What Katana asks for
The Katana connection form asks for your V1 API Key and API Secret, plus an optional V2 API Key if you want to sync inventory.
V1 API Key: The key generated in ShipStation with the V1 API version selected.
API Secret: The secret generated together with your V1 API Key.
V2 API Key: An optional key generated with the V2 API version selected. Together with the Inventory API add-on, it's required for inventory data.
Find your credentials in ShipStation
In ShipStation, go to Settings → Account → API Settings.
Make sure V1 API is the selected version. Then generate and copy your V1 API Key and API Secret.
Optional, for inventory sync: open your ShipStation account settings, find the Add-ons section, and enable the Inventory API add-on. This is a paid feature purchased through ShipStation.
Optional, for inventory sync, after completing step 3: go back to Settings → Account → API Settings, select V2 API as the version, and generate and copy your V2 API Key.
Important: Inventory data needs both the V2 API Key and the Inventory API add-on. If either is missing, you may see permission errors when connecting.
