Webhook is used to ask AfterShip to push back any updates to your system. This is used when the store wants to send out notifications by themselves or receive the latest delivery status / checkpoint. Unlike using API (Get tracking), using webhook is a more efficient way to get delivery updates as webhook asks AfterShip to push back instead of the store keep on asking AfterShip for any updates. Users can select when to ask AfterShip pushes back delivery updates when using webhook.
To setup webhook, go to " Settings > Triggers" and select "Webhook" after sign in, you can then input a URL where you want to receive the updates from AfterShip, and also select the triggers when to receive such updates.
