Cloudflare Clear Cache For One URL, Convert Curl Command to Drupal::httpClient() Or php
https://api.cloudflare.com/#zone-purge-files-by-url
I found the solution, so this command:
curl -X POST &quot;https://api.cloudflare.com/client/v4/zones/abcdefghijklabcdefghijkl/purge_cache&quot; \
     -H &quot;Authorization: Bearer abcdefghijklabcdefghijkl&quot; \
     -H &quot;Content-Type: application/json&quot; \
     --data '{&quot;files&quot;: [&quot;https://example.com&quot;, {&quot;url&quot;: &quot;https://example.com/url&quot;}]}'

It will be in Drupal like:
      $client = \Drupal::httpClient();
      $options = [
        'headers' =&gt; [
          'Authorization' =&gt; 'Bearer abcdefghijklabcdefghijkl',
        ],
        'json' =&gt; [
          'files' =&gt; ['https://example.com/url']
        ],
      ];
      $response = $client-&gt;request('POST', $url, $options);
      $data = $response-&gt;getBody()-&gt;getContents();
      $data = json_decode($data, TRUE);
      if ($data['success']  == TRUE){
        return TRUE;
      }
