# idempotency-in-progress

`https://ckrets.ai/problems/idempotency-in-progress` is a problem type of the ckrets.ai API (RFC 9457: the body is
`application/problem+json` with `type`, `title`, `status` and `detail`; every problem from `/v1` also carries `requestId`).

| Status | Also in the answer | What to do |
|---|---|---|
| 409 | (`retryable: true`, `Retry-After: 1`) | a create with this `Idempotency-Key` is still running: send the same request again after `Retry-After`; it then gets the first answer |

Every type, with its retry rule and headers: [limits.md, "Errors, retries and headers"](/limits.md#errors-retries-and-headers).
