Creating a Guest Cart in Magento 2 Using the REST API

When building e-commerce stores with Magento 2, one of the common use cases is allowing customers to add products to their shopping carts without the need to register or log in. This is particularly useful for guest users who prefer a quicker checkout process. In Magento 2, you can create and manage guest carts through the REST API, making it easier to integrate with mobile apps, third-party systems, or other platforms.

Creating a Guest Cart in Magento 2 Using the REST API

To create a guest cart in Magento 2 via the REST API, follow these steps:

Send a POST Request to Create the Cart

Endpoint

POST <WEBSITE_URL>/rest/<STORE_CODE>/V1/guest-carts

Replace <WEBSITE_URL> with your site's URL and <STORE_CODE> with your store's code.

Headers:

Content-Type: application/json

No authentication token is required for guest users.

  • Payload: An empty payload is sufficient.
  • Response: The response will include a masked_id, a random string representing the cart.
  • Example response:

    "fQtl1bxLdxud1fFEP68znOAPnAFFpjVh"

    This masked_id corresponds to the quote_id_mask in the database.

    Payload: Include the product SKU, quantity, and the quote_id (which is the same as masked_id).

    Example payload:

    {

    "cartItem": {

    "sku": "product-sku",

    "qty": 1,

    "quote_id": "fQtl1bxLdxud1fFEP68znOAPnAFFpjVh"

    }

    }

    By following these steps, you can programmatically create a guest cart and add items to it using Magento 2's REST API.
