Open a Column bank account and send a domestic wire transfer

Steps

1. Authenticate using HTTP Basic Auth with your API key
2. Create a Bank Account: POST /bank-accounts with description and optionally entity_id if the account is for a sub-entity; receive a bank account ID, account number, and routing number
3. For a domestic wire, create a Wire Transfer: POST /transfers/wire with bank_account_id (source), amount in cents, currency: 'USD', counterparty details (routing_number, account_number, account_type, name, address), and description
4. Wires submitted before Column's cutoff time on a business day are sent same day; those submitted after cutoff or on non-business days are queued for the next business day
5. Poll GET /transfers/wire/{id} or handle webhooks to monitor status (pending, submitted, completed, or returned)
