# Shift a recurring series by a time offset

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

Shifts every future occurrence of the recurring series by `start_time_offset_minutes` (±24 hours), optionally only occurrences at or after `reschedule_from`. Each occurrence moves through the single-reschedule semantics — validation, buffer-widened conflicts, out-of-office blocks, limits excluding the moving row, and the round-robin `reschedule_with_same_rr_host` flag — so a blocked occurrence lands in `failures` with its original time intact while the rest of the series moves (partial success). A non-recurring booking answers 400. 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_offset_minutes` | `integer` | Yes | Minutes to shift every future occurrence by, −1440 to 1440 (±24 hours); negative shifts earlier. |
| `reschedule_from` | `string` | No | Only shift occurrences starting at or after this UTC datetime; omitted shifts every future occurrence. |

## Responses

**`200`** — The shift ran. `rescheduled_count` moved; `failures` lists the occurrences that could not move, with reasons. Returns `RescheduleBookingSeriesResponse`.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `series` | `object` | Yes | The series-shift outcome. |
| `series.rescheduled_count` | `integer` | Yes | How many occurrences moved. |
| `series.failed_count` | `integer` | Yes | How many occurrences could not move. |
| `series.failures` | `array<BookingSeriesRescheduleFailure>` | Yes | The occurrences that could not move, with reasons; their original times are untouched. |
| `series.message` | `string` | Yes | Human-readable outcome message. |

**`400`** — Body failed Zod validation (offset beyond ±24h), this booking is not part of a recurring series (`BAD_REQUEST`), or the `X-Wiblo-Workspace` header was missing (`VALIDATION_FAILED`). Returns `ApiErrorEnvelope`.

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

**`404`** — No booking with this uid in this workspace, or no future occurrences remain to shift (`BOOKING_NOT_FOUND`), 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`.
