# Patch Schedule Intervals

`PATCH /manage/schedules`

Merge new availability and/or curtailment schedule intervals into the existing stored schedule for a premium resource. Overlapping intervals are replaced (existing intervals are split as needed). The request is all-or-nothing: a validation error in any entry rejects the entire request.

## Request Body

| Name | Type | Required | Description | Accepted Values |
| --- | --- | --- | --- | --- |
| `resource_id` | string | yes | The resource id. |  |
| `availability_schedule` | AvailabilityIntervalDto[] | no | Availability schedule entries to merge. |  |
| `curtailment_schedule` | CurtailmentIntervalDto[] | no | Curtailment schedule entries to merge. |  |
