Tracking Events

Track crucial user-app interactions as Custom Events to engage them with contextually relevant messages


Must Read

We recommend that you get yourself acquainted with the concept of System Events, Custom Events and their attributes before proceeding.

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

As shown below, Custom Events can be tracked using the WebEngage.TrackEvent method of our Unity.iOS SDK.

using WebEngageBridge;

    // Track simple event
    WebEngage.TrackEvent("Product - Page Viewed");


Here are a few things to keep in mind:

  • 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.

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

  • 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.

Tracking Event Attributes

You can track Event Attributes along with a Custom Event in the following manner:

using WebEngageBridge;
    // Track event with attributes
    Dictionary<string, object> orderPlacedAttributes = new Dictionary<string, object>();
    orderPlacedAttributes.Add("Amount", 808.48);
    orderPlacedAttributes.Add("Product 1 SKU Code", "UHUH799");
    orderPlacedAttributes.Add("Product 1 Name", "Armani Jeans");
    orderPlacedAttributes.Add("Product 1 Price", 300.49);
    orderPlacedAttributes.Add("Product 1 Size", "L");
    orderPlacedAttributes.Add("Product 2 SKU Code", "FBHG746");
    orderPlacedAttributes.Add("Product 2 Name", "Hugo Boss Jacket");
    orderPlacedAttributes.Add("Product 2 Price", 507.99);
    orderPlacedAttributes.Add("Product 2 Size", "L");
    orderPlacedAttributes.Add("Delivery Date", System.DateTime.ParseExact("2017-10-21 09:27:37.100", "yyyy-MM-dd HH:mm:ss.fff", null));
    orderPlacedAttributes.Add("Delivery City", "San Francisco");
    orderPlacedAttributes.Add("Delivery ZIP", "94121");
    orderPlacedAttributes.Add("Coupon Applied", "BOGO17");
    WebEngage.TrackEvent("Order Placed", orderPlacedAttributes);

Tracking Complex Events

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

For example, in the below code snippet, we're tracking event attributes of the event, Order Placed, where 2 products have been purchased by a user.

using WebEngageBridge;
      // Track complex event
    Dictionary<string, object> product1 = new Dictionary<string, object>();
    product1.Add("SKU Code", "UHUH799");
    product1.Add("Product Name", "Armani Jeans");
    product1.Add("Price", 300.49);

    Dictionary<string, object> detailsProduct1 = new Dictionary<string, object>();
    detailsProduct1.Add("Size", "L");
    product1.Add("Details", detailsProduct1);

    Dictionary<string, object> product2 = new Dictionary<string, object>();
    product2.Add("SKU Code", "FBHG746");
    product2.Add("Product Name", "Hugo Boss Jacket");
    product2.Add("Price", 507.99);

    Dictionary<string, object> detailsProduct2 = new Dictionary<string, object>();
    detailsProduct2.Add("Size", "L");
    product2.Add("Details", detailsProduct2);

    Dictionary<string, object> deliveryAddress = new Dictionary<string, object>();
    deliveryAddress.Add("City", "San Francisco");
    deliveryAddress.Add("ZIP", "94121");

    Dictionary<string, object> orderPlacedAttributes = new Dictionary<string, object>();
    List<object> products = new List<object>();

    List<string> coupons = new List<string>();

    orderPlacedAttributes.Add("Products", products);
    orderPlacedAttributes.Add("Delivery Address", deliveryAddress);
    orderPlacedAttributes.Add("Coupons Applied", coupons);

    WebEngage.TrackEvent("Order Placed", orderPlacedAttributes);
