Branch Metrics React Native SDK Reference

This is a repository of our open source React Native SDK. Huge shoutout to our friends at Dispatcher, Inc. for their help in compiling the initial version of this SDK. This SDK will help you handle iOS Universal Links, Android App Links and deferred deep links, do install attribution and much more!

2.0.0 beta

Version 2.0.0-beta.3 is now available in NPM with a simplified SDK integration process. See Release 2.0.0 for details.

v1.1.0 The createBranchUniversalObject method is now async, so be sure to use await or handle the promise resolution, e.g.

let buo = await branch.createBranchUniversalObject(...)

or

branch.createBranchUniversalObject(...).then((buo) => {
  this.buo = buo
})

This method does not throw.

react-native v0.40 support is available in version 1.x. This is a non-backwards compatible update. If you need to stay on react-native <0.40 please fix your package.json version to react-native-branch@0.9. See Updating to 1.0.0 for details. Note that some build steps differ between 0.9 and 1.x. These are highlighted where applicable.

v0.8.0 If you have overridden onStop in MainActivity.java be sure not to invoke RNBranchModule.onStop().

Installation

For beta version 2.0.0 see Release 2.0.0. These instructions are for 0.9 and 1.x.

1. npm install --save react-native-branch
2. react-native link react-native-branch or link the project manually
3. Add pod 'Branch' to your ios/Podfile (details)
4. cd ios; pod install --repo-update
5. Follow the setup instructions

Note that CocoaPods 1.x no longer automatically updates pod repositories automatically on pod install. To make sure you get the latest version of the Branch SDK, use --repo-update or run pod repo update before pod install.

If you are new to react-native or CocoaPods, read below for more details:

• Full Installation Instructions
• If you already have React in your Podfile
• If you do not know what a Podfile is

Carthage

If you would prefer to use Carthage, you can skip steps 3 & 4 above and instead add the following to your Cartfile:

github "BranchMetrics/ios-branch-deep-linking"

Then run:

carthage update

If you're unfamiliar with how to add a framework to your project with Carthage, you can learn more here. You will need to maually link the framework by adding it to the "Linked Frameworks and Libraries" section of your target settings, and copy it by adding it to the "Input Files" section of your carthage copy-frameworks build phase.

Next Steps

In order to get full Branch support you will need to setup your ios and android projects accordingly:

• iOS
• Android

Please see the Branch SDK Integration Guide for complete setup instructions.

Usage

import branch, {
  AddToCartEvent,
  AddToWishlistEvent,
  PurchasedEvent,
  PurchaseInitiatedEvent,
  RegisterViewEvent,
  ShareCompletedEvent,
  ShareInitiatedEvent
} from 'react-native-branch'

// Subscribe to incoming links (both Branch & non-Branch)
// bundle = object with: {params, error, uri}
branch.subscribe((bundle) => {
  if (bundle && bundle.params && !bundle.error) {
  	// grab deep link data and route appropriately.
  }
})

let lastParams = await branch.getLatestReferringParams() // params from last open
let installParams = await branch.getFirstReferringParams() // params from original install
branch.setIdentity('theUserId')
branch.userCompletedAction('Purchased Item', {item: 123})
branch.logout()

let branchUniversalObject = await branch.createBranchUniversalObject('canonicalIdentifier', {
  automaticallyListOnSpotlight: true,
  metadata: {prop1: 'test', prop2: 'abc'},
  title: 'Cool Content!',
  contentDescription: 'Cool Content Description'})
branchUniversalObject.userCompletedAction(RegisterViewEvent)
branchUniversalObject.userCompletedAction('Custom Action', { key: 'value' })

let shareOptions = { messageHeader: 'Check this out', messageBody: 'No really, check this out!' }
let linkProperties = { feature: 'share', channel: 'RNApp' }
let controlParams = { $desktop_url: 'http://example.com/home', $ios_url: 'http://example.com/ios' }
let {channel, completed, error} = await branchUniversalObject.showShareSheet(shareOptions, linkProperties, controlParams)
let {url} = await branchUniversalObject.generateShortUrl(linkProperties, controlParams)
let spotlightResult = await branchUniversalObject.listOnSpotlight()

