Banking for non US business account

I have set up a business Alpaca account for a non-US resident company and I need some guidance on how to transfer funds into and out of Alpaca.

The standard procedure for US residents does not seem to work. In particular, it does not seem to recognise my non-US bank’s SWIFT code, which I have confirmed separately.

Is there any help available for transferring funds into non-US business trading accounts?
