# `IDEMPOTENCY_KEY_IN_PROGRESS`

## Description

The server has a request with this idempotency key in progress.

## HTTP Status

`409 Conflict`

## `doc_url` Format

`<docs-base-url>/errors/idempotency_key_in_progress`

## Example

```json
{
  "errors": [
    {
      "code": "IDEMPOTENCY_KEY_IN_PROGRESS",
      "message": "A request with this idempotency key is still in progress.",
      "doc_url": "https://docs.example.com/errors/idempotency_key_in_progress"
    }
  ]
}
```

## How To Fix

Wait a few seconds, then retry with the same key and request body.

If the server returns this error after two minutes, use a new key. Quarzo will
check ZITADEL for the existing user before it sends another invitation.
