AI Agent WhatsApp Customer Support for Luxury Boutique

Client's Goal: A high-end clothing boutique needed a 24/7 WhatsApp customer support agent that could handle audio, image, and text inquiries—delivering fast, intelligent, and natural responses to elevate their client experience.

Challenges: The boutique’s team was overwhelmed by after-hours WhatsApp inquiries, especially voice notes and images from international shoppers. Manual replies were slow, inconsistent, and often missed the context or tone expected by luxury clientele.

Solution & Approach: I built and deployed a fully automated, multimodal WhatsApp agent using n8n, the official WhatsApp Business Cloud API, and OpenAI. The system receives WhatsApp messages in any format (audio, image, text), processes them with advanced AI models, and replies in the most natural way—audio for audio, text for images or text—while logging every interaction for analytics and improvement.

WhatsApp Integration: Receives audio, image, and text messages via the official WhatsApp Business API.

Audio Message Handling: Transcribes incoming voice notes (using OpenAI Whisper), generates contextual replies, and sends back AI-generated voice responses.

Image Understanding: Analyzes photos or screenshots with OpenAI Vision, crafts descriptive or context-aware replies, and returns them as WhatsApp text.

Conversational Text Replies: Handles text queries with GPT-4 for highly natural, human-like conversations.

Dynamic Workflow Branching: Adapts to each customer’s journey, switching logic based on message type and ongoing context.

Message Logging & Analytics: Tracks all inbound/outbound messages in structured formats (JSON/CSV) for compliance and optimization.

Content Moderation & GDPR Compliance: Uses AI moderation, supports data retention/deletion policies, and ensures all data is handled per WhatsApp and GDPR requirements.
