# Server-to-Server Tracking

In this guide, we will explore how to set up the Attributed Action Postback for advertiser tracking. This process ensures that each time a user completes a designated action, a request is made to the API for real-time tracking. We will cover the necessity of making these requests promptly and individually rather than in bulk. Additionally, we will provide details on the request URL and the required `GET` method to ensure accurate tracking of user interactions.

## Setting Up the Attributed Action Postback

Advertiser tracking installs must make a request to the API every time a user completes the required action.

Requests must be made in realtime and cannot be made in bulk.

### Request URL

The URL you should request using the `GET` method is

`service.fyber.com/actions/v2`

### Parameters to Submit with the Request

Append the following parameters on every request.

{% hint style="info" %}

* Take a note of your DT `AppID`. It is required for the Server-to-Server action postback.
* To achieve maximum reach of your campaign, use an https tracking URL.
  {% endhint %}
