You can use Vercel Serverless Functions to receive webhooks from third-party services like Stripe. Certain providers require access to the raw body inside the function to validate the signature from the request.

## Accessing the raw body from the request

```javascript
export async function POST(request: Request) {
  const rawBody = await request.text()
  return Response.json({ rawBody })
}
```

## Testing your function locally

You can verify your function can accept and parse raw bodies locally:

1. Start your local development server with `vercel dev` (or `next dev`).
   
2. In another terminal window, run the `cURL` command below.
   

```bash
curl -X POST -H "Content-Type: text/plain" --data "This is raw data" http://localhost:3000/api/test
```

You should see a response like `{"rawBody": "This is raw data"}`.
