Why integrate Code with ShipStation
The Code to ShipStation 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.
Push every Shopify order to ShipStation the moment it's placed
When an order comes in, MESA sends it to ShipStation with the right shipping method, carrier, and fulfillment rules already applied. Your team picks up a ready-to-ship order, not a configuration task.
Route orders to the right warehouse based on what's in the cart
When an order contains specific products, a wholesale flag, or a regional destination, MESA reads the details and sends it to the correct ShipStation fulfillment location. Every order reaches the right facility without manual sorting.
Update Shopify the moment ShipStation marks an order shipped
When ShipStation generates a tracking number and marks an order fulfilled, MESA writes the update back to Shopify and triggers any downstream actions — a Klaviyo notification, a customer tag, a loyalty point. Your post-purchase workflow starts the moment fulfillment does.
Build any Code and ShipStation automation
MESA helps you connect apps to automate repetitive tasks. A trigger is an event that starts a workflow, and actions are the steps that occur when it's running.
