Mapping menu feeds and fulfillment cart items
When customers add items from your Menu feed into their cart and check out, Google sends those items to your fulfillment endpoint to verify their price and availability. Once pricing and availability are validated, the customer can place the order. This section illustrates how to map menu feed items to fulfillment cart items.
Samples in this section are stripped-down versions of the Menu feed and the Cart
schema. Only fields relevant to illustrate the mapping between the Menu feed and
the Cart object are shown. For full schemas, see Menu and Cart.
Items in the Menu feed that are added to a cart are sent in the Cart
object for both checkout and order submission.
- A simple
MenuItemis represented as aLineItemin thelineItemsarray with theofferIdbeing the selected menu item'soffer.idin the Menu feed. - A
MenuItemwith a requiredMenuItemOptionis represented as aLineItemin thelineItemsarray with theofferIdbeing the selected menu item option'soffer.idfrom the Menu feed. - An
AddOnMenuItemof aLineItemis represented as aFoodItemOptionin theoptionsarray of theFoodItemExtension. Each option has anofferIdthat corresponds to the selected add-on menu item'soffer.idfrom the Menu feed. Note that an AddOnMenuItem can also have nested AddOnMenuItem(s) that are represented assubOptionsinside each option.
The following examples map menu items between the menu feed and fulfillment cart.

Handling errors
If you experience issues while processing a CheckoutRequestMessage, you
can respond with a CheckoutResponseMessage that contains a
FoodErrorExtension rather than a CheckoutResponse. You can use this
response to identify one or more errors that occurred during processing.
There are 2 ways to handle the errors:
- Recoverable errors: The user is not required to edit their cart to submit the
order. For example, if you determine that an item in the
Carthas a price change, you can respond with aFoodOrderErrorof error typePRICE_CHANGED, along with thecorrectedProposedOrderandpaymentOptions. Google informs the user of the change but lets the user submit with thecorrectedProposedOrder. The user can also go back and edit their cart if desired. You will either receive a newCheckoutRequestMessageor aSubmitOrderRequestMessage. - Unrecoverable errors: The user is required to edit their cart before
submitting the order. For example, if you determine that the restaurant is
closed, you can respond with a
FoodOrderErrorof error typeCLOSED. Google informs the user and manages the interaction to update to a new restaurant. You will receive a newCheckoutRequestMessagefor a new cart.
In general, make cart-level errors unrecoverable and item-level errors
recoverable. For a complete list of error types and their meanings, see
FoodOrderError.
Handling price changes
Price changes during checkout
If you encounter a price issue while processing a customer's checkout request, do the following:
- Respond to the
CheckoutRequestMessagewith aCheckoutResponseMessagethat contains aFoodErrorExtension, as described in Handling errors. - In the error response, use
correctedProposedOrder.cartto update the price to the correct value. Google receives the corrected order and may issue a newCheckoutRequestMessage.
After checkout, Google displays an order confirmation page to the end user,
regardless of whether the ProposedOrder was changed or not.
If the ProposedOrder was corrected, Google may show additional warnings to
inform the user of the changes. If the user agrees to place the order, there
will be no more checkout requests. The flow continues to order submission, with
the corrected ProposedOrder.
However, the user can always change their mind and edit their cart again. When
their cart updates in this way, Google sends a new CheckoutRequestMessage.
Price changes during submit order
If you encounter a price issue while processing order submission
(the actions.intent.TRANSACTION_DECISION intent was triggered), don't respond
with an error or update the price in your response. If the prices, quantities,
or other details in the SubmitOrderRequestMessage do not correspond with
your data, respond with the orderState set to REJECTED to indicate that the
order cannot be placed as requested.
Then, if the order and payment details are valid, set orderState to CREATED
or CONFIRMED. Also, include an actionOrderId to represent the order's ID in
your system. This ID must be used when sending subsequent updates.
If you are unable to process the payment and have already sent the
SubmitOrderRequestMessage, you can send an
AsyncOrderUpdateRequestMessage with orderState set to REJECTED to let
the user know that the order will not go through.
Price changes after submit order
If you determine that a price has changed from the price used when a customer
submitted their order, you can issue an AsyncOrderUpdateRequestMessage, as
described in Implementing Asynchronous Order Updates, with the new price.
To update prices using async order updates:
- Change the price in
lineItemUpdates[x].price. This value reflects the total cost of the item, including add-ons and multiplied by the quantity. (For more information, see the description of thepricefield ofLineItem.) - Enter an explanation in
lineItemUpdates[x].reason. - Set
lineItemUpdates[x].orderStatetoCONFIRMED.
You can attempt to charge the payment instrument before or after sending the
AsyncOrderUpdateRequestMessage, at your discretion. If the transaction fails
(possibly because the price delta is too high), send an
AsyncOrderUpdateRequestMessage with the following settings in the
OrderUpdate to inform Google of the failure:
- Set
orderStatetoREJECTED. - Describe the failure in the
labelfield.
Checkout validation
As discussed in Step 4: Implement Checkout, your
fulfillment endpoint should perform validation on every incoming
CheckoutRequestMessage, and respond with a CheckoutResponseMessage.
Here's an example of a CheckoutResponseMessage for a successful
validation:
| Use case | How to implement |
|---|---|
| Use case 1: Validation is successful | Return CheckoutResponse. It must have
ProposedOrder and PaymentOptions.
ProposedOrder includes tax, fees, and the total price of the
cart. |

