# Introduction of TrackingMore API

### Introduction of TrackingMore API

Trackingmore API is a shipment tracking API that returns tracking info of our supported couriers. You can insert tracking results directly at your application or store, and notify users of delivery updates using webhooks. 

The Trackingmore API is implemented as JSON over HTTP using all four verbs (GET/POST/PUT/DELETE). Each resource, like Tracking, Courier, has its own URL and is manipulated in isolation. In other words, we've tried to make the API follow the REST principles as much as possible.
