Textyess
Building a Shopify-connected WhatsApp AI agent takes less than a week using modern frameworks and LLM APIs. However, managing Meta Business API verification, template approval queues, strict opt-in compliance, and per-conversation fee pass-through makes self-hosting or replacing it operationally tedious for single stores.
