Polling means your system asks for a status update at set intervals, say every few minutes, whether or not anything changed. Webhooks flip that around: SendFast pushes an update to you the moment a shipment status changes. Webhooks are faster and lighter on your servers. Polling is a fallback for when a carrier doesn't push events. ClickPost uses both, so you get updates either way.

The idea is to trigger a message each time a shipment hits a milestone like shipped, out for delivery, or delivered. To do that you need tracking events coming in, logic that decides which event sends what, and a connection to your SMS, WhatsApp, or email provider. That notification layer usually sits outside the carrier's API itself. In practice it's handled by a post-purchase platform like ClickPost, which reads SendFast status updates and fires the alerts on set rules.

Most courier APIs offer a similar core set, and SendFast's covers the usual shipping lifecycle: order creation with label generation, shipment tracking, cancellation, delivery estimates, failed-delivery handling, and return pickups. The exact fields and endpoints vary by carrier. When SendFast is accessed through ClickPost, these functions are exposed through one standardized API, so you don't have to learn SendFast's specific format to use them.

A few common reasons could be: the tracking number was entered wrong, the parcel was only just booked and SendFast hasn't scanned it yet, or the carrier's system is running behind. Status often sits quiet during transit between hubs and then jumps several steps at once. Give it a few hours. If it hasn't moved in a day or two, contact your seller or SendFast with the tracking number.

SendFast covers more than 15,000 pin codes across India. Its real strength is reach into Tier II and Tier III towns, where a lot of national carriers thin out, with a particular focus on South India. It handles both intracity and intercity movement, so it works for local hyperlocal drops as well as parcels traveling between cities.

Yes. Same-day and hyperlocal delivery are core to what SendFast does. It runs its own fleet of bikers and vans for quick city drops, which suits restaurants, grocery, pharmacy, and retail orders that can't wait. For longer routes it moves parcels intercity, so next-day delivery depends on the distance and the specific lane you're shipping on.

It's a ready-built connection between SendFast and ClickPost's platform. You connect to ClickPost once and get SendFast order creation, tracking, cancellation, delivery estimates, NDR handling, and returns through that single link. Building and maintaining the SendFast integration yourself is the alternative, which takes far more developer effort. The same ClickPost connection also runs your other carriers, so everything stays in one place.

After the integration is live, ClickPost pulls SendFast status updates in real time using webhooks and polling. Those updates land on your dashboard, feed your branded tracking page, and trigger customer notifications, all from the same data. So your team, your tracking page, and your customer are always looking at the same status without anyone refreshing the carrier site.
