To operate payouts, our clients have to top up a Wallet held with TrueLayer. Wallets are issued with their own virtual IBANs and are connected to the Faster Payments Scheme. When a client comes to send a payment, they should first check the balance of the wallet to ensure that they have the funds required to execute the payments. When instructed, TrueLayer then executes the payment to the specified end account and reports the status back to our client.
The payout flow is entirely server-side.
