Returns a table that compares line items (products, bundles, options) from multiple carts of the same quote. Each row represents a product or hierarchy node, and each cart appears in its own column. Products are unioned across all carts; null values indicate a product is absent in that cart. Supports paging when there are many products. Bundle and sub-bundle hierarchies are preserved.

Up to 5 carts can be compared at a time.

Mandatory Fields:

• request.CartIds - required; must contain 2 to 5 unique valid cart ID GUIDs

Required Fields:

• request.PageNumber - must be greater than or equal to 1 (defaults to 1)

• request.PageSize - must be greater than or equal to 1 (defaults to 50)

Responses

• 200 OK: the paged line-item comparison is returned.

• 400 Bad Request: the request is missing/invalid (e.g. fewer than 1 or more than 5 cart IDs, duplicate cart IDs, invalid GUIDs).

• 500 Internal Server Error: an unexpected error occurred or data is still loading.
  Special Notes

• Field selection is determined by system#comparequotesettings fieldset (defaults to ["NetPrice", "Quantity"]).

• Products missing in a cart show null values in that column.

• Hierarchy (bundles, sub-bundles, options) is preserved across all carts.

• Multiple root bundles are supported and displayed correctly.
