Project Brief We need a developer to implement a WhatsApp Business API (Meta) bidding/auction flow for our logistics procurement.
When an order is confirmed in our “Daily Order Book” dashboard, it should be sent to eligible vendors (mapped by From/To/Vehicle Type). Vendors bid via WhatsApp (structured), can improve bids, and our dashboard shows live L1/L2/L3 rankings. After close, we award a winner and get vehicle confirmation via WhatsApp.
Deliverables (Phase 1)
WhatsApp Business API integration (templates + webhooks)
Auction creation/publish/close logic
Vendor mapping logic (eligibility rules)
Bid capture + validation + bid improvements
Ranking engine (L1/L2/L3) + bid history
APIs for dashboard to display bids + status
Award + winner confirmation flow
Documentation + basic tests
Key constraints
Official WhatsApp Business API only (no unofficial automation)
Vendors must not see competitor identity/rates beyond allowed rules
Please include
Relevant WhatsApp API examples
Timeline estimate + fixed quote in INR (milestone breakup)
