# Headless

The Headless API is recommended to build quality projects with a long lifetime. It is designed to complete a transaction, from creating a Cart all the way to placing the order.

## Postman collection

The Postman collection is the perfect starting point. It contains a list of all available endpoints and can generate code examples for different languages/frameworks. It's our strong recommendation to supplement our documentation with the collection below.
