Rasa with shopify add items to cart

Currently I have an ecommerce website using shopify. i am using rasa chatbot along with shopify api calls for displaying collections and stuffs. Now, when the product is displayed in chatbot, can i add that product directly to cart?

“image_url”: (format(PI1)), “subtitle”: (format(PN1)), “buttons”: [ { “title”: “Add to cart”, “payload”: “add”, “type”: “postback” }, { “title”: “Buy”, “payload”: “checkout”, “type”:“postbook” } ] How can I link this “Add to cart” button to my website cart?
