Create Broadcast

Creates a new broadcast bound to an existing source. Starts in NOT_STARTED. Endpoint: POST /2/users/:user_id/broadcasts

The source must already be actively receiving an RTMP feed (is_stream_active: true), or this endpoint returns a 404. See the broadcast lifecycle overview.

Request body

{
  "source_id": "6ep48v6ar5q4",
  "region": "eu-central-1",
  "is_low_latency": true
}

Field	Type	Required	Description
`source_id`	string	Yes	ID of an existing source owned by this user.
`region`	string	Yes	Must match the source’s region.
`is_low_latency`	boolean	No	Requests low-latency mode (lower delay for interactive/chatty broadcasts, trading some quality/stability). If omitted, defaults to `false` (standard latency); we recommend setting it explicitly. The `is_high_latency` field in the response is informational only and does not reflect this value.

Example request

curl -X POST "https://api.x.com/2/users/172483972/broadcasts" \
  -H "Authorization: Bearer $USER_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"source_id":"6ep48v6ar5q4","region":"eu-central-1","is_low_latency":true}'

Key fields returned at creation

media_key / media_id: Required later for chat access and some playback.
video_access: Playback URLs (HLS variants). lhls* and replay_url may appear later or for certain modes.
share_url: Public viewer link (https://x.com/i/broadcasts/{id}).
state: Always starts "NOT_STARTED".
is_high_latency: Informational only; it does not reflect the is_low_latency value you sent.
twitter_user_id vs user_id vs owner_id: twitter_user_id is your numeric X user id (returned as a string) — use this for the :user_id path parameter in every endpoint. user_id (e.g. "1DYEXPNqZwqEg") is a separate alphanumeric livestream-platform id; do not use it in paths. Note also that the Source object’s owner_id is delivered as a JSON number and will lose precision for real (19-digit) user IDs — never rely on it; use twitter_user_id or your authenticated id instead.

After creation, start pushing your RTMP feed to the source’s rtmps_url + rtmp_stream_key if you haven’t already, then publish.
