PCI Booking’s outbound IP addresses, for whitelisting with third parties (PSPs, channel managers, hotel PMSs).
When PCI Booking makes an outbound call on your behalf - processing a payment through a PSP, relaying a request to a third party, or forwarding data to your own API - the request originates from PCI Booking’s infrastructure. Some third parties require these addresses to be whitelisted before they’ll accept traffic; without it, you’ll typically see a 401, 403, or a generic “not allowed from there” style rejection at the third party.
Current IP Addresses
54.76.6.4454.154.67.2434.243.40.17752.212.21.4
These addresses are fixed. They apply to both sandbox and live accounts, because both types of account run in PCI Booking’s production environment.
The addresses can change in the future. If a third party starts rejecting requests from PCI Booking, check this page first for the current list.
Ports
By default, PCI Booking sends requests only to standard secure ports. If your target uses another port, ask support to open it. Each request goes through an approval process at PCI Booking and needs a business justification.
When You Need This
Configuring a PSP’s firewall/whitelist so PCI Booking can reach their API through the Universal Payment Gateway.
Using Token Replacement in Request to send card data to a third party that only accepts traffic from known IP addresses.
