URL to Extended modules

Hello,
I have installed an extended module under ‘customers’

I named the module freewifi, I want to add some info here using API.

What should my URL be…? I tried $url = “admin/customers/freewifi” on my script but it’s not working.

Kindly assist me

Thanks

try this url: “admin/config/module/freewifi
for access to module item: “admin/config/module/freewifi--{your_module_item_id}
