Start with list_links on the root page. \n2. Pick ≤ 5 links whose URL or anchor text best match the user’s question (producto, pago, envío, servicio, política, etc.). \n3. For each chosen link call get_page once. \n4. Read the returned text and look for the answer. \n5. If the answer is still unknown, you may repeat steps 1-4 one level deeper. \n6. Stop after two list_links rounds **or** eight get_page calls (whichever comes first).\n\nANSWER RULES\n• Reply in clear and friendly toon **as part of [Company Name]** (use “we”, “our”). \n• Keep answers concise but complete. \n• **No Markdown ni símbolos de formato. Nunca uses \\*, **, \\_, \\~, ni [texto](url).** \n Write urls like: Descriptive Text ␣URL Ej.: Combos https://… \n• Quote the exact wording for facts such as stock status, prices, envíos, métodos de pago, garantías o políticas. \n• If the information is not on the site, reply exactly: \n “I can't find that information on our site right now. Do you want me to put you through to a human agent?” \n• Stay on-domain; ignore mailto:, tel:, javascript:, or off-site links.\n• Finally, if any of the tools returns a status code 404, then reply:\n\"Non-subscribed user.\"", "returnIntermediateSteps": true }, "promptType": "define", "hasOutputParser": true }, "retryOnFail": false, "typeVersion": 1.7, "alwaysOutputData": true, "waitBetweenTries": null }, { "id": "3953a213-6140-4603-a069-93718e4d8982", "name": "list_links", "type": "@n8n/n8n-nodes-langchain.toolHttpRequest", "position": [ 260, 420 ], "parameters": { "url": "https://example.invalid/REPLACE_WITH_N8N_ENDPOINT", "method": "POST", "sendBody": true, "parametersBody": { "values": [ { "name": "url", "value": "https://www.your-company-url.com", "valueProvider": "fieldValue" }, { "name": "auth-token", "value": "REPLACE_WITH_AUTH_TOKEN", "valueProvider": "fieldValue" } ] }, "toolDescription": "Returns up to 100 unique, fully-qualified INTERNAL links for a given page.\n\nInput (JSON body the model must supply)\n {\n \"url\": \"\"\n }\n\nBehaviour\n • Crawls only the domain of the input URL.\n • Converts relative values to absolute URLs.\n • Drops empty roots (\"/\"), mailto:, tel:, javascript:, and off-site links.\n • De-duplicates the list.\n • Responds with a JSON object:\n\n {\n \"urls\": [ \"\", \"\", … ]\n }\n\nUse this tool when you need a navigation map of the current page.\nPass one of the returned URLs back into other tools (e.g. get_text) to read its content.\n" }, "typeVersion": 1.1 }, { "id": "21ceaf5e-d2d4-47c3-98cb-ee7c0ab0fcab", "name": "OpenAI Chat Model", "type": "@n8n/n8n-nodes-langchain.lmChatOpenAi", "position": [ 40, 340 ], "parameters": { "model": { "__rl": true, "mode": "list", "value": "REPLACE_WITH_RESOURCE" }, "options": {} }, "typeVersion": 1.2 }, { "id": "7e0e84c8-ad96-44d1-9de9-c639230418fd", "name": "WhatsApp Trigger", "type": "n8n-nodes-base.whatsAppTrigger", "position": [ -260, 140 ], "parameters": { "updates": [ "messages" ] }, "typeVersion": 1 }, { "id": "c2a0ba34-4a23-4918-9be8-7b9d50279cde", "name": "cleanAnswer", "type": "n8n-nodes-base.code", "position": [ 1040, 120 ], "parameters": { "jsCode": "// cleanAnswer – run once per item\nlet txt = $('AI Agent').first().json.output || '';\n\n// 1.

Comparable AI-support platforms charge **\\$150 – \\$500 each month**, so with this template you either save a large chunk of that expense for your own business or earn the same amount by reselling the chatbot to clients—while paying just \\$29 yourself. *And because the bot pulls fresh information from the site in real time, you never have to “re-train” a model, saving you even more time and money.***\n\n **Activate your membership here:** [https://lemolex.gumroad.com/l/ejsnx](https://lemolex.gumroad.com/l/ejsnx)\n\n### Let's start setting this up step by step:\n*Total hands-on time: ≈ 15 minutes*\n\n1. Activate the tools with the membership generated key: \n- Go to the membership link to get your key.\n- Copy the key (e.g 6F0E4C97-B72A4E69-A11BF6C4-AF123456) and paste it in the body parameters of list_links and get_page (tools):\n*Name: auth-token*\n*Value: 6F0E4C97-B72A4E69-A11BF6C4-AF123456* **(example)**\n\n2. Customize for Your Company:\n- Copy the Root URL of your company's website (Home Page).\n- Open the AI Agent node and inside the `System Message`, change the following values:\n[Company Name] with your company name (e.g [Company Name] -> Facebook)\n[https://www.your-company-url.com] with your company Root URL that you copied before.\nCheck for these 2 values along the entire text.\n- Go back to the tools list_links and get_page and paste the Root URL inside the body parameters, specifically:\n*Name: url*\n*Value: https://www.your-company-url.com **(e.g https://www.facebook.com)**\n\n3. Connect your credentials:\n- Go to the OpenAI Chat Model node and connect your OpenAI credentials.\n- Go to the Postgres Users Memory node and connect your Supabase credentials. A tutorial for this: https://youtu.be/6w5f_jsPYSQ?si=MPdXYUjxv3fghQPj&t=105 (Minute 1:45 to 5:00)\n- Go to the WhatsApp nodes \"WhatsApp Trigger\", \"Send Pre-approved Template Message to Reopen the Conversation\" and \"Send AI Agent's Answer\" to connect your credentials. A tutorial for this: https://youtu.be/ZrhTQle55LQ?si=MO_leooogO9KchCV\n- Go to the \"Send Pre-approved Template Message to Reopen the Conversation\" and select the template message under the \"Template\" parameter.\n***If you don't want to use this feature (not recommended) delete the nodes \"24-hour window check\", \"If\" and \"Send Pre-approved Template Message to Reopen the Conversation\". Then connect the AI Agent node to the \"cleanAnswer\" node.***\n\n\n### **You are ready**" }, "typeVersion": 1 }, { "id": "255b90df-8991-5e42-a63e-0f076406245c", "name": "Publication · Overview and setup", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -1720, -320 ], "parameters": { "content": "# AI Customer-Support Assistant · WhatsApp Ready · Works for Any Business\n\n## Purpose and structure\nThis folder contains the **AI Customer-Support Assistant · WhatsApp Ready · Works for Any Business** workflow.
