# Test mode: Fail an InboundTransfer

Transitions a test mode created InboundTransfer to the `failed` status. The InboundTransfer must already be in the `processing` state.

## Returns

Returns the InboundTransfer object in the returned state. Returns an error if the InboundTransfer has already failed or cannot be failed.

## Parameters

- `failure_details` (object, optional)
  Details about a failed InboundTransfer.

  - `failure_details.code` (enum, optional)
    Reason for the failure.
Possible enum values:
    - `account_closed`
      The bank account has been closed.

    - `account_frozen`
      The bank account has been frozen.

    - `bank_account_restricted`
      The bank account has restrictions on either the type or number of transfers allowed. This normally indicates that the bank account is a savings or other non-checking account.

    - `bank_ownership_changed`
      The bank account is no longer valid because its branch has changed ownership.

    - `debit_not_authorized`
      Debit transactions are not approved on the bank account.

    - `incorrect_account_holder_address`
      The bank notified us that the bank account holder address on file is incorrect.

    - `incorrect_account_holder_name`
      The bank notified us that the bank account holder name on file is incorrect.

    - `incorrect_account_holder_tax_id`
      The bank notified us that the bank account holder tax ID on file is incorrect.

    - `insufficient_funds`
      The bank account has insufficient funds to cover the debit transaction.

    - `invalid_account_number`
      The bank account details on file are probably incorrect. The routing number seems correct, but the account number is invalid.

    - `invalid_currency`
      The bank was unable to process this transfer because of its currency. This is probably because the bank account can’t accept payments in that currency.

    - `no_account`
      The bank account details on file are probably incorrect. No bank account exists with these details.

    - `other`
      The bank could not process this transfer.
