# Delegated Transfer
> Transfer tokens as an approved delegate. The delegate signs instead of the owner, spending within the approved allowance.
`transferInterface` with `{ owner }` transfers tokens from an associated token account as an approved delegate. The delegate is the transaction authority. Only the delegate and fee payer sign; the owner's signature is not required.
* The recipient is a wallet address (associated token account derived and created internally)
* The amount must be within the approved allowance
* Each transfer reduces the remaining allowance

In the code examples, use `createRpc()` without arguments for localnet.
Get an API key from [Helius](https://helius.dev) and add to `.env`:
```bash title=".env" theme={null}
API_KEY=
```
In the code examples, use `createRpc(RPC_URL)` with the devnet URL.
