Hi,
We are trying to migrate from Aspose cloud rest API in rails to a self-hosted Aspose Words Python server since Its not available in Ruby.
In the documentation, there is only basic information regarding merge fields like inserting a string.
Currently We are doing something like in Ruby
@words_api = AsposeWordsCloud::WordsApi.new
mail_merge_request = AsposeWordsCloud::ExecuteMailMergeOnlineRequest.new(template: load_file(@record), data: fields_data)
output_doc = @words_api.execute_mail_merge_online(mail_merge_request)
convert_request = AsposeWordsCloud::ConvertDocumentRequest.new(document: StringIO.new(output_doc).read, format: 'pdf')
@words_api.convert_document(convert_request)
where field data can be something like
{ 
  "format": "html",
  "htmlText":  "<html>
      <body>
        <div>
          <img src='#{img_path}'>
          <div style='text-align: center; width: 90%; margin-top: -5px'>#{caption}</div>
        </div>
      </body>
    </html>" 
}
How to write the similar thing for Aspose.Words-for-Python-via-.NET self hosted instance
