Connect your Squarespace store to Katana (via Extensiv Integration Manager) to automate order and inventory management.
What you can do with this integration
Import sales orders from Squarespace → Katana
Sync sales order fulfillment from Katana → Squarespace
Push inventory levels from Katana → Squarespace
How it works
In Extensiv, the order destination is a WMS (Warehouse Management System). Authorize Katana as a WMS to act as the source of truth for inventory.
Squarespace is set as a Cart (Order Source). Extensiv imports sales orders with product + customer details from Squarespace into Katana, and passes inventory levels from Katana back to Squarespace.
When tracking info is added to a Katana sales order (SO) and the order is marked as Packed or Delivered, Extensiv pushes this update back to Squarespace.
Adding tracking info to Katana SOs is required for fulfillment sync to work.
Connecting Squarespace to Katana
Step 1: Log in to Extensiv
Log in to Extensiv (or create an account).
Step 2: Connect Katana as WMS
In Extensiv, open up Integration Management
Go to WMS and click Change WMS. Then, choose Katana MRP from the WMS list.
Click Grant Us API Access, sign in to your Katana account, and confirm.
After successful authorization, click OK, then Test WMS Connection.
If the test succeeds, click Save.
Step 3: Add Squarespace as cart
Go to Carts > New Setup > and choose Squarespace.
Fill in the API information and click Grant Us API Access.
A Squarespace login window will open — log in and authorize Extensiv.
You’ll be redirected back to Extensiv, which will confirm if authorization was successful.
