# Create cart

POST `/cart`

This endpoint lets you to create a cart with a unique identifier for each of your users. 

The unique identifier for all cart requests is the user's Object Id. Here's a [generator and helper function](https://observablehq.com/@hugodf/mongodb-objectid-generator) you can use. You do not need to register a user beforehand. When you do a request to /cart, just pass in the new user's Object Id. You'll then use the same Object Id for subsequent requests to add more items to the cart, get a cart, and create an order.

If the product you're adding to the Request Body has a variant, then pass in the Variant Id. If the product doesn't have any variants, you pass in the Product Id as the Variant Id.
