META Business Account
In the course of setting up the WhatsApp Business Account at the interface of WhatsApp, a link to the META Business Account is required. This link is done automatically in the setup process. Since the WhatsApp Business API can only be used by businesses, the link is used by Facebook to verify that your business is a real business and not a private individual.
WhatsApp Account /WhatsApp Business Account (WABA)
A WhatsApp account with the API can be created directly via the process in Superchat. In this step, the META business account to which the WhatsApp account is to be linked is also selected at the same time.
The WhatsApp account can then be easily managed in the WhatsApp Manager via the META company account.
WhatsApp Profile
A WhatsApp profile is a number that can be added to a new or existing WhatsApp account. So if you want to add a new number to an existing WhatsApp account with the WhatsApp Business API, you have to create a new profile (with this number).
