Authorize.Net just announced their "CIM Hosted Order Page":
We are pleased to announce that we now have a new, hosted option for our Customer Information Manager (CIM) API. The hosted CIM option provides a way for you to establish a hosted connection with Authorize.Net that allows the exchange of sensitive cardholder data to take place on our secure servers instead of on your servers. With the new hosted option, CIM simplifies yet another step in the PCI DSS compliance process. The hosted CIM option is available now. For more information, including integration guides, visit our CIM page at http://www.authorize.net/cim.
Will you support this? Doing so would completely eliminate PCI issues for a WHMCS server, since the WHMCS server would no longer "process, transmit or store" the credit card number.
Not being PCI compliant is costing me about $40/month and we cannot comply since WHMCS is not PA-DSS Validated. I would love to get this albatross off my neck.
