Get document list by their request_status for example "completed" in Zoho api PHP?

I am trying to connect with Zoho CRM using php. I followed this document https://www.zoho.com/sign/api/#get-documents-list for fetching list of sign documents.

It is taking long time on processing and sending response. I am trying to filter my request so that it will return only those documents which has request_status "completed".

Also, is there any way to fetch Intern docs using same api?

My website is in wordpress and i am using this code:

function zoho_doc_call($page, $docs_array) {  $token = get_zoho_token();  $params = str_replace("}","%7D", str_replace("{","%7B","{%22page_context%22:{%22row_count%22:50,%22start_index%22:".$page."}}"));  $url = "https://sign.zoho.com/api/v1/requests?data=".$params;  $args = array('headers' => array( "Authorization" => "Bearer ".$token),  );  $response = wp_remote_get( $url, $args );  if ( is_array( $response ) ) {    $response = json_decode(wp_remote_retrieve_body( $response ), true);    //echo "<pre>"; print_r($response);die;    $new_array = array_merge($docs_array, $response['requests']);    }    if ($response['page_context']['has_more_rows']) return zoho_doc_call($page+100, $new_array);  return $new_array;}

I am new to this api. Can anyone please help me to fix long waiting time issue?

Thanks!
