This submits to the sandbox (developer / test) server. Are you using a sandbox account, or a production account in test mode?


I did it with testmode true and testmode false


I am using my developer account



Add this:




I put this at the top of the php



and got this error

Fatal error: Call to a member function setSandbox() on a non-object

Are you just using the sample code(NOT the SDKs)?

If so

// posting to:
$url = "";

If your ID and Key is for production, change the url to the

If it from test account, change it to


P.S. If your ID and Key is for production, make sure you running on testmode for testing. Better yet, get a test account for testing.

You obviously have to use $transaction = new [insert class call here] before you can call the setSandbox method on it. See your sample code.

I added this code to the top of the php: require_once 'anet_php_sdk/AuthorizeNet.php'; $transaction = new AuthorizeNetSIM("$apiLoginID", "$transactionKey"); $transaction->setSandbox(true); Fatal error: Call to undefined method AuthorizeNetSIM::setSandbox()

I added this code to the top of the php:

require_once 'anet_php_sdk/AuthorizeNet.php'; $transaction = new AuthorizeNetSIM("$apiLoginID", "$transactionKey"); $transaction->setSandbox(true);



Fatal error: Call to undefined method AuthorizeNetSIM::setSandbox()              

Ok , try this instead:





define("AUTHORIZENET_SANDBOX", false);
