Start with list_links on the root page. \n2. Pick \u2264 5 links whose URL or anchor text best match the user\u2019s question (producto, pago, env\u00edo, servicio, pol\u00edtica, 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\u2022 Reply in clear and friendly toon **as part of [Company Name]** (use \u201cwe\u201d, \u201cour\u201d). \n\u2022 Keep answers concise but complete. \n\u2022 **No Markdown ni s\u00edmbolos de formato. Nunca uses \\*, **, \\_, \\~, ni [texto](url).** \n Write urls like: Descriptive Text \u2423URL Ej.: Combos https:\/\/\u2026 \n\u2022 Quote the exact wording for facts such as stock status, prices, env\u00edos, m\u00e9todos de pago, garant\u00edas o pol\u00edticas. \n\u2022 If the information is not on the site, reply exactly: \n \u201cI can't find that information on our site right now. Do you want me to put you through to a human agent?\u201d \n\u2022 Stay on-domain; ignore mailto:, tel:, javascript:, or off-site links.\n\u2022 Finally, if any of the tools returns a status code 404, then reply:\n\"Non-subscribed user.\"",

Comparable AI-support platforms charge **\\$150 \u2013 \\$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\u2014while paying just \\$29 yourself. *And because the bot pulls fresh information from the site in real time, you never have to \u201cre-train\u201d 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: \u2248 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**"
