Creates a transfer to an approved beneficiary. The amount must be a whole number and at least 1,000 in the beneficiary's currency.

A 201 response means the transfer was created for processing; it does not mean the recipient has received the funds. Some accounts require approval first and receive a 202 response instead. Use List or retrieve bank transfers to monitor the final status.

If your account requires transfer approvals, send a stable Idempotency-Key for each approval request. Reuse the same key only when retrying that unchanged approval request. This header does not provide general duplicate protection for transfers that execute without approval.
