WhatsApp-Based Marketplace MVP Creation

Build a WhatsApp Marketplace MVP (Food, Services & Shops)
I’m looking for a developer/automation expert to build a WhatsApp-based marketplace MVP using Meta WhatsApp Cloud API + n8n + Google Sheets.

The idea is to create a simple marketplace where vendors can register their business on WhatsApp and customers can search for vendors by category and location.

Key Features Needed

Vendor Side (Registration):

Vendor sends “Register” on WhatsApp.

Bot guides through step-by-step registration (category → subcategory → business name → services/products with prices → location).

Vendor details are stored in Google Sheets.

Confirmation message sent once listed.

Customer Side (Search):

Customer sends queries like “Show me restaurants in Mumbai”.

Bot extracts category + location from the message.

Bot searches Google Sheets for matches.

Bot replies with top 3–5 vendor results including:

Business Name

Products/Prices

Location

WhatsApp contact link

Tech Stack

WhatsApp Cloud API (Meta) → Handles communication.

n8n → Automation workflows (registration & search).

Google Sheets → Initial database (Category | Subcategory | Business Name | Services/Products | Price | Location | WhatsApp Link).

Example Flows

Vendor Registration:

Vendor: Register → guided through details → saved to Google Sheets → receives confirmation.

Customer Search:

Customer: Show me restaurants in Mumbai → bot replies with vendor details + contact links.

Roadmap

Phase 1 (MVP): WhatsApp Cloud API + n8n workflows + Google Sheets backend.
Phase 2: Add categories, filters, and vendor dashboard.
Phase 3: Migrate to Firebase/Supabase, add payments, AI-powered search.
