Multi-Platform Inventory Update Automation

My goal is to stop touching stock sheets manually and have one reliable workflow that pushes the right figures to several food-delivery storefronts—Talabat, Instashop, Deliveroo and Hungerstation—once every day.

Here is what I need built:

• A script or small service (Python, NodeJS or similar is fine) that pulls the master inventory from my WMS. Do the threshold • Automatic stock-level adjustments on each of the four platforms via their official APIs or, where an API is missing, a proven headless browser approach • An internal accuracy check after each run: compare the numbers reported back by the platform with the source values and flag mismatches in a log or Slack message

Acceptance criteria

1. A single command or scheduled job triggers the complete update cycle daily.
2. Stock levels visible on all four storefronts match the master sheet after the run (tolerance 0).
3. Detailed success / failure log stored locally and optionally pushed to Slack or email.
4. Clean, well-commented code plus a README so future devs can extend it (for example to Shopify or Magento later).

If you prefer particular libraries—Selenium, Puppeteer, Requests, etc.—let me know; I’m flexible as long as the solution is stable. Budget: INR 1500–12500 Skills: PHP, JavaScript, Python, Software Architecture, Node.js, Web Development, API, Automation
