ShipStation · InfiPlex OMS Integration
ShipStation Integration: multichannel orders, your existing shipping workflow
ShipStation handles rates, labels, and your carrier accounts well — but it doesn't aggregate orders across 130+ channels or sync inventory between them. The InfiPlex™ OMS connects both directions: it consolidates orders from every channel and sends shipment-ready orders to ShipStation for label generation, and it can also pull orders directly from ShipStation via API — filtered by a specific order status if needed — then set tracking on those orders back in ShipStation via API. Large warehouses commonly use the direct-pull model.

How it works
How the InfiPlex ShipStation integration works
There are two ways InfiPlex connects with ShipStation, and which one fits depends on where your orders actually originate. Most sellers use the aggregation model: InfiPlex consolidates orders from every sales channel and sends shipment-ready orders to ShipStation for rate comparison and label generation using your existing carrier accounts. Large warehouses more often use the direct-pull model instead: InfiPlex pulls orders straight from ShipStation via API — filtered by a specific order status if needed — and sets tracking on those orders back in ShipStation via API once they ship. Either way, your team's packing and printing workflow in ShipStation doesn't change.
Two ways to connect
Aggregate Into ShipStation, or Pull Directly From It
Which model fits depends on where your orders actually originate.
-
Aggregation (Most Common)
InfiPlex consolidates orders from 130+ channels and sends shipment-ready orders into ShipStation for label generation.
-
Direct Pull (Large Warehouses)
InfiPlex pulls orders straight from ShipStation via API — filtered by order status if needed — and sets tracking on those orders back in ShipStation via API.
Your carrier setup, unchanged
Rate Shopping & Multi-Carrier Accounts
ShipStation's rate comparison and carrier account management is exactly why sellers keep it — InfiPlex doesn't touch that layer.
-
Your Accounts, Your Rates
Orders sent to ShipStation use your existing negotiated carrier rates and account settings — InfiPlex doesn't insert its own carrier logic into that step.
-
Batch Shipping Still Works
Orders InfiPlex sends to ShipStation are available for batch processing the same way any ShipStation order would be.
-
Cost Visibility Depends on Your Plan
Shipment and tracking data syncs back into InfiPlex; cost-specific reporting depends on what ShipStation returns through its API for your specific plan.
What’s included
Everything the ShipStation integration handles for you
-
Multichannel Order Aggregation
Orders from 130+ channels pull into one queue, ready to send to ShipStation — something ShipStation's own per-channel connections don't do alone.
-
Or Pull Directly From ShipStation
Large warehouses often flip the model: InfiPlex pulls orders straight from ShipStation via API, filtered by order status if needed, and sets tracking back on those orders via API.
-
Your Existing Carrier Accounts
Rate shopping and label generation in ShipStation use your negotiated rates and settings, unchanged.
-
Real-Time Inventory Sync
One pool across every channel you supply, with per-SKU Safety Stock to prevent overselling while ShipStation prints labels.
-
Automatic Tracking Distribution
Once ShipStation generates a label, tracking flows back to the exact channel the order came from — no manual matching.
-
Batch Shipping Compatible
Orders InfiPlex sends are available for your existing batch label workflow, unchanged.
-
Works Alongside 3PLs
Route some orders to ShipStation and others to a connected 3PL, all reconciled in the same inventory pool.
