Do i have to pay premium for callback to work?

Im trying to use external POST/GET but it seems like infinity free is blocking them

Premium hosting indeed doesn’t block such requests.

hello, so ive upgraded to the 5.99$ version on ifastnet, how long does it take for it to work, cuz it stills shows free version on infinity free, i did it llike 10 hours ago

You need to ask iFastNet to do the migration for you. In short, while it is called an “upgrade”, you’ll end up get two accounts, one free and one premium.
