We are doing a ServiceNow/Slack integration and created a scripted REST service that Slack requests from. However, these requests technically are coming from Slacks servers who use AWS. Their IP addresses are dynamic and constantly changing.
Because we have IP restrictions on our instance, no matter which IP addresses we whitelist, the integration will stop working when the Slack servers IP addresses change. I was instructed we could whitelist a series of their domains (Slacks) and this would fix the issue. Is it possible to whitelist domains in ServiceNow instead of IP addresses?
