# Example responses (/docs/guides/example-responses)

Add `response` code blocks to a request's description in Yaak. Put an HTTP status code after it to show several responses (success, errors, ...):

````md title="Request description in Yaak"
Retrieve a single product by its id.

```response:200
{
  "id": "prod_123",
  "name": "Running shoes"
}
```

```response:404
{
  "error": "not_found"
}
```
````

- **Shown as tabs.** Response blocks are removed from the description and shown as tabbed, syntax-highlighted examples labeled by status (`200 OK`, `404 Not Found`). They're also included in the Markdown and `llms.txt` output.
- **No status code.** A plain `response` block is labeled "Response".
- **Language.** JSON, XML and HTML are detected automatically. To set the language yourself, add it after the status, e.g. `response:200 yaml`.
- **Empty bodies.** An empty block, such as `response:204`, shows "No response body".
