Overview

By default, the Branch SDK tracks clicks, opens, installs, reinstalls and impressions automatically (out-of-the-box).

Similarly, the Branch Web SDK tracks pageviews, web session starts, clicks, and impressions automatically (out-of-the-box).

We've also standardized the way you track "classes" of events. For example: all events related to a customer purchasing are bucketed into a "purchase" class of data items, and all events related to users interacting with your in-app content are linked to a "content" class of data items.

Below are examples of the kinds of events you'll likely be interested in tracking, and we'll show you the way to track through our SDKs.

Events for Optimization

When Universal Ads is enabled, tracking these events will postback to the attributed Ad Network. For example, if you track the purchase event through Branch, this will automatically map to Facebook's Purchase event if the user is attributed to Facebook.

These events will also have analytics like counts and cohorts, so you can understand their performance even when using SafeTrack Attribution.

Available Events

🚧
Event Tracking Disclaimer
Branch may implement caps/overages on the number of events you are tracking. We recommend that you only track events that are useful for your analytics and attribution needs. Additionally, this will avoid unnecessary network calls that your app will make leading to better app performance.

📘
Facebook Ads Support
If you are sending any event Server to Server to Branch and are running Facebook campaigns on iOS, it is required to send the OS version for Branch to provide attribution on Facebook ads.

Custom Events

Custom Events can be tracked if the event does not fall within one of the categories above.

Note: Custom data in the Branch dashboard is viewable in Liveview and Exports.

Track Commerce Events

Commerce events describe events that relate to a customer interacting with your products and converting by purchasing. These are events like adding payment information, purchasing, viewing products, etc. If you have enabled Branch Universal Ads, these events will automatically map to certain Ad Partners. Start by creating a Branch Universal Object for each product that is associated with the event you're tracking.

From there, add the Branch universal object to the tracked event, and use the right predefined constant. For example, the code snippet below is to track when a user adds to cart, but simply replace that constant with another constant to track a different event.

📘
Currency and Exchange Rates
If you track commerce events without a currency, we assume they are USD. If you track commerce events with a currency other than USD, we will convert the revenue specified to USD using a recent exchange rate.
This allows you to easily visualize revenue on the Dashboard across many countries and currencies because all units are USD. The exchange rate is pulled from openexchangerates.org regularly and is generally within an hour of the real-time exchange rate. If you view raw Branch events via either Webhooks or Exports, you can see the exchange rate used.

Track Content Events

Content events are events that occur when a user engages with your in-app content. For example, if you have in-app articles, you would want to track events related to when users search, view content, rate the content, and share. This can apply to a wide variety of in-app content, such as blog posts, music, video, pictures, and e-commerce catalogue items.

HTTP API - Content Endpoint

POST /v2/event/standard
Content-Type: application/json

Parameters

Note about required identifiers. You must send up (in user_data):

browser_fingerprint_id OR
os=iOS AND (idfa OR idfv) OR
os=Android AND (android_id or aaid)

Example - Content

let event = BranchEvent.standardEvent(.search)
event.alias = "my custom alias"
event.eventDescription = "Product Search"
event.searchQuery = "user search query terms for product xyz"
event.customData["Custom_Event_Property_Key1"] = "Custom_Event_Property_val1"
event.logEvent()

BranchEvent *event = [BranchEvent standardEvent:BranchStandardEventSearch];

event.searchQuery = @"user search query terms for product xyz";

Track Lifecycle Events

Lifecycle events can be described as events a user takes in your app to continue progressing. These events can apply to game apps, as well as non game apps, for when a user completes a user profile, registration or tutorial.

HTTP API - Lifecycle Endpoint

POST /v2/event/standard
Content-Type: application/json

Parameters

Note about required identifiers. You must send up (in user_data):

browser_fingerprint_id OR
os=iOS AND (idfa OR idfv) OR

Track Custom Events

If you want to track an event that isn't a predefined event, simply do the following:

📘
Custom Event Names
The name custom event is reserved by Branch. Please ensure you give your custom event an actual name.
Additionally, do not use the same name for your custom event as Standard Events. This will have an impact on attribution with Self-Attributing Networks and event mapping.

We strongly recommend using custom event names that contain no more than 40 characters, contain only letters, numbers, hyphens, spaces, and underscores, and do not start with a hyphen. Facebook will not accept events that violate these rules, and if you enable the Facebook integration, Branch may sanitize your event names to pass validation.

HTTP API - Custom Endpoint

POST /v2/event/custom
Content-Type: application/json

Parameters

Note about required identifiers. You must send up (in user_data):

browser_fingerprint_id OR
os=iOS AND (idfa OR idfv) OR
os=Android AND (android_id or aaid)

Example - Custom
