FullStory Segment Middleware iOS

Segment is a customer data platform that unifies data collection and provides data to every team in your company. The middleware is an easy way to integrate FullStory with the Segment Analytics for iOS SDK.

With minimal code changes, the FullStory Segment Middleware provides developers the ability to send Segment Analytics data to FullStory, and adds FullStory session replay links to Segment events.

Sending data to FullStory using Middleware

Handle Login/Logout

Identify a user and their traits at login

Similar to FS.identify, Segment has an Analytics.identify API that lets you tie a user’s identity to their actions and recordings in order to help you understand their journey.

With this API, you can also record what Segment calls traits (userVars in FullStory) about your users, like their email, name, preferences, etc.

The middleware automatically hooks into the Analytics.identify Segment API that sends user ID and traits to FullStory.

Anonymize the user at logout

If your app supports login/logout, then you need to anonymize logged in users when they log out by calling Analytics.reset to clear Segment cache and anonymize this user.

Alternatively, you can manually call FS.anonymize after Analytics.reset; see the "Manual Client side integration" section below for more information.

Custom events

Similar to identify, we can automatically hook into Analytics.track and Analytics.screen events and funnel the data to FullStory session replay.

Note that by default, no track or screen events are recorded as custom events. Learn more about our Privacy by Default approach.

When initiating the middleware, allowlist the events that you would like to send to FullStory. If you wish to enable all events, set allowlistAllTrackEvents to true. See below section "Implementation Guide" for code examples.

We will log to FullStory that a Segment API is called but omit all data if the event is not allowlisted.

All custom events are searchable in FullStory. You can find and view sessions that match your search criteria.

Add FS session replay URL to Segment events using Middleware

With FullStory for Mobile Apps, you can retrieve a link to the session replay and attach it to any Segment event.

By default we automatically insert the FullStory session replay URL as part of the Segment track and screen event properties, and all event contexts.
Depending on the destinations, some may receive only properties, others may be able to parse information in event context.
This enables you to receive FullStory session replay links at your destinations and easily identify and navigate to the session of interest.
You can disable this behavior by setting enableFSSessionURLInEvent to false

Implementation Guide

Before you begin, make sure you have both FullStory and Segment setup in your application:
- Add FullStory to your iOS app: Getting Started with iOS Recording
- Use CocoaPods to add to project:
```
pod 'FullStorySegmentMiddleware', :git => 'https://github.com/fullstorydev/fullstory-segment-middleware-ios.git',:tag => '1.2.2'
```
- Alternatively, download the files manually:
  - Add the files inside FullStoryMiddleware to your iOS project

Add the middleware during the initialization of your segment analytics client to enable FullStory.

Create FullStoryMiddleware with appropriate settings

let fullStoryMiddleware: FullStoryMiddleware
      = FullStoryMiddleware.init(allowlistEvents:
              ["Order Completed",
                "Viewed Checkout Step",
                "Completed Checkout Step"])

// allow all events to be tracked by FS, default is false
fsm.allowlistAllTrackEvents = true
// allow FS session URL to be added in Segemnt event properties, default is true
fsm.enableFSSessionURLInEvents = true
// enable to send group traits as userVars, default is false
fsm.enableGroupTraitsAsUserVars = true
// enable to send FS custom events on screen event, default is false
fsm.enableSendScreenAsEvents = true
// enable Segment identify events to be sent as FS identify event, default is true
fsm.enableIdentifyEvents = true

configuration.middlewares = [fsm]
SEGAnalytics.setup(with: configuration)

Your integration is now ready.
