Must Read

We recommend that you get yourself acquainted with the concept of System Events, Custom Events and their attributes before proceeding. Doing so will help you better understand the workings of this section.

Here are a few Custom Event Templates to help you get started.

WebEngage starts tracking some events as soon as you integrate the SDK. These are called System Events and track some generic user interactions with your app and campaigns. Here's a list of the System Events that are automatically tracked by us.

You can create Custom Events to track any other user interactions that are curcial for your business. Each Custom Event can further be defined by Event Attributes like price, quantity, category and so on. Such granular data enables you to engage users through highly contextual and personalized campaigns through all the channels of engagement.

Tracking Custom Events

All Event related APIs are part of WebEngage Xamarin.iOS SDK's Analytics object. Here's how you can get an instance of the WebEngage Analytics object:

// import WebEngage SDK
using WebEngageXamariniOS;

// Get an instance of ‘Analytics’ object
Analytics weAnalytics = WebEngage.SharedInstance().Analytics;

Guidelines

Here are a few things to keep in mind:

  • WebEngage sends all events data periodically in batches to minimize network usage and maximize mobile battery life for your users.

  • Custom Event names must be less than 50 characters long.

  • Custom Event Attribute names are case sensitive and must be less than 50 characters long. String attribute values must be less than 1000 characters long.

  • eventName or eventAttributeName must not start with we_. Names starting with we_ are reserved exclusively for internal use at WebEngage. Thus, to avoid data contamination for your account, such data will be ignored if used for your Custom Events.

  • Custom Event Attributes can be of these data types: NSString, NSNumber, Boolean, NSDate, NSMutableArray and NSDictionary.

  • You can create a maximum of 25 Event Attributes of each data type for a Custom Event.

  • If an Event Attribute value is NSMutableArray or NSDictionary, then it cannot be used to create segments. It can only be used to personalize campaigns.

  • The first datapoint synced to WebEngage defines the data type for that event attribute. Thus, data types must be consistent with the value that you want to store against the attribute. If the data type is changed at a later date, then Custom Event Attribute data will stop flowing to your WebEngage dashboard.

After WebEngage has been successfully initialized, you can track a Custom Event in the following manner:

weAnalytics.TrackEventWithName("Product - Page Viewed");

Tracking Event Attributes

You can use NSDictionary to specify a Custom Event Attribute and attach it to the Custom Event for which you'd like to track it, in the following manner:

var addedToCartAttributes = new NSDictionary("Product ID", 1337, 
                                             "Price", 39.80, 
                                             "Quantity", 1, 
                                             "Product", "Givenchy Pour Homme Cologne",
                                             "Category", "Fragrance",
                                             "Currency", "USD",
                                             "Discounted", true
                                            );
weAnalytics.TrackEventWithName("Added to Cart", addedToCartAttributes);


var orderPlacedAttributes = new NSDictionary("Amount", 808.48, 
                                             "Product 1 SKU Code", "UHUH799", 
                                             "Product 1 Name", "Armani Jeans", 
                                             "Product 1 Price", 300.49,
                                             "Product 1 Size", "L",
                                             "Product 2 SKU Code", "FBHG746",
                                             "Product 2 Name", "Hugo Boss Jacket",
                                             "Product 2 Price", 507.99,
                                             "Product 2 Size", "L",
                                             "Delivery Date", NSCalendar.CurrentCalendar.DateFromComponents(new NSDateComponents
                                              {
                                                  Day = 29,
                                                  Month = 4,
                                                  Year = 2001
                                              }),
                                             "Delivery City", "San Francisco",
                                             "Delivery ZIP", "94121",
                                             "Coupon Applied", "BOGO17"
                                            );
weAnalytics.TrackEventWithName("Order Placed", orderPlacedAttributes);

###Tracking Complex Event Attributes

WebEngage allows you to pass complex event attributes as NSMutableArray and NSDictionary data types. You will be able to use this data to personalize campaigns, as shown below. However, you will not be able to use complex attributes for creating segments.

Here's how you can pass Complex Event Attributes along with a Custom Event to your WebEngage account: 

using WebEngageXamariniOS;

var detailsProduct1 = new NSDictionary("Size", "L");

var product1 = new NSDictionary("SKU Code", "UHUH799",
                                "Product Name", "Armani Jeans",
                                "Price", 300.49,
                                "Details", detailsProduct1
                               );
var detailsProduct2 = new NSDictionary("Size", "L");

var product2 = new NSDictionary("SKU Code", "FBHG746",
                                "Product Name", "Hugo Boss Jacket",
                                "Price", 507.99,
                                "Details", detailsProduct2
                               );
var deliveryAddress = new NSDictionary("City", "San Francisco", 
                                       "ZIP", "94121"
                                      );
var products = new NSMutableArray<NSDictionary>(product1, product2);

var orderPlacedAttributes = new NSDictionary("Products", products,
                                             "Delivery Address", deliveryAddress,
                                             "Coupons Applied", new NSMutableArray<NSString>(new NSString("BOGO17"), new NSString("BGH025"))
                                            );
weAnalytics.TrackEventWithName("Order Placed", orderPlacedAttributes);
