Additions and changes to the Twilio platform
You can now send and receive contact cards, also known as VCards or VCF (Virtual Contact Files), via WhatsApp! Contact cards let people easily share and add new contacts to their phone book.
When a user receives and taps on a vCard in WhatsApp, the app will render a preview and allow them to easily call or add the contact to their phone book.
In WhatsApp, VCards are useful for businesses that send links to users, but have not yet been able to become an Official Business Account. For these businesses, links will only be clickable when the business has been added as a contact.
To send a vCard, simply send it as a file as you would with any other media.
