Do I need a backend server of my website to use the developer API

[turica_milan]

Hi,

I'm following a tutorial to use paypal as a payment gateway.

My website is a Hostinger hosted WordPress site.

Hostinger does not support backend servers and instead offers VPS to run anything on the backend. I do not have a VPS plan on top of my web hosting plan.

Do I need to buy this service or can I run the code accessing PayPal API on the client, as I have been doing for the rest of the page.
