Long story short, we have to use cURL command line to send a AUTH request to Authorize.net to pre-auth credit card transactions.  Does anyone have an example of what the post string should look like?  Are there existing scripts already written?

Thanks, Jay

You mean something like this?  This code was written in PHP.

You'll likely want to use this manual along with the example code:

http://www.authorize.net/support/AIM_guide.pdf
http://www.authorize.net/support/CNP/helpfiles/
<?

// ... more code up here to set up order processing, etc.
 

// set a test mode?

$x_Test = "FALSE";

if (usr_GLOBALS_TESTMODE) { $x_Test='TRUE'; }
 

$hashval = "Authorize.NET Customer HASH";

$x_Login="Authorize.NET Customer Login#";

$x_Delim_Data="TRUE";

$x_Delim_Char="|";

$x_Encap_Char="";

$x_Type="AUTH_ONLY";

// customer fields

$x_Method="CC";

$x_Tran_Key = "Authorize.NET Transaction Key";

$x_Amount = sprintf("%1.2f","Amount to charge");

$x_FName = "Customer First Name";

$x_LName = "Customer Last Name";

$x_Company = "Customer Company Name";

$x_Address = "Customer Address";

$x_City = "Customer City";

$x_State = "Customer State";

$x_Zip = "Customer Zip";

$x_Phone = "Customer Phone Number";

$x_Card_Num = "Customer Card Number";

// Customer's Card Expiration Date...specific format!

$x_Exp_Date = date("m/y", mktime(0, 0, 1, $expmonth, 1, $expyear));

$x_CVV = "Customer CVV Code";
 
 

/*

Unused fields:

x_tax:#:sales tax, 0.00 formatted

x_customer_ip:15:????????????????

x_description:255:description field...hrrmmm.....

*/
 

// standard fields

$fields = "x_version=3.1&x_delim_data=$x_Delim_Data&x_delim_char=$x_Delim_Char&" .

		"x_encap_char=$x_Encap_Char&x_type=$x_Type&x_method=$x_Method&x_duplicate_window=300&" .

		"x_country=US&x_email_customer=FALSE&";
 

// customized fields

$fields .= "x_login=$x_Login&x_tran_key=$x_Tran_Key&x_test_request=$x_Test&" .

					"x_first_name=$x_FName&x_last_name=$x_LName&x_address=$x_Address&" .

					"x_city=$x_City&x_state=$x_State&x_zip=$x_Zip&x_company=$x_Company&" .

					"x_phone=$x_Phone&x_cust_id=$custid&x_invoice_num=$orderid&" .

					"x_amount=$x_Amount&x_card_num=$x_Card_Num&x_exp_date=$x_Exp_Date&" .

					"x_card_code=$x_CVV";
 

// execute CURL session to authorize.net, return in $details

$ch = curl_init("https://secure.authorize.net/gateway/transact.dll");

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$buffer = curl_exec($ch);

curl_close($ch);

// get the returned array, and set up for the hash check.

$details = explode($x_Delim_Char,$buffer);
 

// details is now an array of the return

?>
