WhatsApp, as the most downloaded social networking application in the global Apple App Store, encompasses three main members: WhatsApp Messenger, WhatsApp Business, and WhatsApp Business API.
Now, let's see the differences.
WhatsApp Messenger, the inaugural release, primarily caters to individual users, facilitating daily communication and interaction.
WhatsApp Business targets small and medium-sized enterprises, addressing various business needs.
WhatsApp Business API, an extension of the aforementioned versions, offers enhanced commercial capabilities. It fulfills larger enterprises' demands in customer communication and management, enabling official bulk messaging, and making it the preferred choice for sizable corporations.
As of now, Willdesk supports integration with WhatsApp Business API accounts. WhatsApp Business API accounts do not require linking with Facebook but need to be created and managed under Meta's Business Manager. You can refer to the following link for integration steps.
