How do I integrate a chatbot with a CRM system for personalized responses?

<!-- BEGIN COPY / PASTE -->
    const axios = require('axios');

    async function getCustomerData(userId) {
      try {
        const response = await axios.get(`https://api.crm.com/customers/${userId}`, {
          headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
        });
        return response.data;
      } catch (error) {
        console.error('Error fetching customer data:', error);
      }
    }

    async function handleChatMessage(userId, message) {
      const customerData = await getCustomerData(userId);
      if (customerData) {
        return `Hello ${customerData.name}, how can I assist you today?`;
      } else {
        return "Hello, how can I assist you today?";
      }
    }
