The VWO client class needs to be instantiated as an instance that exposes various API methods like activate, getVariationName and track.

Each VWO client represents the state of a project corresponding to the settingsFile. SettingsFile needs to be fetched before instantiating a VWO client. Read more on how to get SettingsFile.

API Description

SDK provides a method to instantiate a VWO client as an instance. The method accepts an object to configure the VWO client.

The only required parameter for instantiating the SDK is settings file. There are other optional parameters, which you could provide for overriding the default behavior or setting environment.

Parameter Definitions

Below is the list of all parameters that can be used for configuring the VWO SDK.
