Duplicate Broadcast API

Duplicate an existing broadcast directly from the API.

Gabriel Miranda

Most new Broadcasts start from one you've already sent. Previously, duplicating a Broadcast was only possible from the Dashboard.

Today we're releasing a new API endpoint to duplicate a broadcast.

How it works

Pass the ID of an existing Broadcast and the API creates a copy:

  • The copy is named after the original with a (copy) suffix, truncated to 70 characters.
  • The segment, topic, sender, subject, reply-to, preview text, and content are copied.
  • The copy starts as a draft. Nothing is sent until you review and send it.

Any Broadcast can be duplicated, including ones that have already been sent.

Duplicating a Broadcast

To duplicate a Broadcast, use the Broadcast's ID with the duplicate endpoint.

import { Resend } from 'resend';


const resend = new Resend('re_xxxxxxxxx');


const { data, error } = await resend.broadcasts.duplicate(
  '559ac32e-9ef5-46fb-82a1-b76b840c0f7b',
);

The endpoint returns the ID of the new Broadcast:

{
  "object": "broadcast",
  "id": "1f85ae38-f5b9-4c1f-8766-667a53970fea"
}

The duplicate Broadcast API is part of a larger move to bring the full functionality of the dashboard into the API, CLI, and MCP, so you can build how you want.
