How to Get an API Key

Log in to your CallFlow account
Navigate to API settings in the dashboard
Generate a new API key with desired permissions
Use the key in your authenticated requests

⚠️ Store your API key securely—never expose it in client-side code or public repositories.

const axios = require('axios');

axios.post('https://api.callflow.com/api/v1/call', {

    headers: {
        Authorization: `Bearer YOUR_API_KEY`,
        'Content-Type': 'application/json'

    console.error('Error initiating call:', error.response?.data || error.message);
});
