# Delete a project (idempotent)

DELETE

/v1/projects/{projectId}

```sh
curl --request DELETE \
  --url https://example.com/v1/projects/example \
  --header 'Authorization: Bearer <token>'
```

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.1.9/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**projectId**

required

string

ProjectId — opaque branded string.

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per `docs/API-ROUTE-CONVENTIONS.md` §3.1). A retry sent while the first request still runs is answered `409 idempotency-key-in-flight` with `Retry-After`, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets `409 idempotency-key-replay-withheld`, with the first request’s status and when it succeeded (from 0.1.5).
