# Webhook integration synchronization frequency

The following restrictions in detail will help you better understand the operational concepts of Webhook integration.

**Sync every 9 minutes:** Our server checks for new messages every 3 minutes from your WhatsApp Web and uploads them to your endpoint every 6 minutes. In summary, there might be a 9-minute delay between when you receive a new message and when it syncs to your endpoints.

|| Please note that during the initial upload of all messages, the large volume may cause the waiting time to exceed 9 minutes.
