Refresh Allow list using a URL?

[amityweb]

Is it possible to refresh the Dyndns allow list using a URL?

The reason is my firewalls will check every 15 minutes if my IP has changed, but in emergencies this is quite bad, but its rare, so I dont want to set it to refresh every 1 minute.

So I wondered if I can kick start this refresh externally, like from a URL or something? So in an emergency I update my IP, then I call this URL to update the allow list (I am using a Global Dyndns allow list).

Thanks

Would anyone here know if this is possible? Thanks
