Sorry, it was the issue in my argument, the correct format is:

$client = new GuzzleHttp\Client([
        'base_uri' => 'https://api.gndf.io',
      ]);

      $data = [
        'created' => 2
      ];

      $response = $client->post('/api/v1/tables/3453e53wsttwt/decisions', [
        'auth' => ['45grt3tetegter', 'dfg34tedrgtdgdfgdfgdfg'],
        'headers' => [
          'Content-Type' => 'application/json',
          'X-Application' => '4tergdrfsfwrfesf3453rfg'
        ],
        //'debug' => TRUE,
        'body' => json_encode($data)
      ]);

      $body = $response->getBody()->getContents();
      dd($body);
