Channex now offers a Channex PCI API - a solution to work with sensitive Credit Card information so you can outsource PCI DSS scope from your application to ours.
Channex PCI allow partners to exchange information about Credit Cards between any system both incoming and outgoing. Also, we support operations to show cards via iframe and collect by iframe.
This is a simple diagram of how Channex is in the middle of an API call (Proxy) and returns bookings in a PCI Compliant way.
