Reply To: how to make a button?

Hello,

Please consider the option using the affiliate product type by Wocommmerce, this functionality has been already provided https://docs.woocommerce.com/document/affiliate-for-woocommerce/

Alternatively, You will have to create an HTML block with a button and unique link for each product https://xtemos.com/docs/woodmart/html-blocks-2/ and add it as the Extra block: https://xtemos.com/docs/woodmart/product-page-options/#local_settings
