Course enrollment AI agent on WhatsApp
Answers questions about your courses, schedules and prices on WhatsApp, and registers students for the next group.
How it works
Trigger: WhatsApp — a student sends a message
- A student asks about a course on WhatsApp.
- The agent checks your Courses sheet for dates, times, price and seats left.
- It collects the student's name, level and preferred group, then registers them.
- It sends payment instructions and alerts your team on Telegram.
What it can do
Unlike a fixed flow, an agent decides which of its tools to use, in what order — and remembers the conversation.
- Answers in Arabic dialects or English from your live course list
- Suggests the right level and group
- Registers students with name, phone, course and group
- Shares your payment instructions after registering
System prompt
The instructions that shape the agent. It's already inside the n8n template — copy it into Make or Zapier, and adjust the YOUR_… parts.
You are the WhatsApp enrollment assistant for YOUR_ACADEMY. Reply in the customer's language and dialect (Egyptian Arabic, Gulf Arabic, Modern Standard Arabic or English). Be warm and brief.
Today is {{ $now.toFormat('cccc d LLLL yyyy') }}. Payment instructions: YOUR_PAYMENT_INSTRUCTIONS.
Tools:
- "Courses": our course list (course, level, group, days, time, start date, price, seats_left, online or in person). Always check it before answering about dates, prices or seats.
- "Register student": saves a registration. Use only after the student confirms the course, group, their full name and level (and the parent's name if the student is under 18).
- "Notify team": alerts our team about every registration, and any question you can't answer (refunds, certificates, special prices, complaints).
Rules:
- Never invent courses, dates, prices, discounts or certificates.
- Only offer groups with seats_left above 0. If a group is full, offer the next one.
- If they're unsure of their level, ask 2–3 short questions about what they already know, then suggest a level.
- After registering, share the payment instructions and say the team will confirm their seat once payment arrives.Safety rules
Built into the prompt and the tools:
- Never invents courses, dates, prices or discounts
- Never promises certificates or results you don't offer
- Hands parents' and payment questions it can't answer to the team
Uses your own AI key (Claude, OpenAI or another model). Cost depends on the model and conversation length — a small, fast model keeps most conversations to a fraction of a cent.

Code
JavaScript used in the Code step — already included in the template below.
// Keeps only text messages and pulls out who sent it and what they asked.
const msg = $input.first().json.messages?.[0];
if (!msg || msg.type !== "text") return [];
return [{ json: { from: msg.from, question: msg.text.body } }];Build it
Pick your tool — same automation, step by step.
Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder. AI steps use a Claude model node — swap it for OpenAI, Gemini or Ollama if you prefer.

}In Make, create a new scenario and add these modules in order:
- WhatsApp Business Cloud › Watch Events (messages)
- Tools › Set variable / Iterator + Array aggregator (same logic as the Code step)
- Make AI Agents › Run an agent — give it these tools: “Courses” (Google Sheets), “Register student” (Google Sheets), “Notify team” (Telegram Bot); paste the system prompt as the agent's instructions
- WhatsApp Business Cloud › Send a Message
- Every module run uses Make operations — the free plan includes a monthly quota.
- Make's built-in functions (map, sum, formatDate…) can replace most Code steps; for complex logic use a code module.
- Module and step names can differ slightly as Make and Zapier update their apps.
In Zapier, create a new Zap and add these steps in order:
- WhatsApp — New Message
- Code by Zapier — Run JavaScript (paste the code from the Code section)
- Zapier Agents — create an agent (or AI by Zapier for a single step) — give it these tools: “Courses” (Google Sheets), “Register student” (Google Sheets), “Notify team” (Telegram); paste the system prompt as the agent's instructions
- WhatsApp — Send Message
- Zaps with more than two steps need a paid Zapier plan.
- Webhooks, Filters/Paths and Code by Zapier are premium features on some Zapier plans.
- Code by Zapier runs JavaScript: reuse the code shown above, reading inputs from inputData instead of $json.
- Module and step names can differ slightly as Make and Zapier update their apps.
Tips
- Update the seats_left column after each payment so full groups are never offered.
