This API call is the final step for executing payouts when using a balance with Wise. Upon calling the endpoint, Wise will begin the processing of the transfer, depending on the status of funds.

When using the transfer by transfer settlement model, the following funding type(s) must be used:

* **BALANCE** — Funds are pulled from a multi-currency account held with Wise.

When funding through the Bulk Settlement model, the following funding type(s) must be used:

* **TRUSTED_PRE_FUND_BULK** — Funds for the transfer will be settled through a bulk payment at a later date. This method is not applicable for First Party partner account transfers.

If funding from `BALANCE`, and your multi-currency account does not have the required funds to complete the action, then this call will fail with an "insufficient funds" error. Once funds are added and available, you must call this endpoint again.
