Transfers
Move money between a customer's own Citi accounts or to and from linked external bank accounts.
Overview
The Transfers API moves money between a customer’s own accounts and to or from external bank accounts they’ve linked. Use it for internal transfers (checking to savings), external ACH transfers, and same-day options when speed matters.
Transfer types
Make a transfer
Internal transfers post instantly. External ACH transfers show a PENDING status until they settle, usually within 1–3 business days.
Cutoff times
Same-day ACH transfers must be submitted before the daily cutoff (typically 2:00 PM ET on business days). Transfers submitted after cutoff, on weekends, or on bank holidays settle the next business day.
Security requirements
Requests require an OAuth 2.0 access token with the payments:write scope. See the Authentication guide.
