GraphQL checkout tutorial

Step 3. Add products to the cart

GraphQL supports two types of product which can be added into shopping cart:

  • simple product
  • virtual product

If you add a product to the shopping cart as a registered customer, be sure to send the customer’s authorization token in the Authorization parameter of the header. See “Get customer authorization token” for more details.

{ CART_ID } is the unique shopping cart ID from Step 2. Create empty cart.
