WhatsApp Auction Backend Integration
Freelancer.com creative contest — guaranteed prize of $100 USD. I run an active auction group on WhatsApp (members connect through Android devices) and now need a purpose-built backend that plugs into the WhatsApp Business API to keep each sale organised and transparent. Core flow • Capture every bid that comes into the group, store it with timestamp, bidder ID, and item reference. • Push instant “you’re now the highest bidder” or “you’ve been out-bid” alerts back to the bidder. With each bid the time to bid on that specific item gets extended with 10 seconds and auctions is done lot by lot. •
