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.",

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**"
