Our Cloudflare implementation hosts many sites and when we do a push to production, we have to individually clear the cache for each domain. It would be great to have a “Clear All Caches” button in the dashboard to facilitate clearing all (or selected) domains at once. Thanks!
You could probably automate that using the API.
Each zone in your account is an independent entity. The only “all zone” setting I can think of is Firewall Tools, and I believe that’s a holdover from the very early days of Cloudflare. I’m pretty sure that will be removed now that Firewall Rules exists.
In short, as @TomKlein said, you’re going to have to implement your own process for this.
