Amplitude

Amplitude is a powerful mobile analytics service. Send events to Amplitude via Apphud, analyze your users behavior and make necessary decisions.

How to Add Integration?

Step 1

• Integrate Apphud SDK.
• Integrate Amplitude SDK.
• Match User IDs between Apphud and Amplitude. If you set your custom User ID keep in mind that Amplitude requires user id to be minimum 5 characters.

Step 2

At Apphud go to "Integrations" section and add Amplitude:

Step 3

Enter Amplitude API Key at the "Amplitude production app API Key" field:

Step 4

You may have one more app created in Amplitude used for testing purposes not to mix test and live data. If you have such app you can paste it's Amplitude API Key into "Amplitude test app API key" field.

Step 5

You can enter your custom event names or disable some:

Step 6

Enable integration and Save:

Match User IDs

Here is an example of initialising both SDKs with User IDs matching.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    Apphud.start(apiKey: "YOUR_API_KEY")
    Apphud.setDelegate(self)
    
    Amplitude.instance()?.initializeApiKey("AMPLITUDE_API_KEY", userId: Apphud.userID())

    return true
}

func apphudDidChangeUserID(_ userID: String) {
    // Match again
    Amplitude.instance()?.setUserId(userID)
}

[Apphud startWithApiKey: @"API_KEY"];
[[Amplitude] instance] initializeApiKey:@"API_KEY" userId:[Apphud userID]];

Apphud.start(apiKey: "YOUR_API_KEY")
Amplitude.getInstance().initialize(this, "AMPLITUDE_API_KEY", Apphud.userID());

Future<void> _initAmplitude() async {
    final analytics = Amplitude.getInstance(instanceName: 'project');
    final userId = await Apphud.userID();
    await analytics.init('API_key', userId: userId);
  }

@override
  Future<void> apphudDidChangeUserID(String userId) async {
    printAsJson('ApphudListener.apphudDidChangeUserID', userId);

    final analytics = Amplitude.getInstance(instanceName: 'project');
    final userId = await Apphud.userID();
    await analytics.setUserId(userId);
  }
