If you are looking to share product links to your customers so that they can go directly to the product page and checkout via Mini App, you can use the "Product Ref Link" feature on Product Manager.
To access the Product Ref Link/URL, just click the Product Ref Link on the Product Entry. Then copy the Product Ref Link and start sharing it with your customers.
