Creating a transaction

When creating a transaction, pass the exchangeRateQuoteId from the PHP SDK.

The Exchange Rate Quote API is a GraphQL API, and the server-side implementation includes converting the below request passed to the API.

The client-side makes a request by passing the following variables:

PHP

$variables = [
    "quotes" => [
        "baseCurrency" => "USD",
        "quoteCurrency" => "EURC",
        "baseAmount" => "12.19",
        "markup" => "1.89",
    ],
];
$request = ExchangeRateQuoteRequest::factory($variables);

and invoking the API:

PHP

$response = $gateway->exchangeRateQuote()->generate($request);

the response:

PHP

$result = $gateway->transaction()->sale([
    'amount' => '10.00',
    'paymentMethodNonce' => $nonceFromTheClient,
    'deviceData' => $deviceDataFromTheClient,
    'exchangeRateQuoteId' => $exchangeRateQuoteIdFromTheClient,
    'options' => ['submitForSettlement' => True]
]);
