aaP_wpdevelopmail Ooooh, FINALLY UNDERSTOOD the field values
for all other users here you go:
API User = account email address, e.g. mail@gmail.com - AApanel team, you better call it "API User Email" !
API Key = Global API Key Located in /profile/api-tokens under token keys used to access Cloudflare API. For example 4080z0z0z0z0z0zzzzzz0z0z0z0z0 - 32 alphanumeric global API key - AApanel team, you better call it "Global API Key" !
Alias = this is the API TOKEN created according to the instructions in this post above - AApanel team, you'd better call it "API token"!
