Activating "add to cart" button from another website

[Timoxa]

Hi everyone,

I have the main website in tilda, but I would like to use the cart from prestashop. So if I'll try to add the product from tilda to the cart of prestashop website by pushing the button 'add to cart', I need to set the link for this button on tilda's website. As I understand, fot that is required to set to tilda's button 'add to cart' the link of the prestashop's button 'add to cart', but in prestashop there is no link for this button. Does anybody have some ideas how to perform my task? thanks
