2. Transaction errors
The list of error messages is non-exhaustive and contains error messages that you may never encounter, often because they don't apply for your account type or because they're payment method specific.
In general, error codes starting with:
- 2 mean the status is "uncertain". This will usually evolve to a final status.
- 3 mean the transaction is declined by the acquirer or blocked by the Fraud detection module
- 4 mean the transaction is declined. It could be only a temporary technical problem. Please retry a little bit later.
- 5 mean a validation/configuration error (e.g. currency not allowed on your account).
For a list of all possible error codes and messages, please log on to your ePDQ account and check the "List of the payment statuses and error codes" in the "Selected user guides" section of the Support menu.
