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.

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:** [{{ $env.WEBHOOK_URL }}]({{ $env.WEBHOOK_URL }}\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[{{ $env.WEBHOOK_URL }}] 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: {{ $env.WEBHOOK_URL }} **(e.g {{ $env.WEBHOOK_URL }}\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: {{ $env.WEBHOOK_URL }} (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: {{ $env.WEBHOOK_URL }}\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, "notes": "This stickyNote node performs automated tasks as part of the workflow." } ], "active": false, "pinData": {}, "settings": { "executionOrder": "v1", "saveManualExecutions": true, "callerPolicy": "workflowsFromSameOwner", "errorWorkflow": null, "timezone": "UTC", "executionTimeout": 3600, "maxExecutions": 1000, "retryOnFail": true, "retryCount": 3, "retryDelay": 1000 }, "versionId": "245c3695-7177-4a1d-a33d-7aedd0eccc44", "connections": { "3953a213-6140-4603-a069-93718e4d8982": { "main": [ [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-574a169e", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-313e6c20", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-3ae5dc2e", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-8c405ae8", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-6acc3be7", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-340df0c3", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-a8ea044a", "type": "main", "index": 0 } ], [ { "node": "error-handler-3953a213-6140-4603-a069-93718e4d8982-c52ea301", "type": "main", "index": 0 } ] ] }, "ef403af2-4543-4edb-80ae-afda1e98a2a9": { "main": [ [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-7a1dcc23", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-5336ee23", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-c68fdd8f", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-468cb6ff", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-391ff470", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-fe5edda1", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-5deb4a31", "type": "main", "index": 0 } ], [ { "node": "error-handler-ef403af2-4543-4edb-80ae-afda1e98a2a9-eaa3d1c9", "type": "main", "index": 0 } ] ] }, "21ceaf5e-d2d4-47c3-98cb-ee7c0ab0fcab": { "main": [ [ { "node": "error-handler-21ceaf5e-d2d4-47c3-98cb-ee7c0ab0fcab-d68cc482", "type": "main", "index": 0 } ] ] } }, "description": "Automated workflow: AI Customer-Support Assistant · WhatsApp Ready · Works for Any Business.
