I have a File_Upload field on my app in the Creator. When I am tying to upload a file using the Advanced Rest Client (Google App), I can see the status code '200 OK' , but the response is empty. Also, the file does not get uploaded in the database/table. Below are the Name-Value fields that I am passing in the Data Form section of the Advanced Rest Client:

authtoken      :  **************

scope            :  creatorapi

applinkname  :   rest

formname      :   FormA

fieldname       :  File_upload

recordId         :  3246746000000040119

filename         :  ZOHO.png

The link that I am using:  https://creator.zoho.com/api/xml/fileupload/

My question is how can I just provide the file name and expect it to know the location of the file to upload in the table. I think that my value for the filename field is not in the correct syntax. Do I need to make use of the Files column on the Advanced Rest Client app for uploading a file? 

Any help is much appreciated. Thanks.
