I have been trying to call the CloudFlare API v4, using an example provided in their own documentation.
This is the code of the example
curl -X PUT \
cmd.exe doesn't support single quotes, to run those commands straight from the docs you can use Bash.
Bash can be enabled in Windows 10 : https://www.laptopmag.com/uk/articles/use-bash-shell-windows-10
or Git Bash comes with Git for windows: https://gitforwindows.org/
