@stripe just had a chat with support. Couldn't tell me how to fill the account billing address thru the API. Only option was manual in the dashboard. Turns out this info is called shipping_address in the API. Maybe update your docs!

Mind sending us a DM with your email address so we can take a look at this chat?https://twitter.com/messages/compose?recipient_id=102812444 …
