# Send a changelog broadcast

> Broadcast an existing changelog to subscribers via email and/or Slack. Pass `email: true` to send to subscribed contacts (requires the email integration enabled) and/or `slack: true` to post to the configured Slack channels (requires Slack connect). At least one channel is required. This endpoint never toggles `published` - use PATCH /changelogs/{id} for that. Requires the Pro plan or higher and the changelogs:write scope.
