Shopify, Klaviyo, Recharge and every major subscription app, Tremendous and PayPal for payouts, GA4 and the ad pixels you already have. ReferralCandy works inside the tools your team is already in.
Shopify is where ReferralCandy is deepest — one-click install, drag-and-drop blocks in your theme, app blocks in customer accounts. BigCommerce and WooCommerce install in one click too; Magento and custom stores connect by email or API.
Shopify & Shopify Plus
One-click install on the Shopify App Store.
The full ReferralCandy experience — referral programs, affiliate programs, theme app blocks on the thank-you page and inside customer accounts, and the Klaviyo, Recharge, Tremendous and analytics integrations — all wired up natively. Install takes 30 seconds; most merchants are live in an afternoon.
Pipe referral and affiliate activity into the email and messaging platform your team already uses. Your existing journeys stay in place — your referral program gives them new signals to act on.
Klaviyo
Every referral event in your Klaviyo flows.
Every referral event becomes a Klaviyo profile property and a Klaviyo event. Drop the unique referral link, the friend's coupon code, the tier progress, or the friends-referred count into any flow you already run. Trigger new flows when a customer enrolls, refers, gets rewarded, or has their reward leave a 30-day review window.
Sync ReferralCandy audiences into Mailchimp, drop branded referral CTAs into the email builder, and let your existing flows do the work. The customers who already love you become the customers who bring more.
Import everyone or a single Customer.io segment into ReferralCandy, then optionally write each advocate’s unique referral link back to their profile for use in campaigns and newsletters. Real-time enrollment, referral, and reward events can trigger Customer.io journeys based on each advocate’s progress.
Four merchants who already had Klaviyo flows and dropped the ReferralCandy referral link straight in.
Klaviyo flows running their affiliate program emails.
Toki Mats wired the ReferralCandy + Klaviyo integration into their affiliate-program email flows — partner onboarding, reward notifications, monthly digest — without leaving the email tool their team already runs.
Farm Hounds sent one Klaviyo campaign with the ReferralCandy referral link inserted as a custom property. One send, $5,000+ in attributable referral revenue. The integration is the punchline of their case study.
Do It Center triggers a Klaviyo flow after every purchase that drops the customer's unique referral link into the email — turning every receipt into a chance to refer.
Klaviyo invitations into the refer-a-friend program.
Renogy uses ReferralCandy's Klaviyo integration to invite recent purchasers into their refer-a-friend program directly from the post-purchase flow they already had running.
Use ReferralCandy with Recharge, Skio, Loop, and other Shopify subscription apps. Apply advocate rewards and friend offers to subscription products, then control how many billing cycles the coupon covers.
Recharge
Subscribers refer subscribers.
Recharge adds a dedicated connection on top of the Shopify Subscriptions API coupon flow. New subscribers can redeem a friend offer at checkout, while advocates can apply earned reward codes to an existing subscription through the Recharge Customer Portal. Other subscription apps use the shared Shopify-native coupon mechanism.
Measure referral traffic and build retargeting audiences.
Use Google Analytics to understand campaign-page visits and referred traffic. Add Google Ads, Meta, or AdRoll tracking to the friend-offer experience to build audiences of referred visitors who have not yet purchased.
Choose the payout method that fits your campaign and finance workflow. With Tremendous, connect your preferred funding source and control the available reward options, branding, and claim experience through a campaign template.
Tremendous
Flexible cash rewards, one connected claim journey.
Use Tremendous as the cash payout method for referral and affiliate campaigns. Choose the funding source, select a campaign template for the reward options and branding, and give recipients a clear email-to-claim experience.
Common questions about installation and what each integration unlocks.
How long does the Shopify install take?
On Shopify, ReferralCandy is a one-click install from the Shopify App Store. Most merchants finish setup the same afternoon — install, pick reward rules, drop the post-purchase widget into the theme, run a test order to confirm tracking.
What data does ReferralCandy track and where does it sync?
Every referral event — sign-ups, link clicks, code redemptions, completed orders, rewards earned and paid — is tracked in real time and exposed via Klaviyo profile properties, GA4 events, your ad pixels, and the standard ReferralCandy API.
Do I need a developer to install ReferralCandy?
Not for Shopify, BigCommerce, WooCommerce, or Recharge — those are all one-click. Magento and custom stores need a 5-minute paste of a JavaScript snippet, or a deeper API integration if you have unusual checkout logic.
How does the Klaviyo integration work?
ReferralCandy sends every referral event to Klaviyo as a profile property and an event. You can trigger flows when a customer signs up to refer, when a friend redeems a code, or when an advocate earns a reward — and segment audiences by referrer status.
How does the Customer.io integration work?
Import all of your Customer.io contacts or one segment and enroll them as advocates in ReferralCandy. Optionally, write each advocate’s unique referral link back to Customer.io, push real-time enrollment, referral, and reward events into your journeys, and use a reporting webhook to enroll new subscribers automatically. ReferralCandy and Customer.io emails remain independent, so you decide which platform sends each message.
Which subscription apps does ReferralCandy work with?
Recharge connects through its dedicated Shopify Checkout integration, including reward-code redemption for existing subscriptions in the Recharge Customer Portal. Skio, Loop, Bold, Awtomic, Stay AI, RecurPay, SEAL, Subi, Appstle Subscriptions, PayWhirl, Smartrr, and Joy Subscriptions use the same Shopify-native subscription coupon mechanism, with controls for eligible purchase types and the number of recurring billing cycles a coupon covers.
Does ReferralCandy track referral revenue in GA4?
ReferralCandy can connect to a separate Google Analytics 4 property so you can measure visits to your ReferralCandy pages and understand how visitors reach them. This keeps ReferralCandy reporting distinct from your storefront property and makes campaign traffic easier to analyze.
What does migrating from another referral or affiliate app look like?
Import your existing advocate or affiliate list via CSV and keep the coupon codes they’ve already been sharing. Run ReferralCandy in parallel with your current tool during the handover, then switch when you’re ready. We regularly migrate merchants from Friendbuy, Mention Me, Smile, Refersion, Okendo, and Yotpo — your onboarding manager walks you through the specifics.
What if my tool isn’t on this page?
The email and messaging integrations listed above are natively wired up. For everything else, our API and webhooks are open, and Zapier covers a lot of the rest (we have customers bridging into Circle, Slack, and HubSpot via Zapier today). Tell us what you’re using and we’ll point you at the right install path.
One install. Every integration.
Plug ReferralCandy into your stack and let referrals show up in the tools your team is already in — Shopify, Klaviyo, Recharge, your ad pixels, Tremendous. No new dashboards to learn.
