Building an AI Product Catalog Agent with Shopify and WhatsApp

On November 12, 2026, the AI section of DEV Community published an article titled "Building an AI Product Catalog Agent on Shopify and WhatsApp," laying out a blueprint for assembling an e-commerce agent. The piece describes pulling price and stock data from Shopify and letting the LLM handle only the task of phrasing a short reply, framing that division of labor as the core of a product catalog agent. It also stresses the use of tool calling as a guardrail against discount hallucination, making clear that the LLM should never fabricate discounts.

On the implementation side, the article proposes building on Omdaa webhooks together with n8n and Omdaa AI. It lays out a typical sales flow in sequence: begin with a disclosure and greeting, then call the search_products tool to answer a category or product request, surface two to three options with links, and close with a checkout link or hand off to a human closer. The article further states that every Omdaa product and feature — including sessions, messages, Webhooks, Omdaa AI, MCP, mail, and analytics — is 100% free forever, with no subscription, no credit card required, and no hidden pricing tiers.

At this point only this single write-up has surfaced. The topic remains at the stage of a design walkthrough, and no follow-up reports on actual deployment or further updates have appeared.
