What Katana asks for
The Katana connection form asks for four values from BEST Inc.: Partner ID, Partner Key, Customer Code, and Base URL.
Partner ID: identifies your company to BEST Inc.'s warehouse gateway.
Partner Key: signs every request, so treat it like a password and keep it within your team.
Customer Code: the code for the warehouse account whose inventory and orders you want to sync, for example ACME.
Base URL: the gateway address BEST Inc. assigned to your account.
Find your credentials in BEST Inc.
BEST Inc. issues all four values when it switches on API access for your account. There is no self-service page in the BEST Inc. portal where you can generate them, so start by contacting BEST Inc.
Contact your BEST Inc. account manager or integrations contact. Ask them to enable open API access for your account.
Wait for BEST Inc. to complete its onboarding review. Once it clears, they send you the Partner ID and Partner Key together.
At the same time, ask for your Customer Code. If your company has more than one account with BEST Inc., ask which code covers the warehouses you want to connect.
Also ask for your Base URL. BEST Inc. uses several gateways and assigns different ones to different accounts, so you can't guess this value or copy it from someone else. It looks like http://gateway-name.example-best.com/gateway/api/glink. If you receive separate sandbox and production URLs, use the one that matches the account you are connecting.
Enter all four values in Katana's connection form. Enter the Base URL exactly as given, with no trailing slash.
If a value is rejected, contact BEST Inc. They issue and activate the credentials, so they are the fastest route to a fix.
