Does Cronofy provide fixed IP addresses for calendar service traffic?
Cronofy uses fixed IP address when communicating with calendar servers according to the data center the calendar service is connected to.
Your application vendor will be able to tell you which data center applies to your integration so that you can set your firewall rules accordingly.
Please note that these IP addresses are only used when messages are sent from Cronofy to your servers (inbound to your firewall).
Messages sent from your systems (outbound from your firewall) to Cronofy will still need to be sent to the relevant API URI.
