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

​
When to use

  • A brand owner needs to set or replace the verbatim ingredient-list text printed on a product’s packaging.

​
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

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 used by edit-product-basic-info, edit-product-dimensions, and edit-product-classification — a single request can combine fields from all four.
