# I Will Build a WhatsApp AI Chatbot with API Integration

Your customers are already on WhatsApp. The question is whether your business is ready to serve them at 2 a.m. on a Sunday — automatically, intelligently and professionally. That is exactly what this service delivers.

I build custom WhatsApp AI Chatbots and Agents using the official WhatsApp API and OpenAI-powered language models, tailored specifically to your business goals. Whether you need to handle FAQs, capture leads, accept bookings, or guide customers through a purchase, I design conversational flows that feel natural and convert.

\*\*What is included in every tier:\*\*
 • Official WhatsApp API setup and connection to your business number
 • AI language model (LLM) integration, trained on your knowledge base
 • Pre-set conversational journey mapped to your use case
 • Rich media support — images, PDFs, buttons and menus
 • Automated replies based on live user input
 • Source code delivered with your order
 • Unlimited revisions until you are satisfied

\*\*Standard and Full tiers also include:\*\*
 • CRM or database integration so every conversation syncs with your records
 • Google Sheets integration for lightweight data capture
 • WhatsApp Broadcast setup for approved template messaging
 • Extended build time to handle more complex flows and thorough testing

\*\*How it works:\*\*
 1. Place your order and share your business details, knowledge base content and any existing CRM or tool credentials.
 2. I design and [build your](https://zinnhub.com/zinns/build-ai-chatbot-website-saas-app-using-gpt-gemini-langchain-pinecone/) chatbot flows, integrate the AI model and connect your WhatsApp API.
 3. You review the live chatbot, request any revisions, and I deliver the final solution with source code.

\*\*Who this is for:\*\*
 This service is ideal for healthcare clinics, real estate agencies, eCommerce and Shopify stores, event and webinar businesses, hotels, restaurants, and coaching or fitness studios — any business that wants to stop losing leads to slow or absent customer communication.

\*\*Why Zinn Digital®:\*\*
 With 100+ successful WhatsApp API projects completed, I work exclusively with official WhatsApp API tooling — no hacks, no grey-area methods, no risk to your business number. I am based in London, England, and provide post-delivery support to make sure everything continues running smoothly after handover.
