# Update a broadcast

`PATCH /broadcasts/{id}`

## Request

- Base URL: `https://api.crevio.co/v1`
- URL: `https://api.crevio.co/v1/broadcasts/{id}`
- Auth: API key in header `Authorization`

Updates a draft or scheduled broadcast. Only fields included in the request body change. Clearing `scheduled_at` demotes a scheduled broadcast back to a draft; setting it on a draft schedules it. A broadcast that is already sending or sent can no longer be edited.

## Path parameters

- `id` string, required
