Square's connection tile is not available in ShipStation Legacy.
If you can’t see the store connection tile when you search for Square, it’s most likely because you are in ShipStation Legacy. You may only connect Square in the current version of ShipStation, so this is a good time to upgrade or at least try it out.
If you do move back to Legacy, your Square store will still work just fine. The store connection and tile visibility are the only things affected. Everything else about the integration should work the same in both versions.
To connect your Square store to ShipStation:
Select the Square tile.
Log in to your Square account to authorize access for ShipStation.
After you've completed the connection steps, your store will be connected to ShipStation. You'll be taken to the store's Settings page to adjust the store-specific settings like branding, notification preferences, and product handling.
Square Online Stores will only accept a single shipment notification from ShipStation.
This means, if you split orders into multiple shipments, ShipStation will only send the tracking/fulfillment details to Square for the final shipment on the order.
Only a single Square store can be connected to a ShipStation account.
