How do I find out what IPs to give, my IP doesnt stay the same? The local IP is hardly the one they want, it wouldnt make sense I think.

You could get a free dynDNS name with noip.com (you'll need to verify the domain every month by logging in) this way even if you have a dynamic ip, it automatically gets updated via the hostname if you set this in your router (most brands should be able to do this).

    That wouldn't work for this...

    A domain, a full fledged one or a free dyndns subdomain tells the world how to communicate with your ip, but it isn't involved when you talk to the world.

    When your software is hitting the API from your network, all the API sees is your IP address, it has no knowledge of any urls that may point to it.

    OP just needs to hope their IP address doesn't change regularly, and give them their public IP to whitelist.

    Seems to be working fine for my VPN tunnel I use to get access to my home network, instead of an IP, it has the hostname + port to connect to it and technically I do have a non static IP. The hostname gets resolved via noip.com in this case to an IP address.

    That's kind of irrelevant for a third party resolving where network traffic is coming from. They aren't connecting to OP, OP is connecting to them. Assuming their firewall even supports reverse DNS lookups, it'd actually resolve to something like .res.ispdomain.com or something weird. And since it's dynamic there'd be no consistent domain to give.
