Hello @oranges13, I'm using CloudFlare as well in some of my projects, and I can't reproduce the issue.
Did you try to contact CloudFlare support team and ask them to check why it is being blocked?
There might be an issue with the configuration of CloudFlare.
This seems to happen when caching in general is activated. I have W3 Total Cache installed and experienced the same 400 error on admin_ajax.php. I disabled W3TC and the error went away. Something that this slack notifications plugin is doing seems to trigger this.
Our site is protected by cloudflare, and the "run test" button on the general settings page does not work. Behind the scenes, there is a 400 error on the admin_ajax.php page.
If I disable cloudflare, or place it into Development mode, it works.
I haven't had any issues with other plugins using the WP API.
