WhatsApp has a feature that allows people to create links, so any user can click and start a conversation (chat) directly with the person who created the link. This functionality is called "click to chat" and as you don’t have to save anyone’s phone number to message them, it simplifies interaction.
Even so, creating WhatsApp links is not user friendly. That’s where Walink comes in, we provide a tool which you can use to generate shortened WhatsApp links, with the api.whatsapp domain. This will increase your chat conversions, and it’s free!
