The Challenge

The client struggled with manual, fragmented workflows across WhatsApp and web platforms. Customer interactions required significant human intervention, causing delayed responses, inconsistent pricing, and higher costs. Users were forced to switch between platforms, creating slow, inefficient journeys. Secure backend integration with Shopify and pricing engines posed additional operational challenges, requiring a scalable, automated solution.

Solutions

• WhatsApp requests processed by Amazon Bedrock for intent identification and AWS Lambda routing
• AWS Lambda retrieves Shopify product details, creates orders, and sends confirmations via WhatsApp
• Device images uploaded to Amazon S3 with AWS Lambda performing valuation using Amazon RDS catalog and pricing logic
• Backend Seller API integration for settlements using AWS Secrets Manager credentials
• Conversational responses delivered through templates or Amazon Bedrock in the user’s language
• Meta WhatsApp Manager handles delivery with data stored in Amazon DynamoDB/Amazon S3
• Amazon CloudWatch monitoring with Amazon S3 media retention for auditing

The Results

Delivered 50% faster order processing with streamlined WhatsApp integration, one-click purchases, simplified onboarding, and a smooth user experience that enhanced conversion rates.
