# createSalePrice

mutation · in the family [Sale price](/reference/sale-price/)

## What it does

Create a new sale price — a time-boxed promotional price at your organization.

Create a SalePrice — the splice insert; requires the unrestricted capability.

## Who may call it

Capability area: **Pricing** — Prices, price schedules, promotions, coupons and the money rules of selling.

- Owner
- Manager
- An API key whose scope allows `api:createSalePrice`

## Arguments

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

## Returns

[SalePrice](/types/SalePrice/) `SalePrice!` — A sale price: ONE effective-dated price window in the parent InventoryItem schedule — the dated record-set IS the full price history. Windows are half-open \[startAt, endAt) with endAt ALWAYS present (far-future = the standing price); past the last endAt with no successor the item is NOT for sale (the LAPSE rule — enforced by the sell path; stores + normalizes). Inserts are splice-normalized: a start falling STRICTLY inside the immediately-preceding window auto-TRIMS that predecessor endAt to the new start (the ONE sanctioned in-place mutation — revisioned + evented); overlap with ANY OTHER record refuses CONFLICT/PRICE_WINDOW_OVERLAP naming the blockers. No past starts. The schedule currency is FIXED by the FIRST record; a mismatch is refused NAMED. Doom cancels a not-yet-effective FUTURE record only. startAt/endAt/price are wire-IMMUTABLE.

## Dry run

Add `dryRun: true` to the request envelope (`extensions.at`) to rehearse this call: every check runs, the write is rehearsed against the current records and nothing is stored; the answer is the refusal a real call would give, or the record it would create. Every response to a rehearsal carries `dryRun: true`, so a rehearsed record is never mistaken for a saved one.
