# PUT /SurgicalRecords/{id}/events/{eventId}

`PUT /SurgicalRecords/{id}/events/{eventId}`

## Path parameters

- `id` string, required
- `eventId` string, required

## Request body

- UpdateSurgicalTimelineEventRequest
  - `title` string, nullable
  - `details` string, nullable
  - `isPinned` boolean, nullable
  - `occurredAt` string, date-time, nullable — Corrected time the step actually happened, UTC. Omit to leave the stamp alone. A value that differs from the stored stamp appends a `SurgicalTimelineEventAmendment`; it is never a silent overwrite.
  - `amendmentReason` string, nullable — Optional justification recorded alongside an DateTime? UpdateSurgicalTimelineEventRequest.OccurredAt correction.

## Response `200`

    - `reason` string, nullable
