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](/docs/api-reference/broadcasts/duplicate-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.

```nodejs
import { Resend } from 'resend';

const resend = new Resend('re_xxxxxxxxx');

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

```php
$resend = Resend::client('re_xxxxxxxxx');

$resend->broadcasts->duplicate('559ac32e-9ef5-46fb-82a1-b76b840c0f7b');
```

```python
import resend

resend.api_key = "re_xxxxxxxxx"

resend.Broadcasts.duplicate(id="559ac32e-9ef5-46fb-82a1-b76b840c0f7b")
```

```ruby
require "resend"

Resend.api_key = "re_xxxxxxxxx"

Resend::Broadcasts.duplicate("559ac32e-9ef5-46fb-82a1-b76b840c0f7b")
```

```go
import "github.com/resend/resend-go/v4"

client := resend.NewClient("re_xxxxxxxxx")

duplicated, _ := client.Broadcasts.Duplicate("559ac32e-9ef5-46fb-82a1-b76b840c0f7b")
```

```rust
use resend_rs::{Resend, Result};

#[tokio::main]
async fn main() -> Result<()> {
  let resend = Resend::new("re_xxxxxxxxx");

  let _duplicated = resend
    .broadcasts
    .duplicate("559ac32e-9ef5-46fb-82a1-b76b840c0f7b")
    .await?;

  Ok(())
}
```

```java
Resend resend = new Resend("re_xxxxxxxxx");

DuplicateBroadcastResponseSuccess data = resend.broadcasts().duplicate("559ac32e-9ef5-46fb-82a1-b76b840c0f7b");
```

```dotnet
using Resend;

IResend resend = ResendClient.Create( "re_xxxxxxxxx" );

var duplicated = await resend.BroadcastDuplicateAsync( new Guid( "559ac32e-9ef5-46fb-82a1-b76b840c0f7b" ) );
```

```curl
curl -X POST 'https://api.resend.com/broadcasts/559ac32e-9ef5-46fb-82a1-b76b840c0f7b/duplicate' \
     -H 'Authorization: Bearer re_xxxxxxxxx'
```

```cli
resend broadcasts duplicate 559ac32e-9ef5-46fb-82a1-b76b840c0f7b
```
</CodeTabs>

The endpoint returns the ID of the new Broadcast:

```json
{
  "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.
