Returns from the DoExpressCheckoutPayment API.

Cause

The currency code in the request does not match the currency code in subsequent calls.

Impact

The payment process is halted, preventing the customer from finalizing their purchase. This can lead to a poor customer experience and potentially lost sales if the issue is not resolved promptly.

Resolution

// SetExpressCheckout request
$payerDetails = [
    'PAYMENTREQUEST_0_AMT' => '100.00',
    'PAYMENTREQUEST_0_CURRENCYCODE' => 'USD',
];

// DoExpressCheckoutPayment request must match initial currency
$paymentDetails = [
    'TOKEN' => $token,
    'PAYERID' => $payerId,
    'PAYMENTREQUEST_0_AMT' => '100.00',
    'PAYMENTREQUEST_0_CURRENCYCODE' => 'USD',
];
