</Warning>

Updates a loyalty program. When the program is not in `DRAFT` status, only `name` and
`metadata` may be changed (other properties are restricted after leaving draft).

## Path parameters

- `id` string, required

## Request body

- ProgramUpdateRequest — Payload for updating a loyalty program. All properties are optional. When the program is not in `DRAFT` status, only `name` and `metadata` may be changed.
  - `name` string — Program name.
  - `start_date` string, date-time, nullable — Program validity start date, in ISO 8601 date-time format.
  - `end_date` string, date-time, nullable — Program validity end date, in ISO 8601 date-time format.
  - `validity_hours` ProgramValidityHoursUpsert — Validity hours configuration. When `type` is `ANY_TIME`, `daily` must be omitted or null. When `type` is `DAILY`, `daily` is required and must contain at least one window.
    - `type` 'DAILY' | 'ANY_TIME', required — Validity hours mode. `ANY_TIME` means the program is always valid; `DAILY` restricts validity to configured daily windows.
    - `daily` ProgramValidityDailyHoursUpsert[], nullable — Daily validity windows. Required when `type` is `DAILY`; must be null/omitted when `type` is `ANY_TIME`.
      - `days_of_week` integer[], required — Days of week the window applies to. 0 = Sunday through 6 = Saturday. Items must be unique.
      - `start_time` string, required — Window start time in `HH:mm` format. If seconds are provided, they are ignored.
      - `end_time` string, required — Window end time in `HH:mm` format. If seconds are provided, they are ignored.
  - `metadata` object, nullable — Arbitrary key-value metadata. Validated against the `vl_program` metadata schema definition of the project.
