# CONFIRMATION_EXPIRED

> HTTP 409 — Confirmation expired

**HTTP status:** 409 · **Title:** "Confirmation expired"

## When it fires

The confirmation token is past its `confirmation_expires_at`. High-value trades have a short confirmation window (60 seconds by default; configurable per-tier).

## Why it happens

* A human-in-the-loop confirmation flow took longer than the window allows.
* A queue/worker latency between `POST /v1/trades` returning the token and the consumer calling confirm.

## How to fix

* Tighten the consumer's confirm call — ideally fire it immediately after receiving the token.
* For human-in-the-loop flows that need longer, request a per-key window extension (mm tier customers who pipeline trades through human review get longer windows).
* The trade is automatically cancelled when the window expires — re-create it to retry.
