I need a small, self-contained script that signs in to NetSuite through the appropriate API (SuiteTalk, REST Web Services, or a RESTlet—whichever you feel is the most secure and sustainable) and then downloads a specific report whose URL I will feed in as a parameter. The output must always be saved in CSV format; no other file types are necessary. Configuration items such as account ID, credentials / OAuth tokens, and the report link should sit in an external file or clearly marked variables so I can update them without touching the core logic. When you hand it over I expect: • A working script with clear inline comments. • A brief README explaining any required libraries, token generation steps, and how to invoke the download with a new report link. If you have a preferred language or SDK, state it up front—Python, Node.js, or even Java are all acceptable as long as the end result is a reliable one-command pull of the CSV.
