# updateRegistryItem

mutation · in the family [Selling](/reference/selling/)

## What it does

Change a registry item — usually the wanted quantity.

STAFF: edit ONE item row (desiredQty/priority/note — MUTABLE under the row's OCC): variantId never moves (the membership identity — remove + re-add). The registry must be ACTIVE (ruling); a doomed row refuses CONFLICT/IMMUTABLE. Requires the unrestricted capability. Template class (hand-derived v22).

## Who may call it

Capability area: **Selling** — Ringing sales, serving customers and issuing invoices.

- Owner
- Manager
- Associate Manager
- Sales Associate
- An API key whose scope allows `api:updateRegistryItem`

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `input` | [EditRegistryItemInput](/types/EditRegistryItemInput/) `EditRegistryItemInput!` | yes | No further notes. |

## Returns

[RegistryItem](/types/RegistryItem/) `RegistryItem!` — One desired variant on a GiftRegistry. variantId is the membership identity (IMMUTABLE — remove + re-add instead); REMOVE = doom, history preserved (re-adding TAKES OVER the doomed marker — ruling).
