ccvs_void

string ccvs_void(string session, string invoice) 

Voids a completed transaction.

Returns:

OK on success; on error, bad invoice, duplicate invoice, invalid request, uninitialized, or unknown

Description:

ccvs_void() voids a transaction that was already processed with ccvs_sale() or ccvs_return(). session must be a valid session ID as returned by ccvs_init().

To reverse a transaction that has been authorized but not yet processed by ccvs_sale() or ccvs_return(), use ccvs_reverse() instead.

Version:

PHP 4 since 4.0.2

Example:

Void a transaction

if (($ret = ccvs_void($session, 'foo')) !== 'OK') { echo "Failed ($ret): " . ccvs_textvalue($session) . "\n"; }
