Checkout Links integrates directly with Klaviyo through OAuth, so you can send personalised checkout links from your Klaviyo flows and from Shopify Flow.
Connecting Klaviyo
Go to Settings > Klaviyo in the Checkout Links app
Click Connect Klaviyo
Sign in to your Klaviyo account and authorise the connection
Once connected, you'll see your Klaviyo account status on the settings page
You can disconnect at any time from the same settings page.
What you can do with Klaviyo
Abandoned cart recovery
Send abandoned cart emails with checkout links that restore the customer's exact cart. Use dynamic link parameters with Klaviyo merge tags to rebuild the cart items and pre-fill customer information.
How it works:
A customer abandons their cart
Klaviyo triggers your abandoned cart flow
The email includes a checkout link with the abandoned products passed as URL parameters
The customer clicks and goes straight to checkout with their cart restored — plus any promotion you've added (like 10% off to incentivise completing the purchase)

Reorder reminders
Send customers a link to reorder products they've previously bought. Especially effective for consumable products on a predictable replenishment cycle.
How it works:
A customer makes a purchase
After a set period (for example 30 days), Klaviyo triggers a reorder flow
The email includes a checkout link that pre-fills the customer's details and re-adds their previously purchased items
One click and they're back at checkout ready to reorder

Customer pre-fill
Use Klaviyo's customer data to pre-fill checkout information and reduce friction:
https://yourstore.com/offer?c=##{{ person.id|default:'' }}The customer's name, email, and shipping address are filled in for them at checkout.
Triggering from Shopify Flow
If you'd rather trigger checkout link emails from Shopify Flow instead of from a Klaviyo flow, Checkout Links also adds a Send Checkout Link Flow action that sends a link via Klaviyo. See Shopify Flow.
