Easily add URLs to NextDNS allow/denylist from iOS and Mac
I have previously mentioned that I love NextDNS, but they do not make certain fundamental things, like managing your block and allow lists, very easy. Quite often I'll hit a URL that's blocked that I'd like to see - rather than use their app, I have to load their (completely desktop-oriented) website, navigate to the right tab, then add the URL in.
That's annoying.
Without writing an iOS app all of its own (which sounds like a lot of work), I wanted an easy to way to push URLs to the block or deny list. So I wrote an iOS Shortcut that works with a PHP script to send the appropriate messages.
You can find the shortcut here.
The PHP script can found at this Gist. You'll need to set the token, API key (API key can be found at the bottom of your NextDNS profile) and profile ID variables in the script. The token is what you'll use to secure your requests from your phone to the server.
I thought about offering a generic PHP server that required you to set everything in Shortcuts, but that's inherently insecure for everyone using it, so I decided against it. I think it would be possible to do this all in Shortcuts, but Shortcuts drives me nuts for anything remotely complex, and this does what I need it to.
It really is annoying how hard it is to manage a basic function. NextDNS also doesn't seem to have set their CORS headers properly for OPTIONS requests, which are required for browser-based interactions because of how they dictated the API token has to be sent.
