Quickstart: Withdraw to Bank

Sending funds from your Circle Account to an external bank account is one of the most basic primitives (building blocks) enabled by the APIs. This quickstart walks through sending USDC USD externally. You can follow the same steps when sending EURC EUR as well.

1. Get an API key

Circle's APIs use API keys as the mechanism to authenticate client requests. The API key must be set in the Authorization header of the request sent from your backend server. The format of the header is Bearer secret-key-value.

To obtain an API key for the sandbox environment, simply create an account and generate a new key in settings - it only takes a few seconds.

GET AN API KEY

Once you have generated your API key, record it in a secure place.

2. Link a bank account

To send account funds externally, you will need a bank account to send to.

You can use the create a wire bank account API endpoint to link a sample bank account.

NOTE - the parameters listed below are slightly different for US Bank accounts, Non-US bank accounts - IBAN supported and Non-US bank accounts - non-IBAN supported. Please see the above link for details.

3. Fund Your Account

If you haven't done so already, make sure you fund your account for testing. You can do this one of two ways: by using the Circle Payments API to accept a payment, or by receiving an external USDC transfer from a faucet or other source.

4. Send Funds

To send funds externally, you can use the create a payout API endpoint.

}

5. Check the Status of the Transfer

You can use the get a payout API endpoint to retrieve details about the status of the transaction. You can use it as in the command below.
