Returns a table that compares summary groups from multiple carts of the same quote. Each row represents a summary group (e.g., Subtotal, Discount, Total, Grand Total), and each cart appears in its own column. Summary groups are unioned across all carts; null values indicate a group is absent in that cart. Supports paging when there are many summary groups.

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 summary-group 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.
