Tracking Events

Tracking Events
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.
Growlytics 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.
Important!
Please note that the attribute, sdk_id (referred to as 'Platform' on your Growlytics dashboard) of Custom Events signifies the SDK type.
​
sdk_id 1 = Web
sdk_id 2 = Android
sdk_id 3 = iOS
Tracking Custom Events
All event related APIs are part of Growlytics iOS SDK's WEGAnalytics object. Here's how you get an instance of the Growlytics GrowAnalytics object:
Swift
Objective-C
import Growlytics
let GrowAnalytics: GROWAnalytics = Growlytics.sharedInstance().analytics
// import Growlytics ‘Analytics’
#import <Growlytics/GrowAnalytics.h>
​
// Get an instance of ‘Analytics’ object
id<GROWAnalytics> GrowAnalytics = [Growlytics sharedInstance].analytics;
Guidelines
Here are a few things to keep in mind:
Growlytics sends all events data periodically in batches to minimize network usage and maximize mobile battery life for your users.
Custom Event and 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 Growlytics. 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, NSDate, NSArray. You can also add Boolean attributes since its wrapped type is NSNumber.
You can create a maximum of 25 Event Attributes of each data type for a Custom Event.
If an Event Attribute value is NSArray or NSDictionary, then it cannot be used to create segments. It can only be used to personalize campaigns.
The first datapoint synced to Growlytics 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 Growlytics dashboard.
After Growlytics has been successfully initialized, you can track a Custom Event in the following manner:
Swift
Objective-C
growAnalytics.trackEvent(withName: "Product - Page Viewed")
[growAnalytics 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:
Swift
Objective-C
let addedToCartAttributes: [String:Any]  = [
	"Product ID": 1337, 
	"Price": 39.80, 
	"Quantity": 1, 
	"Product": "Givenchy Pour Homme Cologne", 
	"Category": "Fragrance", 
	"Currency": "USD",
	"Is Premium": true
]
growAnalytics.trackEvent(withName: "Added to Cart", andValue: addedToCartAttributes)
​
var comps = DateComponents()
comps.day = 6
comps.month = 10
comps.year = 2017
let deliveryDate: Date = Calendar.current.date(from: comps)!
let orderPlacedAttributes : [String:Any] = [
	"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": deliveryDate, 
  "Delivery City": "San Francisco", 
  "Delivery ZIP": "94121", 
  "Coupon Applied": "BOGO17"
]
growAnalytics.trackEvent(withName: "Order Placed", andValue: orderPlacedAttributes)
NSDictionary *[email protected]{
  @"Product ID":@1337,
  @"Price":@39.80,
  @"Quantity":@1,
  @"Product":@"Givenchy Pour Homme Cologne",
  @"Category":@"Fragrance",
  @"Currency":@"USD",
  @"Is Premium":@YES
};
[growAnalytics trackEventWithName:@"Added to Cart" andValue:addedToCartAttributes];
​
​
NSDateComponents *comps = [[NSDateComponents alloc] init];
        [comps setDay:6];
        [comps setMonth:10];
        [comps setYear:2017];
        NSDate *deliveryDate = [[NSCalendar currentCalendar] dateFromComponents:comps];
​
NSDictionary *orderPlacedAttributes = @{
  @"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":deliveryDate,
  @"Delivery City":@"San Francisco",
  @"Delivery ZIP":@"94121",
  @"Coupon Applied":@"BOGO17"
};
[growAnalytics trackEventWithName:@"Order Placed" andValue:orderPlacedAttributes];
Tracking Complex Event Attributes
Growlytics allows you to pass complex event attributes as NSArray 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 Growlytics account:
Swift
Objective-C
let detailsProduct1 = ["Size": "L"]
let product1 : [String:Any] = ["SKU Code": "UHUH799", "Product Name": "Armani Jeans", "Price": 300.49, "Details": detailsProduct1]
let detailsProduct2 = ["Size": "L"]
let product2 : [String:Any] = ["SKU Code": "FBHG746", "Product Name": "Hugo Boss Jacket", "Price": 507.99, "Details": detailsProduct2]
let deliveryAddress = ["City": "San Francisco", "ZIP": "94121"]
var orderPlacedAttributes = ["Products": [product1, product2], "Delivery Address": deliveryAddress, "Coupons Applied": ["BOGO17"]]
growAnalytics.trackEvent(withName: "Order Placed", andValue: orderPlacedAttributes)
NSDictionary *[email protected]{
  @"Size":@"L"
};
​
NSDictionary *[email protected]{
  @"SKU Code":@"UHUH799",
  @"Product Name":@"Armani Jeans",
  @"Price":@300.49,
  @"Details":detailsProduct1
};
​
NSDictionary *[email protected]{
  @"Size":@"L"
};
​
NSDictionary *[email protected]{
  @"SKU Code":@"FBHG746",
  @"Product Name":@"Hugo Boss Jacket",
  @"Price":@507.99,
  @"Details":detailsProduct2
};
​
NSDictionary *[email protected]{
  @"City":@"San Francisco",
  @"ZIP":@"94121"
};
​
NSDictionary *[email protected]{
  @"Products":@[product1, product2],
  @"Delivery Address":deliveryAddress,
  @"Coupons Applied":@[@"BOGO17"]
};
​
[growAnalytics trackEventWithName:@"Order Placed" andValue:orderPlacedAttributes];
