Once you have created products you can then share them to your customers.

Each product has a unique checkout URL, which opens a checkout ready for purchase.

You can get the checkout URL for each product by clicking on "Share" buttons in your dashboard. From the Share page you'll see options for configuring the checkout.

You can also get checkout URLs from the API by creating a checkout.

As soon as a checkout URL (/checkout/buy/...) is opened in a browser, it is converted to a "cart" (/checkout/?cart=...). These cart URLs should not be shared because they are designed to be single-use and unique to a customer.
