is there a possibility through the API to get this value DDOS_Attack counter?
I haven’t heard of this before. Where are you seeing this in Firewall Rules?
Thanks for attaching, as @sdayman mentioned, it looks like this might be a User-Defined Firewall rule, so the name showing here looks to be a user-defined value.
Regarding retrieving via an API call, this should indeed be possible using our Firewall GraphQL Analytics endpoint.
Does this by chance help?
