Track

Tracks a conversion event. Logs an error message if the specified event key does not match any existing events.

Version

SDK v1.0

Description

Use this method to track events across multiple experiments. You should only send one tracking event per conversion, even if many feature tests or A/B tests are measuring it.

📘

Note

Events are counted in an experiment when an impression was sent as a result of the Activate or Is Feature Enabled method being called.

The attributes passed to Track are only used for results segmentation.

The Track function can be used to track events across multiple experiments. It will be counted for each experiment only if Is Feature Enabled or Activate has previously been called for the current user.

As long as the event key is valid (the key appears in the datafile) Optimizely will track events. Use attributes to track events for segmentation purposes.

🚧

Important

The Results page only shows events that are tracked after Is Feature Enabled or Activate has been called. If you do not see results on the Results page, make sure that you are evaluating the feature flag before tracking conversion events.

Track events across platforms

For offline event tracking and other advanced use cases, you can also use the Events API.

You can use any of our SDKs to track events, so you can run experiments that span multiple applications, services, or devices. All of our SDKs have the same audience evaluation and targeting behavior, so you'll see the same output from feature experiment evaluation and tracking as long as you are using the same datafile and user IDs.

For example, if you're running feature experiments on your server, you can evaluate them with our Go, Python, Java, Ruby, C#, Node, or PHP SDKs, but track user actions client-side using our JavaScript, Objective-C or Android SDKs.

If you plan to use multiple SDKs for the same project, make sure that all SDKs share the same datafile and user IDs.

Parameters

This table lists the required and optional parameters for the Go SDK.

Returns

This method sends conversion data to Optimizely. It does not provide return values.

Example

attributes := map[string]interface{}{
        "DEVICE": "iPhone",
        "hey":    2,
}

user := entities.UserContext{
        ID:         "userId",
        Attributes: attributes,
}

err := optlyClient.Track("add_to_cart", user)
