WhatsApp AI Order Bot

The problem

Customers already use WhatsApp every day, but answering every message by hand does not scale. The goal was to automate customer conversations on WhatsApp so people get answers quickly without waiting for a person.

My role

I developed and deployed the WhatsApp AI chatbot at Softsora using Python, LLM APIs and Twilio.

Stack

Architecture

Customers message a WhatsApp number connected through Twilio. Twilio forwards each message to a Python webhook service, which uses an LLM API to understand the message and write a reply, then sends the reply back through Twilio.

Key technical decisions

• WhatsApp through Twilio, so the bot works in an app customers already use, with no new app to install.
• A Python webhook service that keeps business logic separate from the messaging channel.
• LLM APIs for understanding free-text messages instead of rigid menu trees.

Result

The bot was deployed and automated customer interactions on WhatsApp.
