This is a weird situation that might be worth documenting on

https://github.com/lat9/upsoauth/wik...-Client-Secret

below "associate an existing account or create a new one"

If a developer is installing this module, and the business does not have an existing account, you will have to choose "create a new account."

It's best to get the storeowner to go through the account creation process, because they will verify your identity with an EIN or Credit Card number (which the developer probably won't have).

(It seems odd to me that someone would not have a shipping account set up, but this has happened to me a few times and it's always a pain. I think the most common explanation is that they just need a price from UPS, and somehow the shipping is being taken care of by someone else or in some other way.)
