Why integrate Relay with ShipStation
The Relay to ShipStation integration helps you sync data, automate manual tasks, and keep your stack aligned — without writing code.
Break sprawling automations into manageable pieces
Relay lets one workflow hand off to another, so each piece stays focused and easy to maintain. Update or reuse a single step without touching everything downstream.
Catch workflow failures before they cost you an order
When a workflow errors, Relay routes the failure to another workflow that retries the task, alerts your team, or reroutes the order. Nothing silently drops.
Let AI decide how to handle a broken workflow
Your AI assistant reviews the failed step, the data involved, and past outcomes, then chooses whether to retry, escalate, or reroute the task. No manual triage required.
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 Relay 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.
