Attributes API reference
# Attributes
Use the section that matches your caller: storefront clients use Shopper REST or Search, trusted services use Management, and signed-in customer flows use Auth.
Use Attributes when the job is about reusable structured values and their relationships to catalog items, users, or organisations.
Management API attribute operations own template-scoped attribute creation, updates, deletion, field-value deletion, linked attributes, item relationships, and bulk attribute or relationship changes. Auth API attribute routes expose user and organisation attribute reads or relationship changes in customer/account context.
Use attribute relationship operations when an existing attribute is being attached to or removed from another resource. Use attribute create/update/delete operations when the attribute value itself is changing. Use Attribute Templates when the field model is changing.