// optional: release native resources right away when finished with this BUO.
branchUniversalObject.release()

let rewards = await branch.loadRewards()
let redeemResult = await branch.redeemRewards(amount, bucket)
let creditHistory = await branch.getCreditHistory()

Linking

subscribe(listener)

listener (function)
Adds a change listener. Listener takes 1 argument with the shape { params, uri, error}. The listener will be called for all incoming links. Branch links will have params, plain deep links will only have a uri.

getLatestReferringParams(): Promise

Returns a promise that resolves to the most recent referring params. Because params come in asynchronously, in most cases it is better to use the subscribe method to receive the params as soon as they are available.

getFirstReferringParams(): Promise

Returns a promise to resolves with the first install referring params.

params object

The params object is returned by various linking methods including subscribe, getLatestReferringParams, and getFirstReferringParams. Params will contain any data associated with the Branch link that was clicked before the app session began.

Branch returns explicit parameters every time. Here is a list, and a description of what each represents.

• ~ denotes analytics
• + denotes information added by Branch

Parameter	Meaning
~channel	The channel on which the link was shared, specified at link creation time
~feature	The feature, such as invite or share, specified at link creation time
~tags	Any tags, specified at link creation time
~campaign	The campaign the link is associated with, specified at link creation time
~stage	The stage, specified at link creation time
~creation_source	Where the link was created ('API', 'Dashboard', 'SDK', 'iOS SDK', 'Android SDK', or 'Web SDK')
~referring_link	The referring link that drove the install/open, if present
~id	Automatically generated 18 digit ID number for the link that drove the install/open, if present
+match_guaranteed	True or false as to whether the match was made with 100% accuracy
+referrer	The referrer for the link click, if a link was clicked
+phone_number	The phone number of the user, if the user texted himself/herself the app
+is_first_session	Denotes whether this is the first session (install) or any other session (open)
+clicked_branch_link	Denotes whether or not the user clicked a Branch link that triggered this session
+click_timestamp	Epoch timestamp of when the click occurred
+url	The full URL of the link that drove the install/open, if present (e.g. bnc.lt/m/abcde12345)

See also Deep Link Routing on the Branch documentation site for more information.

Any additional data attached to the Branch link will be available unprefixed.

User Methods

setIdentity(userId)

Set an identifier for the current user.

logout(userId)

Logout the current user.

userCompletedAction(label, payload)

Register a user action with Branch.

Branch Universal Object

createBranchUniversalObject(canonicalIdentifier, universalObjectOptions): Promise

Create a branch universal object.
canonicalIdentifier the unique identifier for the content.
universalObjectOptions options for universal object as defined below.
Returns a promise. On resolution, the promise returns an object with methods generateShortUrl, registerView, listOnSpotlight, showShareSheet, userCompletedAction (v1.1.0) and release (v1.1.0). This method does not throw.

The following methods are available on the resulting branchUniversalObject:

- userCompletedAction(event, state = {}): null

Introduced in version 1.1.0

Report a user action for this Branch Universal Object instance. Create a Branch Universal Object on page load and call userCompletedAction(RegisterViewEvent).

event an event name string, either one of the standard events defined by the SDK (as defined below) or a custom event name.
state an optional object with string properties representing custom application state

Returns null.

- showShareSheet(shareOptions, linkProperties, controlParams): object

shareOptions as defined below
linkProperties as defined below
controlParams as defined below
Returns an object with { channel, completed, error }

- generateShortUrl(linkProperties, controlParams): object

linkProperties as defined below
controlParams as defined below
Returns an object with { url }

- registerView()

Register a view for this universal object. Deprecated: Use userCompletedAction(RegisterViewEvent) instead.

