try {
    $transactionResponse = $transactionRequest->send();
} catch (CMPayments\IDeal\Exception\ResponseException $e) {
    // Handle an error response here
    var_dump($e->getSuggestedAction());
    exit();
}

// Store these values in your local database:
$entranceCode = $transactionRequest->getEntranceCode();
$transactionId = $transactionResponse->getTransactionId();

// redirect the user to the bank environment
header('Location: ' . $transactionResponse->getAuthenticationUrl());

Validate the iDEAL transaction status on return:, _(*7)

<?php

// retrieve and sanitize transaction id from the querystring
$transactionId = preg_replace('/[^0-9]/','',$_GET['trxid']);

// at this point the entrance code ($_GET['ec']) should be checked against
// the value that was returned upon creation of the transaction

// Request the transaction status.
$statusRequest = $ideal->createStatusRequest($transactionId);
$statusResponse = $statusRequest->send();

// Get the transaction status.
switch ($statusResponse->getStatus()) {
    case \CMPayments\IDeal\IDeal::SUCCESS:
        // consumerIBAN and consumerName are available on 'Success'.
        $consumerIban = $statusResponse->getConsumerIBAN();
        $consumerName = $statusResponse->getConsumerName();
        break;
    case \CMPayments\IDeal\IDeal::OPEN:
        // When the transaction status is still 'Open' it should be retried later.
        // According to the iDEAL implementation guidelines the next attempt should only be performed after 5 minutes.
        // In total, 5 attempts are allowed and only if a non final status is returned.
        break;
    case \CMPayments\IDeal\IDeal::FAILURE:
    case \CMPayments\IDeal\IDeal::CANCELLED:
    case \CMPayments\IDeal\IDeal::EXPIRED:
        // The transaction has failed with either a Failure, Cancelled or Expired status
        // This is the moment where the user needs to be informed and the transaction should possibly be retried.
        break;    
}
