The API response includes both an HTTP status code and a PDFCrowd-specific reason code. The HTTP status code indicates the general result of the HTTP request, while the reason code provides more detailed information about the specific cause of an error. Always check both codes to accurately diagnose and resolve API errors. For help retrieving errors in client libraries, refer to your library’s documentation on error handling.
If you are troubleshooting an issue, you can enable logging of conversion details with the setDebugLog() API method. When enabled, the logs are available in your conversion log.
