The /voidTransaction method is used to cancel Sales/Credits/APM requests/transactions during the short time window between submitting the Sale/Credit/APM request and the moment that the Sale/Credit/APM transmission is passed. For example, in the best-case scenario, voiding may only be possible up to 24 hours after submitting the Sale/Credit request.

When sending a /voidTransaction request, you must provide the relatedTransactionId (which is the original Sale/Credit/APM transactionId) and the authCode.

Example /voidTransaction Request

{
    "merchantId": "<your merchantId>",
    "merchantSiteId": "<your merchantSiteId>",
    "relatedTransactionId": "<transactionId returned from /payment>",
    "amount": "200",
    "currency": "USD",
    "urlDetails": {
     "notificationUrl": "<notificationURL>"
    },
    "clientRequestId": "<unique request ID in merchant system>",
    "clientUniqueId": "<unique transaction ID in merchant system>",
    "timeStamp": "<YYYYMMDDHHmmss>",
    "checksum": "<calculated checksum>"
}

//Initialize the SDK (see https://docs.nuvei.com/?p=53233)

<?php
//voidTransaction
$voidResponse = $safeCharge->getPaymentService()->voidTransaction([
    'clientUniqueId'          => '<unique transaction ID in merchant system>',
    'amount'                  => '200',
    'currency'                => 'USD',
    'relatedTransactionId'    => '<transactionId returned from /payment>',

    String clientRequestId = "<unique request ID in merchant system>";
    String currency = "USD";
    String amount = "200";
    String relatedTransactionId = "<transactionId returned from /payment>";

    Safecharge safecharge = new Safecharge();
    SafechargeResponse response = safecharge.voidTransaction(clientRequestId, relatedTransactionId, amount, currency, null, clientUniqueId, null, null, null, null, null, null);

    clientRequestId: "<unique request ID in merchant system>",
    clientUniqueId: "<unique transaction ID in merchant system>");

//Initialize the SDK (see https://docs.nuvei.com/?p=53443)

safecharge.paymentService.voidTransaction({
    clientRequestId     : "<unique request ID in merchant system>",
    clientUniqueId      : "<unique transaction ID in merchant system>,
