Installation

PM> Install-Package VWO.Sdk

Basic usage

Using and Instantiation

using VWOSdk;

Settings settingsFile = VWO.GetSettingsFile(accountId, sdkKey);     //  Fetch settingsFile from VWO.
IVWOClient vwoClient = VWO.Launch(settingsFile);           //  Create VWO Client to user APIs.

API usage

using System.Collections.Generic;

// Activate API
// Without Custom Variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>(){};
string variationName = vwoClient.Activate(campaignKey, userId, options);

// With Custom Variable , variation targeting variable
public readonly static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    {
        "customVariables", new Dictionary<string, dynamic>()
        {
            {"price", 100.1}
        },
        "variationTargetingVariables", new Dictionary<string, dynamic>()
        {
            {"team", "qa-internal"}
        }
    }
};

string variationName = vwoClient.Activate(campaignKey, userId, options);

// GetVariationName API
// Without Custom Variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>(){};
string variationName = vwoClient.GetVariationName(campaignKey, userId, options);

// With Custom Variable snd variation targeting variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    {
        "customVariables", new Dictionary<string, dynamic>()
        {
            {"price", '40'}
        }
        "variationTargetingVariables", new Dictionary<string, dynamic>()
        {
            {"team", "qa-internal"}
        }
    }
};
string variationName = vwoClient.GetVariationName(campaignKey, userId, options);

// Track API
// For CUSTOM CONVERSION Goal
bool isSuccessful = vwoClient.Track(campaignKey, userId, goalIdentifier);

// For Goal Conversion in Multiple Campaign
Dictionary<string, bool> result = vwoClient.Track(List <string>() { campaignKey1 campaignKey2 }, userId, goalIdentifier);

// For Goal Conversion in All Possible Campaigns
Dictionary<string, bool> result = vwoClient.Track(userId, goalIdentifier);

// Without Revenue Value and Custom Variable
Dictionary<string, dynamic> options = new Dictionary<string, dynamic>(){};
bool isSuccessful = vwoClient.Track(campaignKey, userId, goalIdentifier, options);

// For only Revenue Value
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    { "revenueValue", 10.2 },
};
bool isSuccessful = vwoClient.Track(campaignKey, userId, goalIdentifier, options);

// For only Custom Variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    {
        "customVariables", new Dictionary<string, dynamic>()
        {
            {"location", 'India'}
        }
    }
};
bool isSuccessful = vwoClient.Track(campaignKey, userId, goalIdentifier, options);

// For Revenue Value and Custom Variable and Variation Targeting varaible
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    {
        "revenue_value", 10
    },
    {
      "customVariables", new Dictionary<string, dynamic>()
      {
          {
            "gender", "f"
          }
      }
    },
    {
      "variationTargetingVariables", new Dictionary<string, dynamic>()
      {
          {
              "abcd", 1
          }
      }
    }
};
bool isSuccessful = vwoClient.Track(campaignKey, userId, goalIdentifier, options);

//IsFeatureEnabled API
//Without Custom Variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>(){};
bool isSuccessful = vwo.Client.IsFeatureEnabled(campaignKey, userId, options);

//With Custom Variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    {
        "customVariables", new Dictionary<string, dynamic>()
        {
            {"value", 10}
        }
    }
};
bool isSuccessful = vwo.Client.IsFeatureEnabled(campaignKey, userId, options);

//GetFeatureVariableValue API
//Without Custom Variable
Dictionary<string, dynamic> options = new Dictionary<string, dynamic>(){};
dynamic variableValue = vwo.Client.GetFeatureVariableValue(campaignKey, variableKey, userId, options);

//With Custom Variable
public static Dictionary<string, dynamic> options = new Dictionary<string, dynamic>()
{
    {
        "customVariables", new Dictionary<string, dynamic>()
        {
            {"value", 10}
        }
    }
};
dynamic variableValue = vwo.Client.GetFeatureVariableValue(campaignKey, variableKey, userId, options);

//Push API
bool isSuccessful = vwo.Client.Push(tagKey, tagValue, userId);

//Pass TagKey
var TagKey = "abc";
bool isSuccessful = vwo.Client.Push(TagKey, tagValue, userId);

//Pass TagValue
var TagValue = "abc";
bool isSuccessful = vwo.Client.Push(tagKey, TagValue, userId);

Configure Log Level

VWO.Configure(LogLevel.DEBUG);

Implement and Configure Custom Logger - implement your own logger class

using VWOSdk;

public class CustomLogWriter : ILogWriter
{
    public void WriteLog(LogLevel logLevel, string message)
    {
        // ...write to file or database or integrate with any third-party service
    }
}

//  Configure Custom Logger with SDK.
VWO.Configure(new CustomLogWriter());

User Storage Service

using VWOSdk;

public class UserStorageService : IUserStorageService
{
    public UserStorageMap Get(string userId)
    {
        // ...code here for getting data
        // return data
    }

    public void Set(UserStorageMap userStorageMap)
    {
        // ...code to persist data
    }
}


var settingsFile = VWO.GetSettingsFile(VWOConfig.AccountId, VWOConfig.SdkKey);

//  Provide UserStorageService instance while vwoClient Instantiation.
var vwoClient = VWO.Launch(settingsFile, userStorageService: new UserStorageService());

//  Set specific goalType to Track
//  Available GoalTypes - GoalTypes.REVENUE, GoalTypes.CUSTOM, GoalTypes.ALL (Default)
var vwoClient = VWO.Launch(settingsFile, goalTypeToTrack: Constants.GoalTypes.REVENUE);

//  Set if a return user should be tracked, default false
var vwoClient = VWO.Launch(settingsFile, shouldTrackReturningUser: true);
