# Verify a bank account

`POST /v3/funding-accounts/banks/{bankAccountId}/verify`

Verify an existing bank account.

When you create a bank account, BILL sends a test ACH payment to the bank account to confirm whether the account details are accurate. Enter the test amount as the `depositAmount` value in your `POST /v3/funding-accounts/banks/{bankAccountId}/verify` request.

**Note**: Bank account verification is required in the production environment before the account can be used for other BILL operations. In the sandbox environment, set `depositAmount` as `0.50` to complete bank account verification.

The bank account `status` is set as `VERIFIED` when BILL is able to verify the `depositAmount` value. BILL sends an email notification for confirming a test transaction. When BILL cannot verify the bank account after three attempts, you cannot use the bank account. At this point, use another bank account or create a bank account with `POST /v3/funding-accounts/banks`.

After your bank account verification is complete, ensure that the current bank account user `verificationStatus` is set as `VERIFIED` before you can use the bank account. To begin the verification process, nominate a bank account user with `POST /v3/funding-accounts/banks/users/nominate`.
