Did Not Receive Command Result

If a card-present transaction fails with Did Not Receive Command Result, the terminal lost its connection mid-transaction, but that does not necessarily mean the transaction failed. Use the guidance below to confirm the true result before retrying.

Error Message: Did Not Receive Command Result

Environment: Occurs on card-present transactions via a terminal.

Root Cause: The terminal lost connection in the middle of the transaction (typically due to a network issue).

How To Resolve: It is important not to assume the transaction failed just because this error occurred. Depending on when the connection was lost, the transaction may have actually approved prior to the error.

To determine whether the initial transaction was successful, send the same webhook_id value on a subsequent request. When you send the same webhook_id, our system returns the cached result of the initial transaction attempt:

• If the original transaction was successful, you will see a successful transaction result returned when you send the duplicate webhook_id on the follow-up request.
• In a true failure scenario, you will receive the error response again. You can then send a new transaction request with a new webhook_id value to retry the transaction.
