How to check if more than 1 constant is defined?

Hey Guys!

 

I am trying to check to see  if more then one constant is defined before processing a payment. However I cant seem to find a way to check if API and transaction_key

 constant is defined. Below is the code I am trying to work, so far I just have one constant defined Any help would be super apperciated.

define("API", "API_LOGIN");
define ("transaction_key", "TRANSACTION_KEY");

if(defined("API" )) {

$amount = '10.00';
$card_number = '4007000000027';
$exp_date = '10/16';

$transaction = new AuthorizeNetAIM(API, transaction_key);
$transaction->amount = $amount;
$transaction->card_num = $card_number;
$transaction->exp_date = $exp_date;

}
