# Reschedule a booking

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

Moves a single booking to a new slot. The new slot validates with the creation semantics — host conflicts widened by the service's buffers, out-of-office blocks, and booking/duration limits that EXCLUDE the booking being moved from its own count. On success the times move, `rescheduled_by` records the acting member, `ical_sequence` increments, and the idempotency key regenerates. Round-robin services with `reschedule_with_same_rr_host = false` reassign the host atomically with fresh fairness selection — the booking keeps its uid, status, and attendees; when every candidate conflicts the booking is left untouched and the call answers 409. Same authorization as cancel. 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 |
| --- | --- | --- | --- |
| `start_time` | `string` | Yes | New slot start as an RFC 3339 datetime; UTC and offset forms accepted. |
| `end_time` | `string` | Yes | New slot end as an RFC 3339 datetime; must be after `start_time`, and the duration must match the service length. |

## Responses

**`200`** — The booking was rescheduled. `booking_uid` always matches the path uid — fresh-host reschedules reassign the host atomically on the same booking. Returns `RescheduleBookingResponse`.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `booking` | `object` | Yes | The reschedule outcome. |
| `booking.booking_id` | `string` | Yes | Unique id of the booking. |
| `booking.booking_uid` | `string` | Yes | Public uid of the booking — always the SAME uid: fresh-host reschedules reassign the host atomically on the same booking. |
| `booking.member_id` | `string \| null` | Yes | The assigned organizer's workspace member id after the reschedule (fresh-host reschedules may change it); `null` only for history rows whose organizer edge was severed. |
| `booking.status` | `"accepted" \| "pending"` | Yes | The booking's status — kept across the reschedule. |
| `booking.rescheduled` | `boolean` | Yes | `true` when the booking was moved to the new slot. |
| `booking.new_start_time` | `string` | Yes | The booking's new start (RFC 3339). |
| `booking.new_end_time` | `string` | Yes | The booking's new end (RFC 3339). |
| `booking.message` | `string` | Yes | Human-readable outcome message. |

**`400`** — Body failed Zod validation, the booking is cancelled/rejected, the duration no longer matches the service length, the new start is in the past, or the minimum booking notice is violated (`VALIDATION_FAILED` / `BAD_REQUEST`). 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`) or the workspace collapsed (`WORKSPACE_NOT_FOUND`). Returns `ApiErrorEnvelope`.

**`409`** — The new slot conflicts (`BOOKING_CONFLICT` — host busy, out of office, attendee already booked, or every round-robin candidate taken) or a booking/duration limit is full (`BOOKING_LIMIT_REACHED`). 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`.
