Programmatic equivalent of the dashboard’s products/<gtin>/classification/ page.

​
When to use

  • A brand owner needs to set or correct a product’s GS1 GPC segment, family, class, or brick code.

​
Auth

X-API-Key header or OAuth token with products:write scope. The caller must be an OWNER, MANAGER, or EDITOR on the organization that owns the GTIN.

​
Flow

Every field is optional; omit or send null to leave unchanged. Returns 200 with the updated ProductOut, 403 for a caller without the required role, 404 if the GTIN isn’t owned by the caller’s organization. This is the same PATCH endpoint as edit-product-basic-info and edit-product-dimensions — the dashboard splits it across three pages, but a single request can set fields from all three at once.
