# Remove S3 Application

`DELETE /api/v1/ledger/s3/apply/{reservation_id}`

Un-apply, freeing the tokens again. Writes no ledger transaction.

Returns the refreshed apply surface so the caller does not need a second round trip.
Returns 409 ``invoice_no_longer_editable`` once the credit line is on the draft.

## Path parameters

- `reservation_id` string, required

## Response `200`

Successful Response

- S3UpcomingInvoicesResponse — The apply surface's header plus its rows. The three header figures come straight from ``S3BalanceSummaryResponse`` and keep its names, so the apply header can never disagree with the wallet tiles. ``reserved`` is what the wireframe labels "Applied to upcoming invoices" — the UI supplies that wording; the field stays ``reserved`` because no consumption has happened yet.
