# List Result Sets

You can List all of the Result Sets for a Collection by making a  `HTTP GET` request to the  `/Collections/COLLECTION_ID/results` endpoint (where  `COLLECTION_ID` is the  `id` of the Collection to get Result Sets for). Countdown API retains Result Sets for 14 days so you should download your Result Set data within this 14 day window.

### Example

<font color="#52c41a">`GET`</font>  `/collections/COLLECTION_ID/results`

In the example below we List all of the Result Sets for the Collection with  `id=123456` :

HTTP

```HTTP
https://api.countdownapi.com/collections/123456/results?api_key=demo
```

```curl
$ curl "https://api.countdownapi.com/collections/123456/results?api_key=demo"
```

```nodejs
const axios = require('axios');
const params = {
  api_key: 'demo'
}

axios.get('https://api.countdownapi.com/collections/123456/results', { params })
  .then(response => {
    const apiResponse = response.data;

  }).catch(error => {
    console.log(error);
  });
```

```python
import requests

params = {
  'api_key': 'demo'
}

api_result = requests.get('https://api.countdownapi.com/collections/123456/results', params)

api_response = api_result.json()
```

```php
<?php
      
$queryString = http_build_query([
  'api_key' => 'demo',
]);

$ch = curl_init(sprintf('%s?%s', 'https://api.countdownapi.com/collections/123456/results', $queryString));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 180);

$json = curl_exec($ch);
curl_close($ch);

$api_result = json_decode($json, true);

print_r($api_result);

?>

Countdown API responds with the following JSON showing all the Results Sets for the Collection. Note the  `results` array contains a list of all of the Result Sets. The  `id` property of a Result Set should be used with the [Get Result Set](https://docs.trajectdata.com/countdownapi/collections-api/results/get) endpoint to retrieve the actual results within the Result Set.

**Note**  the  `results`  array is sorted by the most recently run Result Set first.
