Hello, i recently connected a website with Cloudflare and was using their APO plugin. I wanted to test W3 total cache Cloudflare extension to see if there is any difference but i cant complete the authorization. When i fill in the email field and global api key i get the following error message “Can’t authenticate: Improper API token / global key length.” I ve no idea what do as i am using the email on the Cloudflare account as well as the global api key. Am i doing something wrong? Lastly, is it better to use w3 Cloudflare extension in terms of performance or is it just a convenience?

Thank you in advance for you help!
