        "content": "## AI support reply drafting (Zendesk + Shopify)\n\nWhen a customer writes on a Zendesk ticket, this workflow pulls the thread and the customer's recent Shopify orders, asks Claude for a reply in your house style, and posts it as an **internal note**. Nothing reaches the customer unless a person clicks Approve in Slack, and only high-confidence drafts with nothing left to verify get that button. Everything else is edited and sent by the agent in Zendesk.\n\n**Setup**\n1. Credentials: Zendesk API, Shopify Access Token (custom app with read_orders; new custom apps are created in the Shopify Dev Dashboard), Anthropic API, Slack.\n2. Zendesk webhook to this workflow's production URL, plus a trigger: *Ticket is Created or Updated*, *Comment is Public*, *Current user is (end-user)*. JSON body:\n`{\"ticket_id\":\"{{ticket.id}}\",\"subject\":\"{{ticket.title}}\",\"requester_id\":\"{{ticket.requester.id}}\",\"requester_email\":\"{{ticket.requester.email}}\",\"requester_name\":\"{{ticket.requester.first_name}}\"}`\n3. Replace REPLACE_WITH_ZENDESK_SUBDOMAIN, REPLACE_WITH_SHOP (the myshopify subdomain) and the Slack channel IDs.\n4. Paste your tone guide and policy summaries into STYLE and POLICIES in **Build drafting prompt**.\n\n`claude-haiku-5-5` is a cheaper option for high-volume, simple classification; keep Opus or Sonnet for drafting.\n\nTemplate by Lumeor Studio, https://www.lumeor.studio/guides/ai-support-reply-drafting/",
