Product Customer-Group Prices — Update (GraphQL)

Updates an existing customer-group (tier) price row. This is a parent-scoped mutation — pass the product as the productId argument and the row IRI as input.id. Send only the fields you want to change. The new qty / customerGroupId combination must remain unique for the product. A null customerGroupId makes the price apply to every customer group.

See the Products overview for how the catalog product menu fits together.
