Taplytics Java SDK

Taplytics Java SDK is an sdk to enable features such as Experimentation and Feature Flag functionality.

Initialization

First, import the taplytics-java-sdk JAR into your project.

Then, import the API client into the desired class:

import com.taplytics.sdk.APIController;

API client can be then initialized as following:

APIController taplytics = new APIController('API_KEY');

Identification

All method calls to Taplytics require a user id. This is to ensure that the user will always receive the correct experiments and variations across all platforms.

Methods

All methods can be handled with a callback, or used as a CompletableFuture, i.e.

try {
  JSONObject config = taplytics.getConfig(...).get();
  // use config
} catch (ExecutionException e) {
  // error e
}

If a callback is provided, the function will not return a promise.

getBucketing

Returns a key/value pairing of all experiments that the user has been segmented into, as well as the variation the users are assigned.

Parameters

Parameter	Tags	Description
userId	Required	ID for current user
attributes	Optional	Provide all relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.getBucketing(userId, attributes)
	.handle((bucketing, err) -> {
		// your code here
}).join();

getVariables

All variables and their values for the given user

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
attributes	Optional	All relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.getVariables(userId, attributes)
	.handle((variables, err) -> {
		// your code here
}).join();

getVariationForExperiment

For a given experiment, determine whether or not a user is in the experiment, and in which variation

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
experimentName	Required	Name of an Experiment
attributes	Optional	All relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
String experimentName = "experimentName";
JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.getVariationForExperiment(userId, experimentName, attributes)
	.handle((variation, err) -> {
		// your code here
}).join();

getVariableValue

Value for given Taplytics Dynamic Variable. If a user is not in an experiment containing the variable, the response be the provided default value in the query params.

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
varName	Required	name of variable
defaultValue	Required	default value to be used if user does not have variable available.
attributes	Optional	All relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
String varName = "varName";
String defaultValue = "defaultValue";

JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.getVariableValue(userId, varName, defaultValue, attributes)
	.handle((value, err) -> {
		// your code here
}).join();

sendEvent

Send an event to Taplytics. These events are then used to compare against an experiment's goals to determine the success of an A/B test.

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
body	Optional	Provide an array of events, as well as all additional relevant user attributes.
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
JSONObject body = new JSONObject();

JSONObject event = new JSONObject();
event.put("eventName", "event1");
event.put("eventValue", 3);

JSONArray events = new JSONArray();
events.put(event);
body.put("events", events);

taplytics.sendEvent(userId, body)
	.handle((response, err) -> {
		// your code here
}).join();

getConfig

Returns the entire configuration for the project. This is the document that informs the experiment information such as segmentation. Extremely verbose and should be used for debugging.

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
attributes	Optional	All relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.getConfig(userId, attributes)
	.handle((config, err) -> {
		// your code here
}).join();

getFeatureFlags

Returns array of all the enabled feature flags for this project. Each object in the array has name for the name of the feature flag and keyName for the feature flag's key to be used in your code

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
attributes	Optional	All relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.getFeatureFlags(userId, attributes
	.handle((featureFlags, err) -> {
		// your code here
}).join();

isFeatureFlagEnabled

Returns true or false depending if the keyName provided corresponds to an enabled featureFlag in your Taplytics project

Parameters

Parameter	Tags	Description
userId	Required	ID for given user
keyName	Required	Key name for the feature flag
attributes	Optional	All relevant attributes associated with the user
callback	Optional	Provide a callback if you don't want to use a promise

Example Usage

String userId = "user_id";
JSONObject attributes = new JSONObject();
attributes.put("key", "value");

taplytics.isFeatureFlagEnabled(userId, attributes)
	.handle((enabled, err) -> {
		if ((Boolean) enabled) {
			enableFeature();
		}
}).join();
