WhatsApp API Documentation

The WhatsApp APIĀ  enables you to send and receive messages through your Whatsapp account.

The WhatsApp API is based on the WhatsApp WEB protocol which means that your account can be banned by the WhatsApp anti-spam system when some recipients click the “BLOCK” or “SPAM”. So, avoid sending messages to people who did not subscribe to your list or platform.
