Steps to Split PDF with C# Low Code API

  1. Configure the PdfApi class object using the client ID and secret
  2. Upload the source PDF file to the cloud by assigning a name for subsequent reference
  3. Invoke the PostSplitDocument method to split PDF files by pages within a specified range
  4. Iterate through the collection of split PDF documents and download each PDF file
  5. Save each PDF file as a separate file using the unique name assigned by the API

These steps summarize the development of the PDF splitter software with C# .NET-based API. First, load the source PDF file to the cloud to split it page-by-page, and call the PostSplitDocument() method in the PdfApi class to split it. Provide the necessary parameters, such as reference to the uploaded PDF file, format of the file, starting page number, ending page number, and a few optional parameters if required.
