# Throttling

To maintain an high quality of service Gsped applies some throttling rules for the API calls.

In the following table are reported the limits not to be overcome:

{% hint style="info" %}
**the limits refer to 5 minute intervals**
{% endhint %}

| Type of Call          | Call limit |
| --------------------- | :--------: |
| Shipment POST         |     300    |
| Shipment Confirm POST |     300    |
| Other calls POST      |     450    |
| DELETE calls          |     600    |
| GET Calls             |    1200    |

The overcoming of these limits leads to a 403-FORBIDDEN

For the tracking endpoint calls we suggest not to call more than once per hour for the single shipment; on average our systems query the systems of the couriers every 60 minutes.

It is possible to ask for the activation of webhooks in your systems to avoid pollings on Gsped.
