CLIO возвращает только номер дела по номеру дисплея

Если проблема заключается в том, что вы не хотите делать x-bulk здесь, это код, который будет извлекать всю информацию, вы можете либо изменить код, чтобы найти элемент в данных, возвращаемых для каждой страницы, либо найти в конечном массиве.

    function performListRequestAllMatters()
{
$header = 'Authorization: bearer ' . $this->token;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->base . $this->API_version . 'matters' . '?fields=id,display_number');
curl_setopt($ch, CURLOPT_HTTPHEADER, array($header));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch);

if (!$response) {
die('Error: "' . curl_error($ch) . '" - Code: ' . curl_errno($ch));
} elseif (200 != curl_getinfo($ch, CURLINFO_HTTP_CODE)) {
echo "Bad Response Code!";
echo "\n";
echo "Response HTTP Status Code : " . curl_getinfo($ch, CURLINFO_HTTP_CODE);
echo "\n";
echo "Response HTTP Body : " . $response;
} else {

$json = json_decode($response, true);
$list = $json['data'];

while (isset($json['meta']['paging']['next'])) {
// process a new request until all pages have been retrieved
curl_setopt($ch, CURLOPT_URL, $json['meta']['paging']['next']);

$response = curl_exec($ch);
$json = json_decode($response, true);
$newList = $json['data'];

$list = array_merge($list, $newList);
}

}
curl_close($ch);

return $list;
}

если у вас более 10000 записей, вы должны использовать большую часть.
эта функция прекрасно работает для получения всех записей.
Тогда вы сможете найти то, что вам когда-либо понадобится
