# Verifying a bank account in sandbox

When you create a bank account (`POST /v3/funding-accounts/banks`) in the production environment, you must complete bank account verification (`POST /v3/funding-accounts/banks/{bankAccountId}/verify`) before the account can be used for other BILL operations.

In the sandbox environment, you can now set `depositAmount` as `0.50` to complete bank account verification.

See [Bank account setup (v3 API)](https://developer.bill.com/v3/docs/bank-account-setup-v3-api) for more information.
