Amplitude

Linkrunner integrates with Amplitude 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 Amplitude 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 Amplitude, 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.
Amplitude account	An Amplitude account with API access.
iOS or Android app	This integration supports iOS and Android apps.
Linkrunner SDK	You must have the Linkrunner SDK installed in your app.

Steps to setup

Create API Key in Amplitude and Configure in Linkrunner

First, you need to get your API key from your Amplitude dashboard.

In your Amplitude dashboard, navigate to Settings > Projects > API Keys
Copy your API Key
In Linkrunner, navigate to Integrations from the left-hand panel
Under Analytics, click Configure for Amplitude
Enter your API Key

Map User Identifiers in SDK

To properly link users between Linkrunner and Amplitude, you need to pass the correct identifier in the signup function.

Important: If you are using the identify function of the Amplitude SDK to set a user ID, pass the same user ID in the userData parameter of the Linkrunner signup function. If you are not using identify, pass the distinct_id or device_id instead.

Android (Kotlin)
iOS (Swift)
React Native
Flutter

import io.linkrunner.sdk.LinkRunner
import io.linkrunner.sdk.models.request.UserDataRequest

val userData = UserDataRequest(
    id = "123", // Your user ID (same as Amplitude identify)
    // ...other user fields
    amplitudeDeviceId = "AMPLITUDE_DEVICE_ID", // Required if not using identify
)

LinkRunner.getInstance().signup(userData = userData)

import Linkrunner

let userData = UserData(
    id: "123", // Your user ID (same as Amplitude identify)
    // ...other user fields
    amplitudeDeviceId: "AMPLITUDE_DEVICE_ID" // Required if not using identify
)

try await LinkrunnerSDK.shared.signup(userData: userData)

import linkrunner from "rn-linkrunner";

await linkrunner.signup({
    user_data: {
        id: "123", // Your user ID (same as Amplitude identify)
        // ...other user fields
        amplitude_device_id: "AMPLITUDE_DEVICE_ID", // Required if not using identify
    },
    data: {},
});

import 'package:linkrunner/main.dart';

await LinkRunner().signup(
  userData: LRUserData(
    id: '123', // Your user ID (same as Amplitude identify)
    // ...other user fields
    amplitudeDeviceId: 'AMPLITUDE_DEVICE_ID', // Required if not using identify
  ),
  data: {},
);

You can get the amplitudeDeviceId from the Amplitude SDK in your app.

Sync with Amplitude (Optional)

Use the Sync feature in the following scenarios:

First time after adding your Amplitude API Key
If you see discrepancies in attribution data on Amplitude profiles

To sync, click the Sync with Amplitude button in the Linkrunner integration settings. This process may take a while depending on the number of users.

Viewing Attribution Data

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

Navigate to a user profile in the Amplitude dashboard
Look for the user properties section
You’ll see lr_campaign and lr_ad_network attributes with the corresponding values

This data can be used to:

Create cohorts based on acquisition source
Personalize experiences based on campaign origin
Analyze user behavior by acquisition channel
