Hi Doug - during the login process one of the pages that shows is a list of accounts that you are authorizing. The account in question was not listed there, right?
before today, Schwab API was restricted to not work with a bunch of account types. One of the things we were waiting for was for the update that went in last night to enable a whole bunch of different account types. However, I believe they still have some more to do, and I assume the Trust type is one of them. I will check with them about that.
