# chat_cancel_target_not_found

> The chat completion ID does not exist for this team.

**Code**: `chat_cancel_target_not_found`
**HTTP status**: `404`
**Type**: `not_found`

## When it fires

`POST /v1/chat/completions/{id}/cancel` was called with an `id` that doesn't exist for the requesting team. Same Stripe-style stance as image / video 404s — no existence leak across teams.

## How to recover

Verify the `id` you're passing came from a `POST /v1/chat/completions` response your team made. Don't retry — the resource doesn't exist (or isn't yours).
