Automate Lead Qualification & Customer Support with GPT-4o-mini Agents

Beginner AI Agent Duo: Lead‑Qualifier Task Automator & Ecommerce Chatbot

Status: Ready for Use ✅
Note: This template is built entirely with official n8n nodes—no community‑node installation required.

📝 Description This template demonstrates two beginner‑friendly AI‑agent patterns that cover the most common use cases:

| Agent | Purpose | Flow Highlights | |-------|---------|-----------------| | Lead‑Qualifier Task Automator | Classifies phone‑call transcripts to decide if the caller is a good bulk‑order lead. | Manual Trigger → Code (sample data) → AI Agent (GPT‑4o‑mini) → Structured Output Parser → Set (clean fields) | | Ecommerce Chatbot | Answers customer questions about products, bulk pricing, shipping, and returns. | Chat Trigger (webhook) → AI Agent (GPT‑4o‑mini) with Memory → If node → Order‑placed reply or no‑op |

Both agents run on GPT‑4o‑mini and use n8n’s LangChain‑powered nodes for quick, low‑code configuration.

⚙️ How to Install & Run

Import the Workflow
In n8n, go to Workflows → Import from File or Paste JSON, then save.

Add Your OpenAI API Key
Go to Credentials → New → OpenAI API.
Paste your key from <https://platform.openai.com>.
Select this credential in both OpenAI Chat Model nodes.

(Optional) Select a Different Model
Default model is gpt‑4o‑mini.
Change to GPT‑4o, GPT‑3.5‑turbo, or any available model in each OpenAI node.

Test the Lead‑Qualifier Agent
Click Activate.
Press Test workflow.
The Code node feeds four sample transcripts; the AI Agent returns JSON like:
{ "Name": "Jordan Lee", "Is Good Lead": "Yes", "Reasoning": "Customer requests 300 custom mugs, indicating a bulk order." }

Test the Ecommerce Chatbot
Copy the Webhook URL from the When chat message received trigger.
POST a payload like:
{ "message": "Hi, do you offer discounts if I buy 120 notebooks?" } The AI Agent replies with bulk‑pricing info.
If the customer confirms an order, it appends *; the If node then sends “Your order has been placed”.

🧩 Customization Ideas Refine Qualification Logic** Edit the Task Agent’s system prompt to match your own lead criteria.
Save Leads Automatically** Add Google Sheets, Airtable, or a database node after the Set node.
Expand the Chatbot** Connect inventory APIs, payment gateways, or CRM integrations.
Adjust Memory Length* Change the *Simple Memory node’s window to retain more conversation context.
