Hello,
CODE: E00027
EXPLANATION: The transaction was unsuccessful.
DESCRIPTION: An approval was not returned for the transaction.
INTEGRATION SUGGESTIONS: This error may occur for merchants on the HSBC or FDI Australia processors when setting validationMode to liveMode as these processors do not support authorization reversals. We recommend HSBC and FDI Australia merchants set validationMode to testMode instead.
Here are some troubleshooting steps you can take:
- If you are using HSBC or FDI Australia processors make sure liveMode is set to testMode.
- Make sure you are not accidentally using your developer account or have your account set to test mode.
- Make sure you are not in test mode and triggering a specific testing response.
- Make sure you are using the correct account credentials (api login and transaction key).
- Make sure you are using TLS 1.2 (e.g. make sure you are not using TLS 1.0 or 1.1).
- If testing using a live account make sure the credit card is valid.