Delivery address validation
Your fulfillment endpoint should validate the delivery address contained in each
CheckoutRequestMessage.
If there's an issue with the delivery address, such as it being out of range of
the delivery service, the CheckoutResponseMessage returned by your
fulfillment should contain a FoodOrderError of the appropriate type.
| Use case | How to implement |
|---|---|
| Use case 1: Validation failed because delivery address is out of range or there's an issue with the delivery address | Return FoodErrorExtension with FoodOrderError
of error type OUT_OF_SERVICE_AREA. |
JSON

{
"error": "OUT_OF_SERVICE_AREA",
"description": "Sorry, the restaurant cannot deliver to your address."
}
]
}
}
}
]
}
}
}
Minimum order value validation
Your fulfillment endpoint should validate the minimum order value of each
CheckoutRequestMessage.
If the minimum order value is not met, the CheckoutResponseMessage
returned by your fulfillment should contain a FoodOrderError of error type
REQUIREMENTS_NOT_MET.
| Use case | How to implement |
|---|---|
| Use case 1: Validation failed because the minimum order value isn't met | Return FoodErrorExtension with FoodOrderError
of error type REQUIREMENTS_NOT_MET. |

{
"error": "REQUIREMENTS_NOT_MET",
"description": "The cart subtotal must be over $20."
}
]
}
}
}
]
}
}
}
Ordering window validation
Your fulfillment endpoint should validate any factors that may affect the
ordering window of each CheckoutRequestMessage.
For example, if the restaurant is closed or no longer taking orders at the
moment, the CheckoutResponseMessage returned by your fulfillment should
contain a FoodOrderError of error type CLOSED or NO_CAPACITY,
respectively.
| Use case | How to implement |
|---|---|
| Use case 1: Validation failed because the restaurant is closed or no longer supported | Return FoodErrorExtension with FoodOrderError
of error type CLOSED. |
| Use case 2: Validation failed because the restaurant is busy and not taking orders at the moment | Return FoodErrorExtension with FoodOrderError
of error type NO_CAPACITY. |

Cart items validation
Your fulfillment endpoint should validate the pricing and availability of each
cart item contained in a CheckoutRequestMessage.
If the availability or pricing has changed, the CheckoutResponseMessage
returned by your fulfillment should contain a FoodOrderError of error type
AVAILABILITY_CHANGED or PRICE_CHANGED, respectively.
| Use case | How to implement |
|---|---|
| Use case 1: Validation failed because some menu items and/or their customizations are not valid or are out of stock | Return FoodErrorExtension with correctedProposedOrder,
PaymentOptions, and FoodOrderError of error type
AVAILABILITY_CHANGED. Invalid items must be removed from
CorrectedProposedOrder. |
| Use case 2: Validation failed because some menu items and/or their customizations are not valid or are out of stock. The corrected cart no longer meets the minimum order value requirement. | Return FoodErrorExtension with FoodOrderError
of error types AVAILABILITY_CHANGED and
REQUIREMENTS_NOT_MET. |
| Use case 3: Validation failed because some menu item and/or customization prices have changed | Return FoodErrorExtension with correctedProposedOrder,
PaymentOptions, and FoodOrderError of error type
PRICE_CHANGED. Outdated prices must be updated in
CorrectedProposedOrder. |
| Use case 4: Validation failed because some menu item and/or customization prices have changed. The corrected cart no longer meets the minimum order value requirement | Return FoodErrorExtension with FoodOrderError

Submit order validation
As discussed in Step 7: Implement Submit Order, your
fulfillment endpoint should perform validation on every incoming
SubmitOrderRequestMessage, and respond with a
SubmitOrderResponseMessage.
Here's an example of a SubmitOrderResponseMessage for a successful
validation:
| Use case | How to implement |
|---|---|
| Use case 1: Order is successfully created | A SubmitOrderResponseMessage with CREATED order
state. It must have actionOrderId,
userVisibleId, orderManagementActions, and
estimatedFulfillmentTime. |
| Use case 2: Order is rejected because of payment issues | A SubmitOrderResponseMessage with REJECTED order
state. It must have actionOrderId,
userVisibleId, orderManagementActions, and
rejectionInfo of type PAYMENT_DECLINED. |
| Use case 3: Order is rejected for user is flagged as banned | A SubmitOrderResponseMessage with REJECTED order
status. It must have actionOrderId,
userVisibleId, orderManagementActions, and
rejectionInfo of type INELIGIBLE. |
| Use case 4: Order is rejected because user information is incomplete or invalid | A SubmitOrderResponseMessage with REJECTED order
state. It must have actionOrderId,
userVisibleId, orderManagementActions, and
rejectionInfo of type INELIGIBLE. |
| Use case 5: Order is rejected for unknown reason | A SubmitOrderResponseMessage with REJECTED order
state. It must have actionOrderId,
userVisibleId, orderManagementActions, and
rejectionInfo of type UNKNOWN. |
