Referring a friend

Referrals can use unique codes or shareable links. Codes are the default; links require a Branch integration for deep-linking and attribution.

Overview

In a referral campaign each user receives a referral code or link to share with friends, and a friend uses that code or link during sign-up, which connects the referral and activates tracking.

This article explains the two options for sharing and registration:

• Code referrals (default) – Each user receives a unique code to share. Friends enter this code at registration.

• Link referrals (optional) – A unique referral link is generated for each user through a Branch.io integration, which they can then share with their friends. Friends join via the link, and Branch handles attribution.

Choosing between codes and links

• Codes → Most reliable, no third parties, built in by default.

• Links → Flexible and seamless for users, but requires external setup and ongoing Branch costs.

Code referrals

Code referrals are the standard approach and included with the Referrals module.

• Each user is given a unique, 8-character alphanumeric code (e.g., 4AD0E5B9).

• If multiple referral campaigns are active, users receive a unique code for each.

• Friends must enter the code during registration to be counted as a valid referral.

• Tracking is fully managed by the Loyalty Engine—no third-party setup required.

Best for: Guaranteed tracking, simple setup, no extra cost.

Link referrals (Branch integration)

For clients who want shareable referral links instead of codes, the Loyalty Engine integrates with Branch.io.

• Branch generates referral links that users can share with friends.

• When clicked, links route users to the correct destination (app store, app, or website).

• Attribution is handled entirely by Branch, tying the referral back to the original user.

• Requires:

  • A Branch account (purchased separately).

  • Branch SDK integrated into your app or website.

Branch key features

• Deep linking – Sends friends directly to the right place, even if the app must be installed first.

• Attribution tracking – Identifies who shared the link and connects their actions.

• Customizable links – Branded URLs that fit your program.

• Real-time reporting – Track link creation, clicks, and conversions.

Best for: Apps already using Branch, or programs wanting branded deep links.
