A new Returns API lets you list return items and their barcode references for a given barcode across the merchants you operate, so your warehouse can identify an inbound return from the label alone.
You can now browse the noon category tree, discover exactly which attributes a category expects, submit products against it, and read back their content — four endpoints, with a guide set that takes you from first call to go-live.
The Catalog API now covers two operations you previously had to work around: deleting parent and child SKUs in batches, and loading barcodes in bulk from a file, a BigQuery table, or an inline list.
