To use WhatsApp as a company, there are two options:
WhatsApp Channel:
This is a relatively new WhatsApp feature that allows companies to share content with a wide audience. Communication is one-sided (only from the company).
WhatsApp Business API:
Userlike offers this feature. The API supports one-to-one communication, whether it's support requests that you receive and respond to via WhatsApp or campaigns, such as sending newsletters via WhatsApp. Communication through the API always takes place in the conversation with the customer, just like you see your conversations with friends and acquaintances in WhatsApp.
