Event Collection in iOS SDK

In order to collect app events and use that data to create behavioral segments in D·engage you have to determine the type of events and data that needs to collected. Once you have determined that, you will need to create a “Big Data” table in D·engage. Collected events will be stored in this table. Multiple tables can be defined depending on your specific need.

Any type of event can be collected. The content and the structure of the events are completely flexible and can be changed according to unique business requirements. You will just need to define a table for events.

Once defined, all you have to do is to send the event data to these tables. D·engage SDK has only two functions for sending events: sendDeviceEvent and sendCustomEvent. Most of the time you will just need the sendDeviceEvent function. For ecommerce accounts there is predefined event tables. And you can feed these tables by usern ecommerce event functions.

1. Login / Logout Action

If the user loggs in or you have user information, this means you have contact_key for that user. You can set contact_key in order to match user with the browser. There are two functions for getting and setting contact_key.

setContactKey

If user logged in set user id. This is important for identifying your users. You can put this function call in every page. It will not send unnecessary events.

Dengage.setContactKey(contactKey: "userId")

getContactKey

If you need to get current user information from SDK use this function.

var userId = Dengage.getContactKey()

2. Event Collection

If your D·engage account is an ecommerce account, you should use standart ecommerce events in the SDK. If you need some custom events or your account is not standart ecommerce account, you should use custom event functions.

a) Events for Ecommerce Accounts

For there event there is related tables in your account.

Page View Events

Page view events will be sent to page_view_events table. If you add new columns to this table. You can send these in the event data.

// Home page view
DengageEvent.shared.pageView(params: [
    "page_type":"home"
    // ... extra columns in page_view_events table, can be added here
])

// Category page view
DengageEvent.shared.pageView(params: [
    "page_type":"category",
    "category_id":"1"
    // ... extra columns in page_view_events table, can be added here
])

// Product page view
DengageEvent.shared.pageView(params: [
    "page_type":"product",
    "product_id":"1"
    // ... extra columns in page_view_events table, can be added here
])

//promotion page view
DengageEvent.shared.pageView(params: [
    "page_type":"promotion",
    "promotion_id":"1"
    // ... extra columns in page_view_events table, can be added here
])

//custom page view
DengageEvent.shared.pageView(params: [
    "page_type":"custom"
    // ... extra columns in page_view_events table, can be added here
])

// For other pages you can send anything as page_type

Shopping Cart Events

These events will be stored in shopping_cart_events and shopping_cart_events_detail. There are 4 shopping cart event functions. addToCart, removeFromCart, viewCart, beginCheckout Every shopping cart event function needs all items in cart as an array. You must send last version of the shopping cart.

For example: If there is one item in cart and item id is 5. And after that, an add to cart action is happened with the item id 10. You have to send 10 as product_id in event parameters and you must send current version of cart items. Meaning [5, 10]

// All items currently exists in shopping cart must be added to an array

var cartItem = [:] as NSMutableDictionary

cartItem["product_id"] = 1
cartItem["product_variant_id"] = 1
cartItem["quantity"] = 1
cartItem["unit_price"] = 10.00
cartItem["discounted_price"] = 9.99
// ... extra columns in shopping_cart_events_detail table, can be added in cartItem

let cartItems = [] as [NSMutableDictionary]
cartItems.append(cartItem) 
cartItems.append(cartItem2) 
// ... shopping cart items must be added


// Add to cart action
var params = [
    "product_id":1,
    "product_variant_id":1,
    "quantity":1,
    "unit_price":10.00,
    "discounted_price":9.99,
    // ... extra columns in shopping_cart_events table, can be added here
    "cartItems":cartItems // all items in cart
]
DengageEvent.shared.addToCart(params : params)

// Remove from cart action
var params = [
    "product_id":1,
    "product_variant_id":1,
    "quantity":1,
    "unit_price":10.00,
    "discounted_price":9.99,
    // ... extra columns in shopping_cart_events table, can be added here
    "cartItems":cartItems // all items in cart
]
DengageEvent.shared.removeFromCart(params : params)

// view cart action
var params = [
    // ... extra columns in shopping_cart_events table, can be added here
    "cartItems":cartItems
]
DengageEvent.shared.viewCart(params : params)

// begin checkout action
var params = [
    // ... extra columns in shopping_cart_events table, can be added here
    "cartItems":cartItems
]
DengageEvent.shared.beginCheckout(params : params)

Order Events

Orders events will be sent to order_events and order_events_detail tables.

// Ordered items or canceled items must be added to an array

var cartItem = [:] as NSMutableDictionary

cartItem["product_id"] = 1
cartItem["product_variant_id"] = 1
cartItem["quantity"] = 1
cartItem["unit_price"] = 10.00
cartItem["discounted_price"] = 9.99
// ... extra columns in order_events_detail table, can be added in cartItem

let cartItems = [] as [NSMutableDictionary]
cartItems.append(cartItem) 
cartItems.append(cartItem2) 
// ... ordered or canceled items must be added

// Place order action
var params = [
    "order_id":1,
    "item_count":1, // total ordered item count
    "total_amount":1, // total price
    "discounted_price":9.99, // use total price if there is no discount
    "payment_method":"card",
    "shipping":5,
    "coupon_code":"",
    // ... extra columns in order_events table, can be added here
    "cartItems":cartItems //ordered items
]
DengageEvent.shared.order(params : params)

// Cancel order action
var params = [
    "order_id":1, // canceled order id
    "item_count":1, // canceled total item count
    "total_amount":1, // canceled item's total price
    "discounted_price":9.99, // use total price if there is no discount
    // ... extra columns in order_events table, can be added here
    "cartItems":cartItems // // canceled items 
]
DengageEvent.shared.cancelOrder(params : params)

DengageEvent.shared.search(params : params)

Wishlist Events

// Current items in wishlist
var wishListItem = [:] as NSMutableDictionary
wishListItem["product_id"] = 1

let wishListItems = [] as [NSMutableDictionary]
wishListItems.append(wishListItem)


// Add to wishlist action
var params = [
    "product_id":1,

    "items":wishlistItems // current items
]
DengageEvent.shared.removeFromWishList(params : params)

b) Custom Events

Send device specific events

You can use sendDeviceEvent function for sending events for the device. Events are sent to a big data table defined in your D·engage account. That table must have relation to the master_device table. If you set contact_key for that device. Collected events will be associated for that user.

dengage(‘sendDeviceEvent’, tableName, dataObject [, callback]);

// for example if you have a table named "events"
// and events table has "key", "event_date", "event_name", "product_id" columns
// you just have to send the columns except "key" and "event_date", because those columns sent by the SDK

let params = [
    "event_name": "page_view", 
    "product_id": "1234",
]
Dengage.SendDeviceEvent(toEventTable: 'events', andWithEventDetails: params)
