My boss asked if we can set up a list of IP addresses Zapier uses to connect to our Rest endpoints. So far in my review of the IIS log I found the following IP addresses in use.
Although I imagine this list changes frequently and our goal here is to lock down our Rest services so only Zapier and other 3rd parties can connect without having something or someone else be able to brute force their way in from the outside. Has anyone attempted this before and what is the normal way of going about it?

We use the dynamic range of AWS’ us-east-1 region, which are subject to change over time. AWS provides some tooling to help your team determine the current IP range of the us-east-1: https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html
I hope that helps!
