Set up Epsilon

Epsilon is an ad network integrated with Adjust. Our integration lets Epsilon receive attribution and in-app event data through automated callbacks.

In this article, learn how to set up measurement with Epsilon for your app. This includes activating the integration, creating a campaign link, and choosing what data Adjust can share with Epsilon.

Before you begin


iOS / Android / Windows / Unity / React Native / Flutter / Adobe Air / Cordova / Marmalade / Xamarin / Cocos2d-x / Titanium / Corona


Company ID and Company Magic

  • For help finding your credentials, contact your Epsilon representative.

Select Epsilon and your app in Campaign Lab

  1. Under Campaign Lab, select Partners.
  2. Select New partner > Epsilon. Select Next to move to the next screen.
  3. In the App selection screen, choose the app for which you want to create the link, and enable the integration to share data with Epsilon.
  4. Select Next.

Enable data sharing

Enable data sharing to activate the integration with Epsilon. To enable data sharing:

  1. Enter your Company ID and Company Magic.

Once you enable data sharing with Epsilon, Adjust automatically sends Epsilon the following data, by default:

  • install
  • session
  • reinstall
  • event

Set your data sharing options

If you’re working with a multi-platform app with data sharing enabled for multiple platforms, you can:

  1. Separate data sharing options at the platform-level by selecting Use platform-specific settings.
  2. Set the same data sharing settings for multiple platforms by selecting Use global settings.

Now, under What will be shared by default?, review the activities that Adjust shares with Epsilon by default.

  • install
  • session
  • reinstall
  • event

Send additional data

Choose the amount and type of data that you want to share with Epsilon through callbacks. Epsilon may use this information to optimize performance.

  1. Under What sources of data do you want to share?, choose the attribution source of the data you are sharing with Epsilon:
  • Data from all attribution sources
  • Only data attributed to Epsilon

In-app revenue (from in-app purchases)

Sharing in-app revenue lets Epsilon receive revenue amounts along with your revenue event data. You need to map events that generate revenue to share this data.

Uninstalls or reinstalls

Sharing uninstalls or reinstalls lets Epsilon receive your app’s uninstall and/or reinstall data measured by Adjust.


For iOS apps, you might expect a low record of uninstalls and/or reinstalls. For more information, visit Uninstall and reinstall measurement.


Adjust does not automatically send session callbacks due to the high volume of sessions. Sharing sessions means Epsilon will receive your app’s session activity.

Map parameters

You usually need to map parameters to share custom data with Epsilon.

Map events

Map events that you want to share to the values that Epsilon can receive. Data for unmapped events is not shared with Epsilon.

Under Map events, follow these steps to choose the in-app events you want to directly send to Epsilon.

  1. Select Map event.
  2. In the Adjust event list, choose the Adjust event that you want to share with Epsilon.
  3. In the Partner event list, choose or enter a custom event name that you want to map the Adjust event to. You might have to map an event to several values.
  4. Select Apply.

Now Epsilon will receive in-app event data for each of your linked events.

Map parameters

Partner parameters (available in Adjust SDK version 4.0+) let Adjust collect custom data points from your app and send them to Epsilon. This lets Epsilon receive custom event details for each of your linked events.

Before adding new partner parameters to the Adjust SDK, make sure no pre-existing partner parameters already fit your requirements.

To share partner parameters to Epsilon, follow these steps.

  1. Set up partner parameters within the Adjust SDK: iOS, Android
  2. Check the Parameters data sharing checkbox.
  3. Map your events.

If you set up partner parameters within the Adjust SDK without setting up parameter sharing in the dashboard, Adjust forwards the parameters as named in the Adjust SDK.

Configure your link and settings

You have the option to set your:

Create your link and share it with Epsilon

In the Setup review screen, you can review your choices. You can also go back and make changes to:

  • Your selected app
  • Data sharing options
  • Link structure parameters
  • User destinations
  • Attribution settings

Select Create link to create your click URL, impression URL, QR code and link token. Creating a link also enables data sharing and the integration with Epsilon.

Once you’ve created your link, share it with Epsilon for placement in campaigns.

Partner specific setup instructions

Epsilon allows you to send a set of predefined parameters. If you attach any of these parameters to an event or session in your adjust SDK, these will be forwarded to Epsilon . You can find out more about attaching partner parameters in the SDK readme specific to the SDK or SDKs you are working with. Below is a list of the defined parameters that Epsilon accepts:
