Steps
Authenticate all Column API calls using HTTP Basic Auth with your API key as the username and an empty password
Create a bank account for your customer via POST /transfers/bank-accounts with the account holder's name and type (checking or savings), and link a routing and account number or use Column-issued account numbers
Verify available balance via GET /accounts/{id} before originating any payment
Originate a domestic wire via POST /transfers/wires with the source Column account ID, destination bank routing number and account number, amount in cents, and a description
Column submits the wire to Fedwire on your behalf; monitor wire status via the transfer.wire.created and transfer.wire.completed webhook events
For wire returns, Column fires a transfer.wire.returned event; reconcile returned amounts against your internal records using the wire ID
Known gotchas
Column is a direct Federal Reserve member bank — wires originate via Fedwire directly, not through a correspondent; Fedwire cutoff times (6:00 PM ET) apply
Column's API uses amounts in cents (integer minor units); passing a decimal amount will result in a validation error
Column accounts are real FDIC-insured bank accounts — sandbox and production are strictly separated; never mix API keys between environments
