Automated Tender Scraper Development

I need a reliable web scraper built for a private tender-listing site. The scraper must log in, navigate through pagination, navigate to each tender page and pull the tender data along with these data points:

• Tender title and full description
• Submission deadline and any stated requirements
• Attachment links (PDFs and zip)
• Terms and conditions text

All scraped records should be compiled into clean, well-structured JSON. I will call the tool from Make.com, so the scraper must run in APIFY or similar service.

Core expectations
1. Config file where I can update credentials and target URLs.
2. Graceful handling of redirects, or session expiry.
3. Scraping by provided date
3. Incremental scraping: on repeat runs the script should fetch only new tenders.
4. Deployment to APIFY or similar environment where I can call it from Make.com (APIFY module or http request)
5. Clear README covering setup, dependencies, and typical run command/input JSON.

My target is to implement solution which I can request from Make (every hour or so), and if new tenders, it return those.
