# Netcore

> Connect Linkrunner with Netcore to import attribution data and understand your user acquisition campaigns

Linkrunner integrates with Netcore to automatically send attribution data, helping you understand which campaigns are driving user acquisition and engagement.

## How it works

Every time a user is attributed by Linkrunner, we automatically send a request to Netcore to update the corresponding user's profile with custom properties:

* `lr_campaign` - The campaign identifier
* `lr_ad_network` - The ad network source

### Example

* User ID `24` came from campaign link: `https://app.linkrunner.io/?c=AXb1c2`
* In Netcore, for user profile with ID `24`, you'll see `lr_campaign` set to `AXb1c2` and `lr_ad_network` set to an ad network source

## Prerequisites

| Requirement        | Description                                                              |
| ------------------ | ------------------------------------------------------------------------ |
| Linkrunner account | A Linkrunner account is required to take advantage of this integration.  |
| Netcore account    | A Netcore account with API access.                                       |
| iOS or Android app | This integration supports iOS and Android apps.                          |
| Linkrunner SDK     | You must have the [Linkrunner SDK](/introduction) installed in your app. |

## Steps to setup

<Steps>
  <Step title="Get Credentials from Netcore and Configure in Linkrunner">
    First, you need to get your credentials from Netcore.

    1. Refer to [Netcore's Getting Started guide](https://developer.netcorecloud.com/reference/getting-started) to get the API Key and API Endpoint

    2. Copy the following credentials:
       * **API Endpoint** (e.g., `https://netcoreapi-main-prod-us.netcorein.com`)
       * **API Key**

    3. In Linkrunner, navigate to **Integrations** from the left-hand panel

    4. Under **Analytics**, click **Configure** for Netcore

    5. Enter your **API Endpoint** and **API Key**
  </Step>

  <Step title="Map User Identifiers in SDK">
    To properly link users between Linkrunner and Netcore, you need to pass the correct identifier in the `signup` function.

    <Info>
      **Important:** If you are using the `setUserIdentity` function of the Netcore SDK, pass the same user ID in the `userData` parameter of the Linkrunner `signup` function. If you are not using `setUserIdentity`, pass the `netcore_device_guid` instead.

        val userData = UserDataRequest(
            id = "123", // Your user ID (same as Netcore setUserIdentity)
            // ...other user fields

          data: {},
        );
        ```

    <Tip>
      You can get the `netcoreDeviceGuid` from the Netcore SDK in your app.
    </Tip>
  </Step>

  <Step title="Sync with Netcore (Optional)">
    Use the **Sync** feature in the following scenarios:

    * First time after adding your Netcore credentials
    * If you see discrepancies in attribution data on Netcore profiles

    To sync, click the **Sync with Netcore** button in the Linkrunner integration settings. This process may take a while depending on the number of users.
  </Step>
</Steps>

## Viewing Attribution Data

After the integration is complete, you can view the attribution data in Netcore:

1. Navigate to a user profile in the Netcore dashboard
2. Look for the user attributes section
3. You'll see `lr_campaign` and `lr_ad_network` attributes with the corresponding values

This data can be used to:

* Create segments based on acquisition source
* Personalize messaging based on campaign origin
* Analyze user behavior by acquisition channel
