# Setting Up S2S Tracking

_Chartboost's S2S tracking lets you leverage install attribution from third-party platforms to create CPI campaigns on the Chartboost network._

Apps may advertise using SDK attribution or server-to-server attribution. If you plan on spending more than $1,000 per day, you may use server-to-server attribution through a third party.



## Add click callbacks to your app

1.  Navigate to the  [Callbacks panel](https://platform.chartboost.com/advertising/callbacks)  of your platform and click  **Add New Callback**.
2.  Create a click callback using a third-party template from the  **Template**  dropdown. Be sure to select the template that applies to your app's OS platform (iOS or Android).
3.  You will be prompted to enter additional information the third party requires, such as a bundle id.
4.  After filling in the callback template, attach the callback to the  **click events**  of the app you want to track via the third party. Select the app, go to  **APP SETTINGS > Basic Settings > Advanced Settings**, and select your click callback from the dropdown.
5.  Click  **Save**.



## Add completed view callbacks to enable view-through attribution (VTA)

**View-through attribution (VTA)**  allows you to register installs seen when a user installs your app within a short timeframe after watching a video ad, even if the user did not click on the ad.  [Learn more](/en/faq/advertising/#what-is-view-through-attribution-vta)

1.  Go to your Chartboost platform's  [callbacks panel](https://platform.chartboost.com/advertising/callbacks)  and click  **Add New Callback**.
2.  Name your callback and give it a description.
3.  From the  **Template**  dropdown, select the Completed View template for your partner (e.g. "Tune iOS Completed View").
4.  You might be prompted to add your  [bundle ID](/en/faq/sdk-integration/)  or other information.
5.  Find the app(s) for this callback in the list below your callback details. Check the box in the  **View**  column.
6.  Switch your callback from  **OFF**  to  **ON**  and then click  **Save**.



## Configure your third-party platform to send attribution & bootup data

Choose your third-party service for more instructions:

-   [Adjust](/en/advertising/s2stracking/adjust/)
-   [AppsFlyer](/en/advertising/s2stracking/appsflyer/)
-   [Kochava](/en/advertising/s2stracking/kochava/)
-   [Singular](/en/advertising/s2stracking/singular/)
-   [Tenjin](/en/advertising/s2stracking/tenjin/)

To ensure the best targeting and performance of your apps, bootup/install notifications  **must always be called within the first few seconds of your app launching,**  regardless of any other actions or user interactions within your app.

### Locating your user ID and user signature

1. Log in to your [Chartboost platform](https://platform.chartboost.com/)
2. Navigate to **Mediation**. You will be redirected to the Helium Dashboard (<https://helium.chartboost.com/>).
3. From the left navigation, go to **Resources > API Explorer**.
4. Your **user ID** and **user signature** is listed under **Authentication**

## Ask Chartboost to turn on S2S tracking

-   Reach out to your account manager to enable S2S for your account.
-   If you are new to Chartboost, we require a minimum deposit of $5,000 into your account to enable S2S features. Please  [add more funds](/en/advertising/finances/)  to your account and then  [contact us.](/en/support/contact-us/)  
    

If your app was SDK-integrated and being promoted by a Chartboost advertising campaign before you requested S2S tracking, you may be billed for SDK-driven installs up to 21 days after conversion is complete. After conversion, the install attribution window will be according to the third party, with a minimum of 7 days.
