# Marks an in-transit standalone transfer failed (the Details page's "Mark as Failed").

`POST /api/v1/transfers/{id}/fail`

## Request

- Base URL: `https://app.flexonthejob.com`
- URL: `https://app.flexonthejob.com/api/v1/transfers/{id}/fail`
- Auth: HTTP bearer

Requires `ManageTransfers` and an `Idempotency-Key` header; no body. Only a
standalone transfer in `InTransit`. Its units keep their current location and their
in-transit flags are cleared; the transfer becomes `Failed`. To record that only some
lines failed, complete the transfer with `failedLines` instead.

## Path parameters

- `id` integer, required

## Response `200`

Transfer id and confirmation message.

- ApiOperationResponse: Body of a successful workflow-style write that has no richer resource to return (assign, start, complete, void…). Id is the affected resource's id; Warning carries a non-fatal note from the service (e.g. an email that could not be sent).
  - `id` integer: Id of the resource the operation acted on (e.g. the job id).
  - `message` string, nullable: Human-readable confirmation from the service (e.g. "Job started."). May be null.
  - `warning` string, nullable: Non-fatal problem encountered while completing the operation (e.g. a notification email that could not be sent). Null when there was none.

## Other responses

- `400`: Missing `Idempotency-Key`.
- `401`: Unauthorized
- `403`: Forbidden
- `404`: No such transfer in this organization.
- `409`: A job-site or sales-order transfer, not `InTransit`, or the key's creator is unknown on this server.
- `429`: Too Many Requests
- `500`: The change could not be saved. Retry with the same `Idempotency-Key`.
