Indicates the result of a tender transaction, reported by the
tender service provider. This property must be present on all
responses. Possible values are:
- `ACCEPT` - The tender service provider processed the transaction successfully.
- `ERROR_INVALID_TOAST_TRANSACTION_TYPE` - The requested Toast-Transaction-Type is not valid.
- `ERROR_INVALID_INPUT_PROPERTIES` - The specified JSON properties in the request body are not valid.
- `ERROR_INVALID_TOKEN` - The token supplied in the `Authorization` header field is invalid.
- `ERROR_INVALID_RESTAURANT` - The restaurant specified by the `Toast-Restaurant-External-ID` is invalid.
- `ERROR_ACCOUNT_INVALID` - The tender identifier provided did not correspond to an account, or the account
is not valid at the current restaurant.
- `ERROR_ACCOUNT_NO_POST` - The tender identifier provided corresponded to an account which has no card on file or
has been marked as "no post".
- `ERROR_FOLIO_IN_USE` - Some property management systems limit guest folio access to one source at a time. If the front desk agent is using the property management system to access a guest folio, it may be locked and therefore unavailable for room charge posting during that time.
- `ERROR_INSUFFICIENT_FUNDS` - The payment or tip, specified in TENDER_RETRIEVE_PAYMENTS or TENDER_RETRIEVE_GRATUITY,
cannot be retrieved because the tender account does not have sufficient balance.
- `ERROR_UNABLE_TO_PROCESS` - The transaction cannot be processed by the partner.
- `ERROR_TRANSACTION_DOES_NOT_EXIST` - The transaction that is being requested to be reversed or updated
does not exist. Only occurs on a `TENDER_REVERSE` or `TENDER_GRATUITY` response.
- `ERROR_TRANSACTION_CANNOT_BE_REVERSED` - The specified transaction cannot be reversed. Only `TENDER_REDEEM`
and `TENDER_GRATUITY` transactions can be reversed.
