statusstringrequired
For bank accounts, possible values are `new`, `validated`, `verified`, `verification_failed`, `tokenized_account_number_deactivated` or `errored`. A bank account that hasn't had any activity or validation performed is `new`. If Stripe can determine that the bank account exists, its status will be `validated`. Note that there often isn’t enough information to know (e.g., for smaller credit unions), and the validation is not always run. If customer bank account verification has succeeded, the bank account status will be `verified`. If the verification failed for any reason, such as microdeposit failure, the status will be `verification_failed`. If the status is `tokenized_account_number_deactivated`, the account utilizes a tokenized account number which has been deactivated due to expiration or revocation. This account will need to be reverified to continue using it for money movement. If a payout sent to this bank account fails, we'll set the status to `errored` and will not continue to send [scheduled payouts](https://stripe.com/docs/payouts#payout-schedule) until the bank details are updated. For external accounts, possible values are `new`, `errored`, `verification_failed`, and `tokenized_account_number_deactivated`. If a payout fails, the status is set to `errored` and scheduled payouts are stopped until account details are updated. In the US and India, if we can't [verify the owner of the bank account](https://support.stripe.com/questions/bank-account-ownership-verification), we'll set the status to `verification_failed`. Other validations aren't run against external accounts because they're only used for payouts. This means the other statuses don't apply.
