Error Handling

It is recommended that you implement error handling to catch errors that the API may return, see the example code below. A list of status codes and their description can be found here.

// call the API 

    // print the error
    os.Stderr.WriteString(fmt.Sprintf("Pdfcrowd Error: %s\n", why))

    // print the error code
    os.Stderr.WriteString(fmt.Sprintf("Pdfcrowd Error Code: %v\n", why.getCode()))

    // print the error message
    os.Stderr.WriteString(fmt.Sprintf("Pdfcrowd Error Message: %v\n", why.getMessage()))


  • Refer to the API Status Codes page if the API returns an error.
  • You can use setDebugLog and getDebugLogUrl to get detailed info about the conversion, such as load errors, load times, browser console output, etc.
  • Check the FAQ.
