Hello. I have a table of clicks, it contains a visitor's token, its type, item id, seller id.
user_token | ip | product_id | seller_id
It all works like this: the visitor enters the product card, there are offers under the product card, the visitor clicks on one of the offers, his token is written, type, product id, and offer id. Then there is a redirect to the seller’s website. The question is how to determine the user who has already clicked on this proposal, having his data (token and ip).
