# Create a broadcast draft

`POST /broadcasts`

## Request

- Base URL: `https://sendhq.cc/api/v1`
- URL: `https://sendhq.cc/api/v1/broadcasts`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/sendhq/apis/sendhq-api/docs/broadcasts/post.ts> (a function with typed inputs; its response is checked against the schema)

Create a draft for one list: `from` on a verified domain, `subject`, optional `preview_text`, and content as `html` and/or `text`, `markdown`, a block document in `content`, or a published hosted `template` ({id or key, optional version_id}). Markdown and block content are rendered with the workspace design (newsletter settings). Raw content supports merge tags such as `{{first_name}}`, `{{fields.plan}}`, and fallbacks like `{{first_name | there}}`; HTML values are escaped. `audience` narrows who gets it: `segment_id` (only list members matching a segment), `limit` (at most this many people), and `order` (`signup`, or `engaged` for most engaged first). `tracking` turns open and click tracking on or off (both on by default). `web.enabled` publishes the issue on the list's newsletter site once it is sent. To send later, create the draft, then call POST /broadcasts/{id}/schedule; `scheduled_at` is not accepted here.
