What Katana asks for
The Katana connection form asks for two fields: REST API Key and UserID.
REST API Key: the API key generated in Extensiv 3PL Central that gives Katana access to your warehouse data.
UserID: the numerical identifier of the API user. It is not an email address, which is a common mistake.
Find your credentials in Extensiv (3PL Central)
If you are a brand whose 3PL uses Extensiv
Contact someone at your 3PL who can generate REST API Keys, and ask them to create keys for you.
Ask them to assign these read permissions: CustomerView, FacilityView, InventoryDetailView, InventoryRead, ItemView, OrderView, PoView, ReadPropertiesThirdParty, and ReceiverView.
Katana sends sales orders to Extensiv, so also ask for these write permissions: ItemEdit, OrderConfirm, OrderEdit, OrderWrite, PoEdit, and ReceiverEdit.
Confirm you received the numerical UserID, not an email address.
If you are the 3PL
Fill out Extensiv's API Integration form. The key must give access to all customers within your 3PL.
For question 5 (Your Customer's Name), enter All Customers.
For question 6 (Customer ID in 3PL Warehouse Manager), enter 0.
For question 7 (What type of API connection would you like to set up?), choose External API.
Extensiv 3PL Central will email you the credentials shortly afterward.
