How to Send a vCard with Twilio WhatsApp and Node.js

To create and send vCards through the WhatsApp Business API using Node.js, you need to set up your Twilio number with WhatsApp, install dependencies, host a static directory for your vCard file, build the vCard, and then send it via a WhatsApp message. You can use ngrok to expose a public URL for your vCard file and store environment variables in a .env file to access your Twilio credentials. The process involves creating a contact card using the vcards-js package, saving it to a local file, and then sending it through the Twilio SDK as a media message. You can customize your vCard with different properties and send it to WhatsApp users who have sent you a message within the past 24 hours.
