The problem is like in topic ( https://help.zoho.com/portal/community/topic/non-any-results-after-getdata-php-sdk).

My code:

$ZohoCFG = parse_ini_file(__DIR__.'/resources/zoho_sdk.properties');
/*

    [client_secret] => 50eeXXX

    [apiBaseUrl] => https://www.zohoapis.eu

 */
ZCRMRestClient::initialize($ZohoCFG);
$ContactsModule = ZCRMModule::getInstance('Contacts');
$Contacts = $ContactsModule->getRecords();
var_dump($Contacts);
/*object(zcrmsdk\crm\api\response\BulkAPIResponse)#10 (12) {

*/

$records = $Contacts->getData();
var_dump($records);
/*
array(0) {
}
*/

What I'm doing wrong?

Best regards
