# Create a broadcast

`POST /broadcasts`

## Request

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

Creates a broadcast. Omit `scheduled_at` to save a draft, pass a future timestamp to schedule it, or pass `send_now: true` to resolve the audience and start sending immediately.

Sending a 1:1 email? Use `POST /v1/email/inboxes/{inbox_id}/messages` instead — it creates a tracked thread you can reply within.

## Headers

- `Idempotency-Key` string
