Custom Secure URL Endpoint
If you have 3rd parties send card details into your system directly
Some OTA and Channel Managers may push bookings directly into your system including the card numbers.
To support this you will need to setup a custom CNAME like secure.yourpms.com and point it to the Channex PCI service servers.
If you require the secure endpoint please get in touch
There is no API required for this just a setup process and tokenization profiles.
