# Resend: Topics Create

> Create a new topic. Resend Topics Create reference includes SDK V2 and CLI requests, input constraints, response fields, and Deepline cost.

Create a new topic.

> [!NOTE]
>
> Tool ID: `resend_topics_create`

## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'resend_topics_create',
  {
    "name": "Example",
    "default_subscription": "opt_in"
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline run resend_topics_create --input '{
  "name": "Example",
  "default_subscription": "opt_in"
}'
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "data": {
    "id": "id_123",
    "object": "example"
  }
}
```

Use `deepline describe resend_topics_create --json` for the latest machine-readable contract.
