Activate additional features at PrestaShop Social: Page button Facebook

On the Sales channels tab, configure additional features to optimize the shopping experience:

Button on your page Facebook

The button on your Facebook page lets you add a button to your Facebook page, such as Buy Now, which redirects visitors to your site.

From the "Sales channels" tab, when you click on "Add", you're redirected to your Facebook page, where I can add the call-to-action and the url of the site to which you'd like to redirect your community.
