Marketing Automation Script Coding

I need a compact, well-commented script that supports one of our current marketing campaigns. The job is a small task: pull performance data from a single ad platform’s API, format the response, and drop the results into a CSV so my team can review the numbers in Excel without touching the code... (Budget: $15 - $25 USD, Jobs: API, Data Processing, Google Chrome, JavaScript, Node.js, Python, Script Writing, Software Architecture)
