Overview

Event tracking helps you understand how a user moves through your app and what actions they are taking along the way. It's also how you get insight into when a user installs or reinstalls your app.

Some events are tracked automatically by Branch, while others are not. For those that aren't, you'll use the Branch SDK to log the event.

Types of Branch Events

There are 2 main categories of events: Standard and Custom.

Standard Events

Standard Events have properties that are pre-defined by Branch. There are 3 categories of Standard Events: Commerce, Content, and Lifecycle.

Standard Events have the following HTTP API endpoint:

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

Custom Events

Custom Events are for actions you want to track that Branch doesn't have a suitable Standard Event for. You can define your own properties for these types of events.

Custom Events have the following HTTP API endpoint:

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

Automatically Tracked Events

By default, the Branch SDKs track some events automatically (out-of-the-box). See the table below for specifics:

Event	Tracked Automatically by Mobile SDKs	Tracked Automatically by Web SDK
Click	✔️	✔️
Open	✔️	✔️ (called `web_session_start`)
Install	✔️	✔️
Reinstall	✔️	✔️
Impression	✔️	✔️
Journeys Dismissal	N/A	✔️

On web, open events are called web_session_start. This event is triggered every time a webpage with the web SDK opens in a new tab or when a user clicks on a Branch link and is redirected to a page with the web SDK. A user doing things like clearing the browser cache or navigating away from the webpage and the going back to it will reinitiate the web session.

Branch Universal Objects

Branch SDKs use the concept of a Branch Universal Object (BUO) to represent the thing you want to share. A BranchUniversalObject instance encapsulates a unique piece of content, such as an article, video, or item for sale.

When tracking app events, you will sometimes want to create a BUO first and then associate it with a Branch Event by adding the BUO instance to the Branch Event's contentItems field.

Attribution

For proper attribution, you must send certain parameters to Branch alongside these events as part of the user data:

developer_identity OR
browser_fingerprint_id OR
os=iOS AND idfa OR
os=iOS AND idfv OR
os=Android AND android_id OR
os=Android AND aaid

Ad Network Event Mapping

When Universal Ads is enabled, tracking Branch Standard Events will postback to the attributed Ad Network. For example, if you track a Standard PURCHASE Event through Branch, it 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.

Event Tracking

The sections below outline each type of Branch Standard Event, as well as Custom Events. Included are code samples in a range of languages, so you can see how to log that event using your version of the Branch SDK.

🚧
Usage Limitations
Branch may implement caps or overages based on the number of events you are tracking. We recommend that you only track events that are useful for your analytics and attribution needs. This will also avoid unnecessary network calls being made by your app, leading to better app performance.

Track Commerce Events

Commerce Events include purchases and transactions, as well as actions related to carts and wishlists.

If you have Branch Universal Ads enabled, Commerce Events will automatically map to certain Ad Partners.

📘
Currency and Exchange Rates
If you track Commerce Events without a currency, we assume the currency is 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.

Subscription and In-App Purchase Events

The Branch iOS and Android SDKs offer certain methods that make tracking subscription and in-app purchase events simpler. These methods allow you to convert standard purchase events from Apple and Google into a Branch Event without needing to create and populate a Branch Universal Object first.

Track Content Events

Content Events are events that occur when a user engages with your in-app content.

An example could be in-app articles that you post. In that instance, you might want to track events related to users performing search queries, viewing content, rating the content, and sharing it.

Content Events can relate to a wide variety of in-app content, such as blog posts, music, videos, pictures, and e-commerce catalogue items.

Event Name	iOS	Android	Web/API
Search	`BranchStandardEventSearch`	`BRANCH_STANDARD_EVENT.SEARCH`	`SEARCH`
View Item	`BranchStandardEventViewItem`	`BRANCH_STANDARD_EVENT.VIEW_ITEM`	`VIEW_ITEM`
View Items	`BranchStandardEventViewItems`	`BRANCH_STANDARD_EVENT.VIEW_ITEMS`	`VIEW_ITEMS`
Rate	`BranchStandardEventRate`	`BRANCH_STANDARD_EVENT.RATE`	`RATE`
Share	`BranchStandardEventShare`	`BRANCH_STANDARD_EVENT.SHARE`	`SHARE`
Initiate Stream	`BranchStandardEventInitiateStream`	`BRANCH_STANDARD_EVENT.INITIATE_STREAM`	`INITIATE_STREAM`
Complete Stream	`BranchStandardEventCompleteStream`	`BRANCH_STANDARD_EVENT.COMPLETE_STREAM`	`COMPLETE_STREAM`

Track Custom Events

If there isn't a Branch Standard Event that is suitable for the event you want to track, you can create a Custom Event.

Naming

The name custom event is reserved by Branch. Please give your Custom Event a more descriptive name.

Additionally, do not use Standard Event names as the name for your Custom Event.

Examples

// Create event
let event = BranchEvent.customEvent(withName:"User_Scanned_Item")

// Define event data
event.customData["Custom_Event_Property_Key1"] = "Custom_Event_Property_val1"
event.customData["Custom_Event_Property_Key2"] = "Custom_Event_Property_val2"
event.alias = "my custom alias"

// Log event
event.logEvent()

// Create event
BranchEvent *event = [BranchEvent customEventWithName:@"User_Scanned_Item"];

// Define event data
event.customData = (NSMutableDictionary*) @{
    @"Custom_Event_Property_Key1": @"Custom_Event_Property_val1",
    @"Custom_Event_Property_Key2": @"Custom_Event_Property_val2"
};
event.alias = "my custom alias";

// Log event
[event logEvent];

// Create event
new BranchEvent("Some Custom Event")
	.addCustomDataProperty("Custom_Event_Property_Key11", "Custom_Event_Property_val11") // Define event data
	.addCustomDataProperty("Custom_Event_Property_Key22", "Custom_Event_Property_val22")

// Create event
BranchEvent("Some Custom Event")
	.addCustomDataProperty("Custom_Event_Property_Key11", "Custom_Event_Property_val11") // Define event data
	.addCustomDataProperty("Custom_Event_Property_Key22", "Custom_Event_Property_val22")
	.setCustomerEventAlias("my_custom_alias")
	.logEvent(this); // Log event

// Define event data
var custom_data = {
   "Custom_Event_Property_Key1": "Custom_Event_Property_val1",
   "Custom_Event_Property_Key2": "Custom_Event_Property_val2"
};

// Log event
branch.logEvent(

    custom_data,
    function(err) { console.log(err); }
);

// Define event data
