Guest Checkout via Magento 2 REST API: A Step-by-Step Guide
Make it easy for your customers to place orders without registering by enabling guest checkout through Magento 2's REST API. Here's a clear, concise guide to help you set this up smoothly.
Step 1: Create a Guest Cart
Start by creating an empty cart for the guest customer. The response will give you a cart_id (also called masked_id), which is essential for the next steps.
Endpoint
POST <SITE_URL>/rest/<store_code>/V1/guest-carts
Payload: None
Response Example:
w04QKi5YeYh6CC1tTFbpY1sPNKhbrMIZ
Hold on to that cart_id—you'll need it soon.
Step 2: Check the Cart Details
Retrieve the details of the guest cart using the cart_id from Step 1.
Endpoint:
GET <SITE_URL>/rest/<store_code>/V1/guest-carts/:cartId
Replace :cartId with your actual cart_id.
Response Example:
{
"id": 1187676,
"items_count": 0,
"customer": {
"email": null
}
}
Step 3: Add Products to the Cart
Now, it's time to add items to the guest cart.
Endpoint:
POST <SITE_URL>/rest/<store_code>/V1/guest-carts/:cartId/items
Payload Example:
{
"cartItem": {
"quote_id": "1187676",
"sku": "product-sku",
"qty": 1,
}
}
Response Example:
{
"item_id": 1448307,
"sku": "24-MB01",
"name": "Item Bag",
"price": 7.99
}
Step 4: Estimate Shipping Methods
Find out which shipping methods are available based on the customer's shipping address.
Endpoint:
POST <SITE_URL>/rest/<store_code>/V1/guest-carts/:cartId/estimate-shipping-methods
Payload Example:
{
"address": {
"region": "hunza",
"country_id": "IE",
"street": ["123 Oak Ave"]
"postcode": "W34 X5Y5",
"city": "hunza",
"firstname": "John",
"lastname": "Doe",
"telephone": "123456789"
}
}
Response Example:
{
"carrier_code": "matrixrate",
"method_code": "matrixrate_1",
"carrier_title": "Select Shipping Method",
"amount": 5
}
}
Step 5: Get Payment Methods
POST <SITE_URL>/rest/<store_code>/V1/guest-carts/:cartId/shipping-information
Payload Example:
Set the shipping details and retrieve available payment methods for the cart.
Endpoint:
{
"address": {
"region": "hunza",
"country_id": "IE",
"street": ["123 Oak Ave"]
"postcode": "W34 X5Y5",
"city": "hunza",
"firstname": "John",
"lastname": "Doe",
"email": "[email protected]",
"telephone": "123456789"
},
"shipping_carrier_code": "matrixrate",
"shipping_method_code": "matrixrate_1"
}
}
Response Example:
{
"payment_methods": [
{ "code": "checkmo", "title": "Check / Money Order" },
{ "code": "cashondelivery", "title": "Cash On Delivery" },
{ "code": "adyen_cc", "title": "Credit Card" }
]
}
Step 6: Place the Order
Finally, complete the checkout by providing the payment method and billing address.
Endpoint:
POST <SITE_URL>/rest/<store_code>/V1/guest-carts/:cartId/shipping-information
Payload Example:
{
"email": "[email protected]",
"paymentMethod": { "method": "cashondelivery" },
"billing_address": {
"email": "[email protected]",
"region": "County Kerry",
"country_id": "IE",
"street": ["123 hunza St"],
"postcode": "W34 X4Y5",
"city": "hunza",
"telephone": "123456789",

"lastname": "Doe"
}
}
