# Cancel a booking

`POST /v1/bookings/{uid}/cancel`

Soft-deletes a single booking: status flips to `cancelled`, `cancelled_by` records the acting member, the optional `reason` lands in `cancellation_reason`, and `ical_sequence` jumps by 100. The freed slot becomes bookable again immediately. Authorized for the booking's organizer, any of its hosts, and workspace owners/admins. Series cancellation rides with recurring bookings (WIBLO-132). Per-user rate-limited at 30/60s.

## Path parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `uid` | `string` | Yes |  |

## Headers

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `X-Wiblo-Workspace` | `string` | Yes | Workspace id the call is scoped to. The actor must hold an active membership in it; a foreign or unknown id collapses onto 404 WORKSPACE_NOT_FOUND. |

## Request body

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `reason` | `string` | No | Optional cancellation reason (max 500 characters); it lands in the booking's `cancellation_reason`. |

## Responses

**`200`** — The booking was cancelled (idempotent — cancelling an already-cancelled booking succeeds again). Returns `CancelBookingResponse`.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `booking` | `object` | Yes | The cancel outcome. |
| `booking.booking_id` | `string` | Yes | Unique id of the cancelled booking. |
| `booking.booking_uid` | `string` | Yes | Public uid of the cancelled booking. |
| `booking.status` | `"cancelled"` | Yes | Always `cancelled`. |
| `booking.cancelled` | `boolean` | Yes | `true` on success — the booking's status flipped to `cancelled`. |
| `booking.message` | `string` | Yes | Human-readable outcome message. |

**`400`** — Body failed Zod validation or the `X-Wiblo-Workspace` header was missing (`VALIDATION_FAILED`). Returns `ApiErrorEnvelope`.

**`401`** — No valid session cookie or `wbl_*` bearer was present. Returns `ApiErrorEnvelope`.

**`403`** — The actor is neither the booking's organizer, one of its hosts, nor an owner/admin (`BOOKING_FORBIDDEN`). Returns `ApiErrorEnvelope`.

**`404`** — No booking with this uid in this workspace (`BOOKING_NOT_FOUND` — cross-workspace uids collapse here) or the workspace collapsed (`WORKSPACE_NOT_FOUND`). Returns `ApiErrorEnvelope`.

**`429`** — Rate limit exceeded. The body's `error.code` is `RATE_LIMITED` and `error.details.retry_after` is the same number of seconds as the `Retry-After` header. Returns `ApiErrorEnvelope`.