- listOnSpotlight()

List the universal object on Spotlight (iOS only). Note: The recommended way to list an item on Spotlight is to use the automaticallyListOnSpotlight property with createBranchUniversalObject and then call userCompletedAction(RegisterViewEvent), e.g.

import branch, { RegisterViewEvent } from 'react-native-branch'

let universalObject = await branch.createBranchUniversalObject('abc', {
  automaticallyListOnSpotlight: true,
  title: 'Item title',
  contentDescription: 'Item description',
  contentImageUrl: 'https://example.com/image.png'
})
universalObject.userCompletedAction(RegisterViewEvent)

The automaticallyListOnSpotlight property is ignored on Android.

- release()

Introduced in version 1.1.0

(Optional) Immediately release native resources used by this Branch Universal Object instance. Those resources will eventually be removed if they are unused for some time, but you can also call release() when a BUO is no longer used, e.g. in componentWillUnmount(). (See the example apps in this repo.)

Register User Actions On An Object

We've added a series of custom events that you'll want to start tracking for rich analytics and targeting. Here's a list below with a sample snippet that calls the register view event.

Event	Description
RegisterViewEvent	User viewed the object
AddToWishlistEvent	User added the object to their wishlist
AddToCartEvent	User added object to cart
PurchaseInitiatedEvent	User started to check out
PurchasedEvent	User purchased the item
ShareInitiatedEvent	User started to share the object
ShareCompletedEvent	User completed a share

import branch, { RegisterViewEvent } from 'react-native-branch'
let universalObject = await branch.createUniversalObject('abc', {})
universalObject.userCompletedAction(RegisterViewEvent)

Note that registerView() is deprecated in favor of userCompletedAction(RegisterViewEvent).

universalObjectOptions object

An object of options for the branchUniversalObject.

Key	TYPE	DESCRIPTION
automaticallyListOnSpotlight	Bool	List this item on Spotlight (iOS). Ignored on Android.
canonicalIdentifier	String	The object identifier
contentDescription	String	Object Description
contentImageUrl	String	The Image URL
contentIndexingMode	String	Indexing Mode 'private' or 'public'
currency	String	A 3-letter ISO currency code (used with price)
expirationDate	String	A UTC expiration date, e.g. 2018-02-01T00:00:00
keywords	Array	An array of keyword strings
metadata	Object	Custom key/value
price	Float	A floating-point price (used with currency)
title	String	The object title
type	String	MIME type for this content

linkProperties object

An object of link properties.

KEY	TYPE	MEANING
alias	string	Specify a link alias in place of the standard encoded short URL (e.g., [branchsubdomain]/youralias or yourdomain.co/youralias). Link aliases are unique, immutable objects that cannot be deleted. Aliases on the legacy bnc.lt domain are incompatible with Universal Links and Spotlight
campaign	string	Use this field to organize the links by actual campaign. For example, if you launched a new feature or product and want to run a campaign around that
channel	string	Use channel to tag the route that your link reaches users. For example, tag links with ‘Facebook’ or ‘LinkedIn’ to help track clicks and installs through those paths separately
feature	string	This is the feature of your app that the link might be associated with. eg: if you had built a referral program, you would label links with the feature referral
stage	string	Use this to categorize the progress or category of a user when the link was generated. For example, if you had an invite system accessible on level 1, level 3 and 5, you could differentiate links generated at each level with this parameter
tags	array	This is a free form entry with unlimited values. Use it to organize your link data with labels that don’t fit within the bounds of the above

controlParams object

Control parameters for the link. All Branch control parameters are supported. See here for a complete list. In particular, these control parameters determine where the link redirects.

KEY	TYPE	MEANING
$fallback_url	string	Change the redirect endpoint for all platforms - so you don’t have to enable it by platform
$desktop_url	string	Change the redirect endpoint on desktops
$android_url	string	Change the redirect endpoint for Android
$ios_url	string	Change the redirect endpoint for iOS
$ipad_url	string	Change the redirect endpoint for iPads

$windows_phone_url	string	Change the redirect endpoint for Windows OS

shareOptions object

KEY	TYPE	MEANING
messageHeader	string	The header text
messageBody	string	The body text
emailSubject	string	The subject of the email channel if selected
