# Create transfer

> Creates a transfer between accounts in the authenticated caller's program.

`Idempotency-Key` is optional. Reuse the same key with an unchanged request to prevent duplicate execution. Without a key, do not retry an unknown outcome until you reconcile the `from` account's Portfolio transactions.

Once recorded, a key remains globally reserved beyond 24 hours and cannot be reused for another transfer, including one for a different acting user or account.
