Why integrate Code with Klaviyo
The Code to Klaviyo integration helps you sync data, automate manual tasks, and keep your stack aligned — without writing code.
Connect any API your workflow needs
When a workflow needs to reach a service MESA doesn't natively support, Custom Code makes the connection. Write an HTTP request, parse the response, and pass the data to the next step — all in one workflow.
Apply pricing or discount rules unique to your store
Custom Code runs JavaScript against live order data, letting you calculate custom pricing tiers, apply business-specific discounts, or validate order details before anything processes downstream.
Encode business logic no built-in tool can match
Every operation has edge cases that standard tools can't anticipate. Custom Code lets you write the exact logic your business needs and slot it into any workflow step — validations, lookups, or calculations.
Keep Klaviyo profiles current as customers shop
When a customer's behavior changes in Shopify — a new purchase, a tag update, a loyalty tier change — MESA updates their Klaviyo profile in real time. Your segments and flows always reflect who your customers are right now.
Trigger Klaviyo flows from any Shopify event
When an order is placed, a subscription starts, or a customer hits a milestone, MESA sends the signal to Klaviyo and starts the right flow. Your email automation runs on the full range of what happens in your store, not just native Shopify triggers.
Suppress the right customers from campaigns automatically
When a customer files a return, opens a support ticket, or enters a sensitive window, MESA updates their Klaviyo suppression list or profile status. Your campaigns reach the right people at the right time without manual list hygiene.
