Transaction Inquiry (Type 22) is used to inquire about the status of a transaction.

By using a token or unique ID from the original authorization, the transaction inquiry does not require the cardholder’s account number. However, in an error recovery situation, the response is not returned to the POS. The POS application retains the original transaction details until a successful authorization response is received. This transaction does not communicate to a third-party processor and functions without the need for Elavon Gateway applications to reach the host.

Transaction Inquiry performs the following functions:

- Whenever a transaction status is uncertain, you can run Transaction Inquiry (22) to determine whether the transaction exists in the database.
- Is sent after a POS timeout when an error prevents your POS application from receiving or processing the response data from the Elavon Gateway or a communication failure occurs.
- The POS must be able to determine if transaction response is the expected response (is the amount correct) in the transaction lifecycle, because the system only returns the current state of the last transaction approved.


Transaction Inquiry searches the active (main) database for:

- Reference Number (Field 0007).
- Token (Unique ID) or Account Number (Field 0003).
- Transaction Amount (Field 0002). In the event of a partial authorization request, this amount may differ in the completed transaction.
- Partial Authorization Acceptance (Field 0647). If this field 0647=1 in the request message, indicating a partial authorization, the system will allow the requested amount.
- Elavon Gateway Terminal ID (Field 0109). Provided in the request message.
- If the transaction is not found, the transaction can be resubmitted by the POS application for processing.

:::::notice{note}
Your POS application must support the Transaction Inquiry transaction type.
