The "ERROR-001" error occurs when there is no PDF file provided. This means that the required pdf_file parameter in the POST request was null or empty.

Please note: Be sure to check the parameter syntax, the file path of the PDF file, or the validity of the PDF stream.
Tips: Ensure the pdf_file parameter is set to your PDF file in the POST request.

Example of pdf_file proper syntax in cURL:

curl -X POST 'https://api.securedoc.com/v1/document-services/pdfs/redact-text?words_to_redact=IRON' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@YOUR_PDF_DOCUMENT.pdf;type=application/pdf'
SHELL

Refer to the final line for proper usage:

-F 'pdf_file=@YOUR_PDF_DOCUMENT.pdf;type=application/pdf'

Explanation

  • -X POST: Specifies the request method as POST.
  • URL: The API endpoint URL that processes the PDF document.
  • -H 'accept: */*': Header indicating the server can respond with any content type.
  • -H 'Content-Type: multipart/form-data': This header specifies that the POST request contains a form with data, which can be files and parameters.
  • -F 'pdf_file=@YOUR_PDF_DOCUMENT.pdf;type=application/pdf': This flag uploads a file; the @ symbol before the file name indicates that the name after the @ is a file path. The type=application/pdf ensures that it is treated as a PDF.

Make sure that the path to YOUR_PDF_DOCUMENT.pdf exists and points to the actual PDF file you want to use.
