Review the following considerations before using the standard cart APIs.

Entity filters on the orders, assets, orderlineitems, Product, PriceBookentry, and ProductChildItem objects are supported. All advanced rules are supported.
Entity filters and advanced rules may not work as expected if the formula field is modified in the transaction. To rerun the advanced rules once the formula field is updated, execute getCartsItems API call with validate = true.
In the addToCart API, the includeAttachment input parameter is not supported.
For better performance when you use this API to add a child bundle with a parent as a virtual line item, pass rootLineItemId in the items object.

Following is an example payload.

The nameResult node is not be present in response (like attributeCategories, productAttributes) for all the standard cart APIs. The data nodes are directly present.
The structure of response for all the standard cart APIs, when called using Apex Remote Service (CpqAppHandler), is as follows:

Set price to false in getCartsItems if you don't need to run a pricing engine for the API call. This can improve performance.
For priceCart API, setting limitScopeToPassedItem no longer required to be separately passed, just pass items in the items parameters.
The replaceOffers API does not support complex transformations. For example, Multi-play offers.
Using Field Settings to add custom fields to cart is currently not supported. If any custom field is needed in API response, then it must be passed with fields parameter of request body.
Following API parameters are not supported.
- noResponseNeeded
- maintainAssetPrice

There are two invocations that can be used upon calling AssetToOrder API. Upon calling OmniFDOWrapper, the classic flow is invoked. The standard flow is invoked upon calling REST API.
The following CPQConfiguration settings are not currently supported for AssetToOrder. While we offer the functionality, there is no specific configuration available to control the API behavior for these settings:
- UsingPromotions
- DeltaPrice
- IsCachingEnabledForAssetToOrder
