Tracks a conversion event. Logs an error message if the specified event key does not match any existing events.
SDK v3.0 and higher
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.
The attributes passed to Track are only used for results segmentation.
This table lists the required and optional parameters for the Java SDK.
|string||The key of the event to be tracked. This key must match the event key provided when the event was created in the Optimizely app.|
|string||The ID of the user associated with the event being tracked.|
Important: This ID must match the user ID provided to Activate or Is Feature Enabled.
|map||A map of custom key-value string pairs specifying attributes for the user that are used for results segmentation. Non-string values are only supported in the 3.0 SDK and above.|
|map||A map of key-value pairs specifying tag names and their corresponding tag values for this particular event occurrence. Values can be strings, numbers, or booleans.|
These can be used to track numeric metrics, allowing you to track actions beyond conversions, for example: revenue, load time, or total value. See details on reserved tag keys.
This method sends conversion data to Optimizely. It does not provide return values.
Map<String, Object> attributes = new HashMap<>(); attributes.put("device", "iPhone"); attributes.put("lifetime", 24738388); attributes.put("is_logged_in", true); Map<String, Object> tags = new HashMap<>(); attributes.put("category", "shoes"); attributes.put("count", 2); optimizelyClient.track("my_purchase_event_key", "user_123", attributes, tags);
|Java||UnknownEventTypeException||The event type is malformed or isn't in the datafile.|
The table lists other other Optimizely functionality that may be triggered by using this method.
|Conversions||Calling this method records a conversion and attributes it to the variations that the user has seen.|
Full Stack 3.x supports retroactive metrics calculation. You can create metrics on this conversion event and add metrics to experiments even after the conversion has been tracked.

- This method will not track events when the specified event key is invalid.
- Changing the traffic allocation of running experiments affects how conversions are recorded and variations are attributed to users.
