Item Attributes Realtime-enabled
GETTable: Item Attribute Value Mapping
eOne/core/v1.0/itemAttributes
A read-only feed that flattens Business Central's EAV attribute model into flat name/value/unit columns, so you do not have to join attribute, option, and value tables yourself. It exposes resolved attributes for items, both directly assigned and category-inherited.
The underlying table also stores attribute mappings for item categories and variants; this endpoint pins its source view to Table ID = 27 (Item), so only item-level attribute mappings surface here.
Reading attributes
GET/itemAttributes
It is also available as the expandable child collection of the Items endpoint, so you can pull an item and its attributes in one call:
GET/items?$expand=itemAttributes
The typed columns
value, numericValue, and dateValue are populated according to the attribute's data type, only the column matching the attribute type carries a value.This endpoint has no
integrationId and is not writable. POST, PATCH, and DELETE are all blocked. Manage attribute assignments in Business Central; consume them here.itemId is a resolver column computed per row from the item's No.. It is read-only and cannot be filtered as an indexed key.
