# Webhooks

**Webhook URL** is the endpoint on your side that receives a GET or POST request from TADS when a user triggers an event. Optionally, you can add it when [creating a widget.](/docs/getting-started/publishers/create-widget.md)

The type of event that triggers the webhook is automatically defined by the widget format:

* For **TGB format**, the webhook is triggered **on ad click**.
* For **Fullscreen format**, the webhook is triggered **on ad view**.

Each POST request includes json object with the following data:

* **`telegram_id`** (string) – user Telegram  ID
* **`widget_id`** (string) – ID of the widget where the ad was shown/clicked

{% hint style="info" %}
Please make sure your webhook handler expects **exactly the same parameter names and types** as listed above.
{% endhint %}
