Payzink API returns a standardized set of status codes to indicate the result of a transaction or payment-related operation.

These codes help you determine whether a request was successful, requires additional customer action (e.g. 3D Secure), or failed due to an error such as invalid card details, insufficient funds, or suspected fraud.

Each status code follows a structured format and is grouped into logical categories:

• SUCCESS (Sxx): The transaction was approved or completed successfully.
• ERROR (Exxxxxx): The transaction failed due to validation, card, or processing issues.
• FRAUD / RISK (Fxxxxxx): The transaction was declined due to fraud detection or high-risk assessment.

By checking the status code in the API response, your system can determine the appropriate next step (e.g. display a message to the user, retry the transaction, prompt 3DS authentication, or block the request).

The following table lists all available status codes and their meanings:
