Description
We have a chatbot which resides in our corporate data center with a firewall to permit only known inbound communication.
Our Info Security team wants to implement an IP address filter to secure the Zoom Platform to a chabot Bot End Point. Where can we find a list of IP addresses that are used by Zoom for this purpose?
Note that the lists available here: https://support.zoom.us/hc/en-us/articles/201362683-Network-firewall-or-proxy-server-settings-for-Zoom are for Zoom Client to Zoom Platform communication. This is Outbound from our data center to Zoom.
The list we desire is in the opposite direction, from Zoom Platform to ChatBot End Point, inbound to our data center, plus list of any IPs used by any other webhook flows.
