additional business logic based on the transaction state
    when (state) {
        "Authorised" -> {
            // Handle authorised transaction
            println("Transaction authorised successfully.")
            // Perform further actions like updating UI, saving transaction details, etc.
        }
        "Declined" -> {
            // Handle declined transaction
            println("Transaction declined.")
            // Perform actions based on the declined state
        }
        else -> {
            // Handle other transaction states if necessary
            println("Transaction state: $state")
        }
    }
}

// Simulated usage of request and response handling
fun main() {
    // Build transaction request
    val transactionRequest = buildTransactionRequest()

    // Simulate async processing and response handling
    CoroutineScope(Dispatchers.Default).launch {
        val pxpPosSdk = com.pxpfinancial.sdk.pos.Transaction("http://127.0.0.1:8080", "YOUR_API_KEY")

        // Process the transaction
        val result = withTimeoutOrNull(10000L) { // 10 seconds timeout
            suspendCancellableCoroutine<TransactionResponse?> { continuation ->
                pxpPosSdk.processTransaction(transactionRequest) { response ->
                    continuation.resume(response, onCancellation = null)
                }
            }
