Klaviyo is a cloud-based email marketing platform that allows merchants to target, personalize, monitor, and optimize marketing campaigns. With the Klaviyo integration, you can run ReferralCandy campaigns with your Klaviyo flows.
Note: This guide covers the current one-click connection. If your account still uses a private API key, see the upgrade notice below.
Integrate ReferralCandy with Klaviyo
Go to your Integrations > Klaviyo page:
Click Connect.
You're redirected to Klaviyo. If prompted, sign in and follow the sign-in prompts.
Review the requested permissions, then click Allow to connect ReferralCandy.
Once access is granted, you are taken back to ReferralCandy. Open Integrations > Klaviyo and check for the green Connected badge.
Avoid duplicate emails: Set up and test your Klaviyo flows first. Then, in the relevant ReferralCandy campaign, open Emails and turn off the equivalent emails you will send from Klaviyo. See Klaviyo: Setting up your email flows for which emails to turn off.
Confirm the Klaviyo integration
In Klaviyo, open Integrations. On the Apps page, find ReferralCandy under My apps and check that its status is Enabled. You can also find the integration's test profile, candybot@referralcandy.com, under Audience > Profiles.
After connecting, use ReferralCandy events and custom properties to personalize your messages, then choose and set up your email flows.
