3. Create Your First n8n Workflow

Build a simple auto-responder:

Add Webhook node to receive WaSenderAPI messages

🧠 Advanced Workflow Example

Routes to sales if existing contact
Sends onboarding sequence if new lead
Logs all interactions automatically

// Sample n8n Function Node Code
if (input.json.sender === "+1234567890") {
  return {
    priority: "high",
    department: "support"
  };
}
