QuantumGateway: The Evolution of Payment Processing

In Line Frames API

Use an inline frame to process transactions or update SecureVault customers without the need to ever touch, transmit or store any cardholder (credit card) data on the merchant's Web site or have any such data pass through the merchant’s servers or network. The primary benefit is a substantially streamlined process for PCI compliance.

To make things easier for integration we have a PHP script with all the functions you need. There are also several examples to look at. Please download

* Added the amount to the pass back information. (May 3rd, 2012)
* Added md5 hash to the pass back information. (May 3rd, 2012)
* Forced the quantum_iframe.php to connect via TLS 1.2 instead of web server default. (July 1st, 2018)

API Last Update August 24st, 2009

For Conneciton issues please make sure your server is sending/using tls 1.1 or 1.2. To manually fix a previous installation please re-upload the quantum_iframe.php from the file above or just after line 68 add this line.
curl_setopt($ch, CURLOPT_SSLVERSION, 6);
And then re-upload it.
