Ticket status update delay

Ticket status update delay


I've initiated the process by generating several tickets within the Zoho Desk. Subsequently, I modified the status of some of these tickets from "
OPEN" to "CLOSE." Afterward, I attempted to retrieve these modified tickets through an API call. Although the updated ticket statuses were correctly reflected in Zoho Desk, it seems that when I retrieve these tickets via an API call, their statuses still appear as "OPEN" despite the previous change from "OPEN" to "CLOSE." This API retrieval process takes more than 30 seconds to reflect the updated ticket status. Also if I filter tickets based on status, the same tickets show for OPEN and CLOSE filter data. 

Why its's taking more time to update?
