n8n + LLM：Shopify 品牌 WhatsApp 查单与库存客服 Agent
n8n WhatsApp support agent for Shopify brands
据 n8n 官方模板：WhatsApp 触发 → 意图路由 → Orders/Products Agent 调 Shopify API → 回复或转人工；强调少传 PII。
据公开帖摘要
模板作者 Ruthwik 描述路径：查客户 → Switch 意图（welcome / orderStatus / product / support）→ Orders Agent 或 Products Agent 调 Shopify HTTP → WhatsApp 回复；不清不楚则转发支持渠道。注意 WhatsApp 会话计费、Shopify 限流、以及避免把完整 PII 送给模型。
